Stormwater Pump Maintenance: How to Prevent Winter Breakdowns

As the rainy seasons are already here, the demands and the risks on your stormwater pump system increase dramatically. Winter brings challenges such as heavy rainfall, twigs, leaves and fluctuating usage — all of which can strain your system. Without proper stormwater pump maintenance, these factors can lead to unexpected failures, costly repairs, and unpleasant disruptions.

At Mawdsleys Pump Services, we specialise in comprehensive stormwater pump maintenance and emergency support, helping our clients stay operational throughout the colder months.

Why Stormwater Pumps Need Maintenance Before Winter

Winter can be one of the harshest times of the year for your pumping system due to several environmental and mechanical factors:

  • Debris: During autumn and winter, the heavy rainfall can guide a lot of leaves, twigs and silt into your system, which can compromise it and is a serious danger.
  • Heavy Rain and Flooding: Increased water inflow forces pumps to work harder for longer, wearing out key components.
  • Reduced Use or Idle Periods: Infrequently used systems can suffer from hardened debris, seized impellers.
  • Electrical and Control Failures: Damp or cold weather can affect control panels, wiring, and sensors, leading to false alarms or total system failure.

Common Winter Pump Problems

Without regular submersible pump maintenance, systems can quickly develop avoidable faults. Below are the most frequent winter issues — and why they happen:

1. Pump Blockages – Twigs, leaves and silt in the impeller and flow channels, leading to inefficiency or pump failure. In winter, these materials harden faster, making blockages more severe.

2. Motor Burnout – Overworking during high inflow events or faulty float switches can cause the motor to overheat and fail. Preventive maintenance can identify early signs of overload.

3. Float Switch Failure – Faulty or dirty floats prevent proper start/stop cycles, causing the pump to either fail to activate or run continuously.

4. Pump Not Turning On -Electrical faults, stuck floats, or seized impellers can prevent activation. Routine inspections catch these before they cause flooding.

5. Pump Not Turning Off – Constant running increases energy consumption and accelerates wear on internal components. This issue is often linked to float switch or relay faults.

6. Frequent High-Level Alarm Activation – A high-level alarm means the pump isn’t keeping up with incoming flow — often due to blockages or component failure. Ignoring it risks flooding and equipment damage.

7. Control Panel Faults – Cold, damp conditions can cause water ingress in control panels, leading to component failure. Regular maintenance keeps panels clean and protected.

8. Non-Return Valve Blockage – If blockage of the NRV happens, the pumps will function much more than usual, and there is an increased risk of flooding and increased energy costs.

How to Prevent Stormwater Pump Breakdowns

Preventative action is always cheaper than emergency repair. Here’s how to prepare your system for winter:

  1. Book a Pre-Winter Inspection: Our engineers will inspect, test, and service your pump, test the control panel and controls to ensure they are in top condition.
  2. Check the Control Panel: If you see any indicators of problems with the system, get in touch with a specialist as the earlier any issues are sorted, the better. 
  3. Check for Standing Water Around Drains: If the sump is overflowing or drains are backing up- this is an indication of a blocked or malfunctioning system.
  4. Schedule Regular Storm Pump Maintenance: Set up an ongoing maintenance plan with Mawdsleys to keep your system reliable all year.

Benefits of Routine Stormwater Pump Maintenance

A structured stormwater pump maintenance plan offers long-term protection and savings:

  • Fewer Breakdowns: Catching faults early reduces emergency callouts and expensive repairs.
  • Energy Costs: Clean, regularly maintained pumps and controls consume less power and operate more effectively and do not use excess energy.
  • Extended Lifespan: Well-maintained pumps last longer, delaying costly replacements.
  • Priority Support: Maintenance customers receive faster response times and emergency service priority.
  • Regulatory Compliance: Stay compliant with environmental standards and receive detailed maintenance reports.
  • Peace of Mind: Regular checks ensure your pump system performs when you need it most — especially in winter.

8 Common Problems with Sewage Pumps and How to Fix Them

Sewage pumps are critical to wastewater management in almost every type of premises — from private homes to large commercial and industrial sites. When they develop a fault, the consequences range from inconvenient to seriously disruptive: backed-up toilets, overflow risk and costly downtime.

This guide covers the 8 most common sewage pump problems, what typically causes them, and what you should do — including when the situation calls for professional sewage pump repair, a maintenance visit or a review of your current servicing arrangement.

If you need urgent help, call our team now on 0117 954 8030. We operate 24/7, 365 days a year.

