Common Booster Pump Issues We Resolve in City of London
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 City of London.
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 City of London 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 City of London ends with a written report, photographs and a fixed-price quote for any follow-up work — no drip-feeding bad news.
