We are the specialist booster pump service London team covering Barnet and the wider South East — same engineers, same response standards.
Our Barnet engineers are directly employed, DBS-checked and experienced on every major commercial booster pump brand — Grundfos Hydro MPC and Hydro Multi-E, Lowara GHV and e-SV, Wilo Comfort and Helix, DAB E.SYBOX, Stuart Turner StuartFlo and Aquaboost, Armstrong, Calpeda, Salmson and KSB.

Every job is delivered to the relevant UK standards — the Water Supply (Water Fittings) Regulations 1999, WRAS Approved Product schedules, BS EN 806, BS 8558 and the SFG20 maintenance task lists your compliance team audits against.

Common Booster Pump Issues We Resolve in Barnet
Low or fluctuating water pressure
Usually a tired mechanical seal, fouled impeller, flat accumulator pre-charge or drifting pressure transducer — all serviceable on the first visit in Barnet.
Pump cycling or hunting
Often a failed accumulator diaphragm or incorrectly tuned variable speed drive. We re-pre-charge, retune the cascade and prove stable operation.
Booster set tripped — no water
Our Barnet 24/7 line is answered by an engineer. We diagnose, restore supply where possible on the first visit, and rig temporary pumps if a strip-down is needed.
Noisy or vibrating pumps
Bearings, anti-vibration mounts and worn couplings are the usual suspects. We measure vibration, replace where required and re-align.
VSD / inverter fault codes
Grundfos, Lowara Hydrovar, Wilo SC, DAB and ABB drives — we read the fault log, replace failed transducers or boards and reprogram cascade settings.
Failed pressurisation unit
Mikrofill, Aquatech, Grundfos and Stuart Turner units serviced and repaired — including expansion vessel pre-charge and break tank inspection.
Every fault visit in Barnet ends with a written report, photographs and a fixed-price quote for any follow-up work — no drip-feeding bad news.