1. The Sewage Pump Won’t Start

A sewage pump that fails to start is one of the most common call-outs we attend. Causes include:

  • Power supply failure or tripped circuit breaker
  • Faulty control panel or sensor
  • Motor failure
  • Debris or a blockage jamming the impeller
  • Pump seized after a prolonged period without use

What to do: Check the power supply and control panel first. If there’s no obvious electrical fault, do not attempt to free a jammed impeller manually — contact a pump engineer. An experienced technician will carry out a full diagnostic inspection and carry out the sewage pump repair on-site where possible, or arrange a swap-out to minimise downtime.

2. The Sewage Pump Won’t Turn Off

A pump running continuously is often caused by a stuck or failed float switch, or a blockage preventing the water level from dropping. A tell-tale sign is an unexplained spike in electricity bills.

Running a sewage pump dry — without water to cool the motor — will damage the seals and ultimately destroy the pump entirely.

What to do: If the pump is non-critical, isolate it by cutting the power. Then arrange an inspection with an engineer as soon as possible. Float switch replacement is a straightforward sewage pump repair, but left unattended, the fault will cause far more expensive damage.

3. Toilets Are Backing Up

Toilet backups linked to a sewage pump are usually caused by a blockage within the pump, a fault at the sewage treatment plant, or a septic tank that needs emptying.

What to do: Stop using toilets, taps and drains immediately — every flush adds more wastewater to an already overloaded system. Contact a pump engineer urgently. This is not a fault that resolves itself, and continued use will escalate the problem quickly.

4. Leaking from the Pump or Pipework

Leaks are typically caused by cracked pipework, a failed non-return valve, or a perished seal. A failed non-return valve allows sewage to recirculate back into the sump — the pump then has to work harder to keep up, increasing both energy consumption and wear.

What to do: Carry out a visual inspection to locate the source of the leak. If you can identify the failing component, you may be able to order a replacement part and describe the fault clearly when you call. If you cannot identify the leak, contact a pump engineer immediately.

⚠️ Leaks from a sewage pump are a serious emergency. Raw sewage leakage poses a health risk and can cause significant structural damage. Call us now on 0117 954 8030 for fast 24/7 support.

Regular sewage pump maintenance will catch seal and valve deterioration before it becomes a leak — this is one of the most common faults our engineers identify during scheduled service visits.

5. The High-Level Alarm Is Sounding

High-level alarms are designed to trigger when water in the pump chamber rises to a critical level — usually because the pump has failed or is running below capacity.

What to do: Do not silence the alarm and carry on. Switch off the pump, stop using water on the premises, and contact an engineer for emergency assistance. Ignoring a high-level alarm risks sewage overflow.

6. Loud Noises from the Pump (Vibrations, Banging)

Unusual sounds are often caused by loose or improperly secured pipes vibrating under pressure, a malfunctioning check valve causing water hammer, or an impeller that has come loose within the pump casing.

What to do: Carry out a visual check of the pipework fixings and pump housing. If the noise is coming from inside the pump body, do not attempt to access it — arrange an inspection with an engineer who can assess the impeller and valve and carry out the appropriate sewage pump repair.

7. Pump Burnout

Burnout is one of the most costly outcomes of a neglected sewage pump system. Common causes include:

  • Using the wrong pump for the application (wrong flow rate or head pressure)
  • Heavy usage surges exceeding the pump’s capacity
  • A failed float switch causing the pump to run dry
  • Incorrect overload settings on the control panel
  • A partial blockage making the motor draw excessive current

What to do: If you have experienced burnout, the pump will need to be replaced or fully overhauled. More importantly, the root cause needs to be identified — otherwise the replacement pump will suffer the same fate. Speak to one of our engineers about a pump suitability review. Correct sizing, correct installation, and a planned sewage pump servicing schedule are the most effective ways to prevent burnout from recurring.

8. Bad Smells Coming from the Pump

Persistent foul odours usually point to one of three causes: a failed or perished seal on the chamber lid, a cracked vent pipe allowing gases to escape, or stagnant water in a low-usage system where sewage is sitting rather than being regularly moved.

What to do: Have an engineer inspect the pump, chamber lid and vent pipework. In the case of stagnant water, the issue may be resolved by adjusting run times or reviewing the pump sizing. Regular sewage pump maintenance — including checks of seals and vent pipes — will catch this type of deterioration early.

How Planned Sewage Pump Servicing Prevents Most of These Faults

The majority of the faults above share something in common: they don’t appear without warning. Float switches degrade gradually. Seals perish over time. Valves wear. Blockages build up. In almost every case, a planned sewage pump servicing visit would have caught the early signs before they developed into a breakdown.

