5000+ Pumps Serviced

A commercial booster set is the heart of a building's water supply — and like any plant, it only stays reliable with regular maintenance. We provide booster set maintenance across London through one-off visits and structured PPM contracts, covering pumps, pressure vessels, controls and everything in between.

Maintenance clients get priority same-day response on breakdowns, a fixed annual cost, and a complete documented history of every asset — exactly what insurers, auditors and managing agents expect to see.

PPM Contracts for Booster Sets

Our planned preventive maintenance contracts are built around SFG20 guidance and the duty of your equipment. Each scheduled visit covers the full set: pump condition and current draw, mechanical seals, bearings, pressure vessel pre-charge, valve operation, control panel, drives, transducers and dry-run protection, followed by a full system pressure test.

  • Annual or six-monthly scheduled servicing
  • Priority same-day breakdown response for contract clients
  • Fixed annual pricing — no surprises
  • Full asset report after every visit
  • Pressure vessel inspection and pre-charge check
  • Control system and drive testing with recalibration

Pressure Vessel and Control System Testing

The two most common causes of booster set failure are a flat pressure vessel and drifting controls — and both are caught by routine testing. We check vessel diaphragm condition and recharge pre-charge pressure to specification, then test and recalibrate pressure switches, transducers and variable speed drives so the set holds its design pressure without hunting or short-cycling.

Maintenance for Every Major Brand

We maintain booster sets from every major manufacturer — Grundfos Hydro and CRE ranges, Lowara GHV and SMB, DAB KDN and NKV, Wilo COR and Helix, Stuart Turner MAB and Aquaboost, plus Calpeda, Armstrong and older obsolete sets. Where spares are no longer available we will tell you honestly and price a replacement alongside the maintenance quote.

Frequently Asked Questions

What does a booster set maintenance contract include?

Scheduled servicing of pumps, pressure vessels, valves and controls, priority same-day breakdown response, and a full written asset report after every visit.

How much does booster set maintenance cost?

Costs depend on the number and size of sets on site. Single-site PPM contracts start from £480 per year — we quote after a free initial survey of your equipment.

Can you take over maintenance of an existing booster set?

Yes — we regularly take over PPM from other contractors. The first visit includes a full baseline survey so we know exactly what we are maintaining.

Quick Answers

The questions people ask Google most often, with straight answers from our engineers.

How often should a booster pump be serviced?
At least once a year. Busy commercial buildings, hospitals and hotels usually have servicing every six months, in line with SFG20 schedules. A service covers pressures, motor currents, seals, vessel pre-charge, controls and alarms, and ends with a written report.
Pump maintenance contracts
How often should a booster pump run?
A healthy booster set only runs while water is being drawn, then stops once pressure is reached. If it starts every few seconds with no taps open, or never stops, there is usually a leak, a failed non-return valve, a flat pressure vessel or a faulty pressure sensor.
Booster pump fault finding
What is on a booster pump maintenance checklist?
Check suction and discharge pressures, cut-in and cut-out points, vessel pre-charge, motor currents, seals for leaks, bearings for noise, non-return valves, dry-run protection, break tank level controls, alarms and BMS signals. Then record everything in a written service report.