At Mawdsleys, our sewage pump maintenance visits include:

  • Visual inspection of the pump, chamber and all pipework
  • Float switch and level control testing
  • Non-return valve condition check
  • Motor insulation and current draw testing
  • Wet well cleaning and de-ragging
  • Written condition report with any recommendations

For clients on a servicing contract, we also provide priority response times and discounted call-out rates when emergencies do occur.

If your sewage pump has never been serviced, or your last service visit was more than 12 months ago, it’s worth getting in touch. A single maintenance visit costs a fraction of an emergency repair — and far less than a pump replacement.

Irrigation systems for sports fields

Keep Your Cricket Pitch In It’s Best Shape With A Portable Irrigation System

Cricket season has begun, teams across the nation will be playing regularly from early March to late September and as any player, groundskeeper or spectator of the sport will know that the quality of the pitch is one of the most important parts of the game.

There are also a number of risks that can arise from poor irrigation on sports fields, including injuries and games being called off.

Find out more about why a good quality pitch is so important for the sport – and the options available to ensure yours is exceptional.

 

The England & Wales Cricket Board – Recommended Pitch Quality

Having a high-quality pitch allows players to perform at their best, bobbles and dry patches or cracks on the pitch mean wayward bowls, frustrated players and potential injuries, cricket games usually go on for up to five hours – so it’s essential they can maintain their quality for this long.

A couple of the guidelines the ECB set out to ensure the best quality include:

  • The cricket square requires a firm and even surface.
  • The outfield should provide a ‘fast and true’ surface that provides a good and safe foot for the fielding team to prevent injuries and improve the standard of play.
  • Even at the lowest tier of the game, the ball should bounce properly throughout the game.

How Can A Long Reach Irrigation System Benefit Me As A:

Groundsman:

  • An LRI system allows you to effortlessly maintain your pitch without the time needed for manual watering or budget needed for a pop-up sprinkler system.
  • The versatility of an LRI system means you can water the pitch only when needed, this eliminates the chance of the pitch becoming waterlogged or dried out.
  • Our most popular LRI systems (25 & 50) have a radius of 25m & 50m and are able to run on water supplies with low pressure – meaning you won’t need to invest in upgrading your water system.
  • Keeping on top of your pitches health removes the need for any expensive re-seeding in the future.

Player:

  • A high-quality pitch allows you to play at your best – bowls will run across the wicket smoothly without any bobbles – this also makes for a fairer game.
  • When the pitch is in good condition, fielders will fall less often – reducing the risk of injury.
  • If it is a particularly hot day, the LRI system can be used during the break to ensure it remains at a good standard throughout the day.

Can We Afford To Have A Great Quality Pitch As A Lower-Tier Club?

Despite what you may think, you don’t have to be a high-tier club to have a great pitch. Our LRI systems are ideal for clubs who can’t afford to invest in underground systems or pop up systems – allowing you to quickly water your pitch and even adjust their position to target problem areas where the pitch is frequently drying up.

Get your free quotation today! Call us on 0117 954 8030

What Other Sports Pitches Use Irrigation?

Aside from cricket fields, our LRI systems have proved to be very effective across a number of different sporting fields including:

Football Pitches – In the highest leagues of football, clubs usually have pop-up sprinkler systems and huge grounds teams. Portable irrigation is the perfect solution for having a great quality pitch without the hefty price tag – we have supplied LRI systems to a number of mid to high-tier clubs throughout the years including, Taunton Town FC, Hoddesdon Town FC and Bristol Rovers FC.

Rugby Pitches – Because of the nature of the sport, good irrigation for rugby pitches is absolutely essential, not only is there a lot of wear tear on the pitch – but players tend to get injured more frequently and landing on hard ground can make injuries more severe. We have provided irrigation for all tiers of rugby clubs, from local teams right the way through to Rugby World Cup training grounds.

In addition to these, LRI systems are also used for hockey fields, school sports fields and equestrian centres. They can also be used in industrial application such as dust suppression in quarries.

7 Common Problems with Booster Pumps and How to Fix Them

What Is a Water Booster Pump — and Why Do They Fail?

Booster pumping systems — also called booster sets, water pressure pumps, or pressure pumps — are used to increase water pressure in buildings where it would otherwise be too low. They’re essential in apartment blocks, hotels, schools, leisure centres, and any building where every outlet needs reliable pressure.

When a water pressure pump fails or stops working properly, the impact is immediate. Residents may lose the pressure needed to shower, flush a toilet, or run a tap — and in commercial buildings, a pressure pump failure can shut down operations entirely.

This guide covers the seven most common causes of booster pump and pressure pump failure, what you can check yourself, and when you need to call a pump repair engineer. If your pressure pump isn’t working right now, call us on 0117 954 8030 — our engineers are available for emergency pressure pump repair across the South West.

Booster set image

1. Water Pressure Pump Not Working — Pump Won’t Start

The symptom: No water reaches any outlet fed by the system. The pump may be silent, or it may hum or click without actually running. This is one of the most common reasons customers call us for emergency pressure pump repair.

Why it happens: A pump that won’t start is usually down to a power failure, a low water level in the break tank (which triggers low-level protection and stops the pump as a safety measure), a tripped breaker, a faulty sensor, a control panel fault, or motor failure.

What to check yourself: Confirm there isn’t a power cut affecting the building, and check whether the pump needs to be manually reset after one. Check that the break tank has sufficient water and that the ball valve hasn’t failed.

When to call a professional: If power and water level both check out and the pump still won’t start, stop resetting it — repeated resets can mask a developing electrical or mechanical fault and cause further damage. Arrange a full inspection from a pump engineer.

2. High Running Noise

The symptom: The pump is noticeably louder than usual — grinding, humming, rattling, or vibrating noises that disturb building users or weren’t there before.

Why it happens: Common causes include high demand on the system, incorrect pump positioning, worn or ageing components, and vibration transferring through the pump or pipework into the building structure.

What to check yourself: Check the pump isn’t being asked to meet more demand than it’s rated for, and look for obvious vibration transfer through pipe fixings or the pump’s mounting.

When to call a professional: If noise persists after basic checks, or you’re not confident assessing demand and component wear yourself, arrange a maintenance visit. Vibration isolators such as mats, bases, and springs are often fitted by an engineer as a permanent fix. Read more in our guide to best practice for controlling noise in booster pumping systems.

3. Leakage

The symptom: Visible water around the pump unit, pooling, damp patches, or a noticeable drop in system pressure with no other explanation.

Why it happens: Leaks are commonly caused by broken valves, worn or cracked seals, or water pressure being set too high for the system to handle.

What to check yourself: Visually inspect the pump and its components for the source of the leak — valves, seals, and pipe joints are the most likely culprits.

When to call a professional: If you can’t identify the source, or the leak is from inside the pump casing itself, arrange an inspection rather than letting it continue, as a leak can develop into a full pressure pump failure. If you’re responsible for ongoing maintenance, our free booster pump maintenance inspection checklist covers the key components worth checking regularly.

4. Contamination

The symptom: Discoloured water, an unusual smell or taste, or a positive result from water testing.

Why it happens: Contamination is usually caused by inadequate cleaning of the pump or poor maintenance of the cold water storage tank feeding it.

What to check yourself: Nothing — this is not a DIY check. Do not continue to use water from the system if you suspect contamination.

When to call a professional: Immediately. Switch the pump off and arrange a full inspection with an engineer who can test, clean, and disinfect the cold water tank. This is a health and safety issue, not just a mechanical one.

Leakage and Contamination are serious emergencies which require immediate action! Get in touch with us if you need fast 24/7 support.

5. Low Water Pressure

The symptom: Outlets fed by the booster set deliver weaker water flow than expected — showers losing pressure, taps running slow, or pressure that drops further during periods of high demand.

Why it happens: A drop in pressure can be caused by high demand on the system, the age and suitability of the pump for current usage, a faulty sensor, valve failure, or a leak elsewhere in the system.

What to check yourself: Note whether low pressure happens at specific times (suggesting a demand issue) or constantly (suggesting a mechanical fault), and do a visual inspection of the unit for obvious leaks or damage.

When to call a professional: If a visual inspection doesn’t reveal the cause, arrange for an engineer to assess whether a repair will resolve the issue or whether the pump is no longer suited to current demand and needs replacing. For more detail, see our guide on how to improve water pressure.

6. High Operating Costs

The symptom: A noticeable rise in energy bills that can’t be fully explained by energy price increases.

Why it happens: As pressure pumps age, they become less efficient — particularly when they aren’t professionally maintained. Older pumps lack the efficiency features built into modern units.

What to check yourself: Compare your current bills against historical usage and check when the pump was last serviced or replaced. Persistent inefficiency despite regular maintenance is a sign the unit may be due an upgrade.

When to call a professional: If your bills are rising and you’re unsure why, arrange a pump energy check to get an accurate picture of current performance and whether upgrading could save you money while reducing your carbon footprint.

7. Pressure is too High

The symptom: Pressure noticeably higher than the system is designed for, sometimes accompanied by banging pipes, leaks, or premature wear on fittings.

Why it happens: The most common cause is a faulty pressure relief valve (PRV) — either set too high or stuck open — putting unnecessary strain on the pump and pipework without any benefit to building occupants.

What to check yourself: Check the pressure gauge reading against the system’s intended operating pressure, and try manually reducing the pressure if the controls allow it.

When to call a professional: If the PRV won’t close, or pressure doesn’t drop after adjustment, arrange an inspection from an engineer — a stuck PRV will continue to strain the system until it’s repaired or replaced.

Pressure Pump Troubleshooting: Quick Reference Table

For a fast diagnostic reference, here’s a summary of all seven issues:

#SymptomLikely CauseQuick CheckCall a Professional If…
1Pump won’t start, no water at outletsPower failure, low break tank level, tripped breaker, sensor or motor faultCheck power supply and break tank water levelPower and water are fine but pump still won’t start
2High running noiseHigh demand, poor positioning, worn parts, vibrationCheck demand level and pipe/mounting vibrationNoise persists after basic checks
3LeakageBroken valves, worn seals, excess pressureVisually inspect valves, seals, and jointsSource can’t be identified, or leak is from inside the casing
4Contamination (discoloured/smelly water)Poor pump or tank cleaning/maintenanceNone — do not use the waterAlways — switch off and call immediately
5Low water pressureHigh demand, ageing pump, faulty sensor, valve failure, leakNote when it happens; check for visible leaks/damageCause isn’t obvious from a visual check
6High operating costsAgeing or inefficient pumpCompare bills to usage and last service dateBills keep rising with no clear explanation
7Pressure too highFaulty or stuck pressure relief valve (PRV)Check gauge against intended pressure; try manual adjustmentPRV won’t close or pressure won’t drop

Pressure Pump Failure FAQs

The most common causes are power failure, low water level in the break tank, a tripped breaker, sensor failure, or motor failure. Check the power supply and tank level first — if the pump still won’t start, it’s best to arrange an inspection rather than keep resetting it, as this can cause further damage.

This is usually caused by a faulty pressure switch, a worn impeller, a leak in the system, or the pump being undersized for current demand. A visual inspection can rule out obvious causes, but diagnosing the exact fault usually needs a qualified engineer.

It depends on the age of the pump, the cost of the repair, and how efficiently it’s running. Our engineers will always explain whether a repair makes sense or whether replacement will be more cost-effective in the long run, factoring in running costs as well as the upfront price.

We offer 24/7 emergency pressure pump repair across the South West and South Wales. In most cases, we can have an engineer on-site the same day, and many repairs are completed in a single visit thanks to our parts stock.

If your pressure pump has failed completely, switch it off at the isolator if it’s tripping repeatedly, and avoid repeatedly resetting it. If you suspect a leak or contamination, isolate the system and call us immediately — these need urgent attention.

Booster Pump Set

How Much Could a Booster Pump Energy Check Save You?

 

Booster pumps are an effective method of increasing water pressure and ensuring building users can access water of a suitable pressure, regardless of the number of outlets in use or size of the building.

Booster pumps are often used in larger sized buildings with multiple occupants such as flats, apartment blocks, office buildings, hotels, schools and Government buildings where mains pressure alone isn’t enough to meet demands.

Many booster pumps we find in operation are old units with antiquated controls which become less economical and efficient over time. With environmental impact becoming very important and the cost of electricity always rising, it can pay dividends to understand how economical your pump is and take steps to improve it.

Read our blog post to find out more about the considerable savings that can be unearthed through an energy check, the benefits of a modern booster pump and the importance of keeping your booster set professionally maintained.

Booster Set Energy Check Savings

A pump energy check gives you a clear view of your pumps current performance and the associated cost savings that could be made by upgrading your existing booster pumping system. When carrying out an energy check, the following factors are considered:

  • Pump & head flow
  • Motor power data
  • Operating hours per year
  • Age of pump
  • Pump use
  • Operating needs

From this data, the test can ascertain what energy savings could be made with the installation of a new booster set, including how long the payback time would be.

At Mawdsleys Pumps, we regularly carry out energy checks in line with the ISO 14414 Pump Energy Assessment Standards before making system recommendations to clients, often revealing thousands of pounds worth of energy savings that could be made.

In a recent test we carried out, we uncovered potential savings of over £40,000 over a 10 year period at an NHS facility in Bristol, read the full case study here.

The Benefits of a Modern Booster Set

Modern booster sets are made up of several components designed to enable adequate water pressure to any sized building. As technology has improved, so have the number of benefits a booster set offers, the key advantages are:

  • Variable Speed Drives – Modern booster sets are fitted with variable speed drives, these drives have pressure sensors and flow sensors which keep the pressure constant with varying demand, extending the life of the pump and meaning you only pay for what you use.
  • High Efficiency – As technology has improved, booster pumps have become more and efficient, offering adequate pressure on a normal mains water supply.
  • Environmental Benefits – As a result of improved efficiency and variable speed technology, modern booster sets use less energy, reducing the carbon footprint.
  • Duty, Standby and Assist – Modern booster sets are usually compromised of multiple pumps, meaning that there is a backup should the demand exceed the main pump, plus a standby pump should one fail. These are known as ‘duty’, ‘duty – assist’ and ‘standby’ pumps.
  • Lower Running Costs – Equally, improved efficiency and reduced energy use results in lower overall running costs, building owners can expect a booster pump to pay off its installation cost long before the end of its life.

Keeping Your Booster Set Well Maintained

Due to their critical nature, there is never a good time for a booster pump to fail or start to underperform.

In order to keep your booster set running at maximum efficiency, it is recommended that you have your pump serviced by a professional pump engineer.

As well as keeping the pump running at full strength, regular servicing ensures that any developing faults are rectified, reducing the risk of breakdown.

Additionally, there are maintenance checks such as visual inspections that can be carried out every month to complement annual servicing.

To help keep on top of routine maintenance, we have created a free inspection checklist for responsible persons. Click the button below to download your copy.

Water pressure is an essential part of any building with a water supply, yet it’s often taken for granted until something goes wrong and the pressure drops. Low water pressure can be caused by a number of factors, such as high demand and can affect every water outlet in the premises, including toilets, showers, taps, pumps, washing machines, and water tanks.

Experiencing low water pressure is extremely frustrating for building users and in commercial and agricultural environments, can result in huge drops in efficiency due to the extra time taken to output water. Read our latest blog post to find out more about the causes of low water pressure and how you can improve your water pressure.

Steps To Improving Your Water Pressure

If you’ve noticed a drop in your water pressure, here are steps you can take to try and increase it once more:

  • Check that the outlet for your water is not clogged up or blocked in any way
  • Check that the water valves for your property are fully open
  • Check for blockages in your water system
  • Check for any leaks in your water system
  • Ensure that your current pumping system meets your requirements
  • Test your appliances at peak times vs quieter times to see if there is a difference in the water pressure you receive
  • Invest in appliances such as power showers which can enable higher output even when overall pressure is lower

If you own the premises, you can take it upon yourself to check these or contact a professional if you do not have the expertise.

However, if you are a building user or rent a space in the building, it is likely that you will need to contact the landlord of the building to investigate further.

Benefits of a Booster Pumping System

If you are still struggling with water pressure, it is likely that you need to consider taking measures to increase the pressure of water to your system, this can be done very effectively with a booster pump.

Booster pumps are installed to increase the water pressure throughout a building and are an effective means of improvement in any type of building.

They can be installed in most properties whether you rely on a typical water supply or get your water from a private supply (such as a borehole or well).

A booster pump is a long term investment that will serve your property for years if properly maintained, download our free booster pump inspection checklist to find out more.

Booster pumps are available to suit any premises, whether it’s fixed speed or a range of multiple pump variable speed sets to meet demands and offer energy saving benefits.

Booster Pump Maintenance: Why It Matters

If you’ve already got a booster pump installed and you’re still experiencing low water pressure, the cause is very often poor or missed maintenance rather than the pump being undersized or unsuitable.

Like any mechanical system, booster pumps need regular attention to keep performing at the level they were designed for. Without it, common faults develop gradually — worn seals, failing sensors, clogged filters, or a control panel that’s no longer calibrated correctly — and pressure drops off long before the pump fails completely.

What’s typically included in a booster pump service:

  • Inspection of pump components — seals, valves, bearings, and the motor — for wear or damage
  • Testing of pressure sensors and control panel settings against the system’s intended operating pressure
  • Checking the break tank, ball valve, and low-level protection are functioning correctly
  • Identifying vibration, noise, or leaks before they develop into a larger fault
  • Confirming the pump is still correctly sized for current building demand

How often should a booster pump be serviced?

Most commercial and residential booster sets benefit from a service at least once a year, though buildings with higher demand — such as hotels, leisure centres, or apartment blocks — may need more frequent visits. A planned maintenance contract takes the guesswork out of this by scheduling visits automatically and giving you priority access if something does go wrong between services.

Regular booster pump maintenance is also one of the most cost-effective ways to avoid a full pump failure, since most of the faults that lead to total breakdown are easy and inexpensive to catch early.

Frequently Asked Questions

Can changing a shower head improve water pressure?

Yes, in some cases simply changing the shower head can improve the water pressure you get.

Shower heads can also become blocked up with limescale which restricts the amount of water that can be output, so in some cases a simple clean will help improve the water pressure.

Additionally, some showers have water saving heads that intentionally reduce the water pressure to save money.

How to improve water pressure from a well?

If you rely on a well as your water supply, it’s critical that you get adequate pressure from your system given that there is no backup.

A booster pumping system can be used to effectively increase the pressure received from private domestic water sources.

Can I install a booster pump to the mains water pump?

Yes, a booster pump can be installed to the mains water pump.

However, due to water supply regulations, pumps that draw more than 12 litres of water per minute cannot be connected to a supply pipe without permission, therefore, it’s typically a better option to install a separate water tank for your booster pump.

It’s highly recommended that you engage with a booster pump installation company who will be able to recommend the best course of action based on your situation.

What does a booster pump service include?

A typical booster pump service involves a full inspection of the pump’s mechanical components, testing of pressure sensors and control settings, a check of the break tank and safety devices, and an assessment of whether the pump is still correctly sized for current demand. Our engineers will flag any developing issues and explain whether they need immediate attention or can be monitored.

How much does booster pump maintenance cost?

Costs vary depending on the size and complexity of the system, and whether you’re booking a one-off service or an ongoing maintenance contract. A maintenance contract is usually the most cost-effective option for buildings that rely heavily on consistent water pressure, since it includes scheduled visits and priority emergency cover.

Why Water Pressure Matters

Low water pressure can create several issues in all environments, whether it’s a domestic premises, commercial office or leisure facility.  The most common complaints about low water pressure include:

  • Showers and taps can be reduced to a trickle of water
  • Toilets may not flush properly
  • Results in reduced efficiency in commercial premises
  • Any activities requiring higher pressure, such as irrigation or high-pressure cleaning, may not be possible
  • Certain modern appliances do not work below specific pressure thresholds
  • Equally, certain pumping equipment requires a specific amount of pressure to work

All of this can contribute to a poor experience for the users of the building, and in a commercial building such as a block of flats, gyms, schools or a hotel, is likely to attract complaints.

What are the Causes of Low Water Pressure?

Water pressure is effectively the force that transports water through your pipes, so lower water pressure means that the water flows at a lower velocity.

There are a number of reasons why your water pressure may have dropped. The most common reasons for low water pressure are:

  • When demand for water is higher, pressure may be impacted
  • Properties that have a shared supply are more likely to experience issues with water pressure
  • In larger buildings such as hotels, offices, or blocks of flats, water outlets at the top of the building tend to have lower pressure
  • In gravity fed systems, your water pressure depends on how high the source of water is above your property
  • Additionally, the distance your property is away from the water source will impact the pressure you get
  • Old or damaged pumping facilities may no longer be able to cope with the demands of the building
  • Pipes restricting the flow of water due to diameter, corrosion, blockages, and leaks can reduce the water pressure

A Buyers Guide to Sewage Treatment Plants

When you can’t connect to mains sewerage infrastructure, a sewage treatment plant is the recommended solution for waste treatment and disposal. With septic tanks and cesspits slowly being phased out due to changing legislation and environmental consideration, many buildings across the UK are opting to have sewage treatment plants installed. If you are thinking about having a sewage treatment plant installed at your commercial or domestic premises, our guide helps you understand what sewage treatment plants do, when they are suitable, how much they cost and what the benefits are.

What Is a Sewage Treatment Plant?

A sewage treatment plant is a below ground vessel that acts as an off-mains drainage solution for those that can’t connect to mains sewage. Unlike cesspits and septic tanks, sewage treatment plants treat incoming wastewater to an acceptable level for discharge, making them more environmentally friendly.

How Do They Work?

Sewage treatment plants are multi-chambered units. First, the wastewater produced from the building through toilets, baths and sinks is deposited in the first chamber where the liquids and solids are separated by gravity. The solids remain in the first chamber but the liquids flow into a biological chamber which is filled with compressed air, this helps to speed up the naturally occurring formation of bacteria. Finally, the treated liquid is moved into the final chamber of the tank. Here the bacteria settles at the bottom of the tank to allow it to be moved back into the first tank whilst the clean water remains at the top of the tank. The water at the top of the final tank can then be safely discharged out to a watercourse or to a ground soakaway field.

When Do You Need One?

Under the UK Building Regulations, if you can connect to the mains sewer then you should do this for the removal of sewage and wastewater. However, if you are unable to connect to the mains sewers due to being in a remote location then you can review options for managing wastewater within your property. It’s important to note that the responsibility for the waste produced lies with the owner of the property, so it’s critical that an appropriate solution is installed and properly managed if you cannot access the mains.

How Much Do They Cost?

As sewage treatment plants are far superior to cesspits and septic tanks in how they break down waste to a safe level, they do have a higher upfront cost and there are also additional costs to consider. Once installed, you will need to budget for an annual service of the unit as well as emptying costs. In order to release sewage from the plant, you must first pay a small fee to get Discharge Consent. Other considerations include the electricity costs to run the unit (which are very low due to the efficiency) and any repair and callout costs in the event of a pump breakdown. To find out more, take a look at our blog posts which details all of the costs involved with installing and operating a sewage treatment plant.

What Are the Benefits of Sewage Treatment Plants?

A sewage treatment plant offers several benefits over other methods of sewage treatment such as septic tanks and cesspits. The key benefits include:
  • Treats wastewater to a safe level meaning that it can legally and safely be discharged.
  • Sewage treatment plants are modern technology which is reliable and extremely efficient.
  • Low running costs which offset the higher cost of installation.
  • Installation is simple and easy, though it should be done by a professional installer.
  • Whilst septic tanks and cesspits can reduce the resale value of your property, having a sewage treatment plant can make it worth more.
  • The system is compact and does not take up much room. Being underground, it will not impose on your outdoor space.
  • Alternatives such as septic and cesspits pose a number of potential dangers including gases, flooding and pollution. Sewage treatment plants are far safer in comparison.

How Much Does a Sewage Treatment Plant Cost?

Sewage treatment plants are used in commercial and domestic properties when access to mains drainage is not possible. They treat water to make it suitable to be discharged into a drainage field or watercourse.

Cesspits and septic tanks have a number of drawbacks, including potentially dangerous gases being released, pollution and complications when trying to sell the property; most home and business owners are making the switch to sewage treatment plants.

These plants are more expensive than a cesspit or septic tank, but they provide superior performance and mean that you can safely discharge water from the plant once treated.

In this blog post, we will examine the costs of buying and running a sewage treatment plant at your home or commercial premises.

Benefits of Sewage Treatment Plants

A sewage treatment plant is robust and extremely effective, offering many benefits over other methods of treatment and disposal:

  • Sewage in a plant is treated to a safe level
  • Does not harm the environment
  • Reliable and modern solution
  • Cost-effective over time
  • Compact system
  • Improve the resale value of premises
  • Safer and poses a lower risk to health
  • Simple and easy installation

Above all, these plants are a solution for the future. As environmental agencies impose stricter rules on the process of treating and disposing of wastewater, a proper biological wastewater treatment system ensures these standards are met.

Cost To Install and Supply

The cost to install a sewage treatment plant will vary depending on a number of factors such as the size of the tank, the condition of the site and any additional extras you may wish to have installed.

In domestic premises, prices start from £2,000, subject to the size of the sewage treatment plant. The price of installation will vary, and a site survey is generally required for an accurate figure.

Additionally, the price will be different if you are replacing an old system or a different type of sewage disposal unit or if you are installing one from scratch.

At Mawdsleys Pump Services, we design sewage treatment plant systems to meet the exact needs of our clients, meaning you don’t pay more than you need to for a plant that meets your needs.

Additional Costs To Consider

As well as the initial cost to purchase and have the plant installed, there are other additional costs after installation that should be considered:

  • Annual Service – An annual service is essential to the ongoing performance of your plant and reduces the risk of breakdown. An annual service starts from just £350 in most cases, subject to equipment and location.
  • Emptying – Once the sewage inside your plant is treated, it will need to be discharged. When it is emptied, there are costs involved, including contractor fees and tanker charges.
  • Discharge Consent – In order to release sewage from the plant, you must first apply for discharge consent and will incur a fee for doing so. At Mawdsleys, we can help with discharge water testing and can also acquire discharge consent for your unit.
  • Repairs – In the event of damage to your plant, fast and professional repair is critical to ensure that you can use the facilities in your property once more. At Mawdsleys Pumps Services, we offer a 24/7 emergency pump breakdown service.
  • Power Costs – As sewage treatment plants require a power source, you will incur a cost to run the unit. However, modern units are extremely efficient and use a small amount of power to run.
