    Booster Pump Servicing London

    Booster pump servicing across London and the M25 for domestic pumps, block booster sets and commercial plant rooms. Most booster breakdowns are predictable: a vessel that has quietly lost its pre-charge, a strainer nobody has cleaned, a standby pump that has not run in two years and has seized. An annual service finds all three while they are still cheap, and leaves you with recorded figures to compare next year.

    What our booster pump servicing covers in London

    • Annual and six-monthly booster pump servicing
    • Accumulator pre-charge tested and reset
    • Cut-in, cut-out and set pressures recorded
    • Strainers cleaned and non-return valves tested
    • Duty/standby changeover and rotation proven
    • Running current and insulation checks
    • Dry-run protection function tested
    • Written service record with all readings

    What a booster pump service includes

    A proper service is measurement, not a visual glance. We isolate and drain the water side of the accumulator to read the true pre-charge, reset it to the correct figure for the set pressure, clean the inlet strainer, test the non-return valves, and record cut-in and cut-out against the design set point. Each pump is run individually under load with its current measured and compared against the nameplate, and on twin sets we force a changeover to prove the standby pump actually starts and carries the duty.

    • Accumulator pre-charge read on a drained water side
    • Strainer cleaned, NRVs tested, leaks inspected
    • Set pressures recorded against design
    • Each pump run under load with current measured
    • Duty/standby changeover and rotation proven
    • Dry-run and low-level protection function tested

    Why servicing prevents most breakdowns

    Booster sets fail in slow motion. A vessel loses pre-charge over months, so the pump cycles harder and harder until the seal or the switch gives up during a peak. A standby pump that never runs corrodes on its shaft and will not start on the day the duty pump dies. A partially blocked strainer starves the pump and cooks the seal. None of these are dramatic in isolation, and all of them are picked up by a service that records numbers and compares them with last year.

    • Cycling caught before it destroys a seal
    • Standby pumps exercised so they start when needed
    • Strainer blockage found before the pump runs dry
    • Drifting controls corrected before pressure complaints start

    Service intervals and contracts

    A single domestic booster pump is normally serviced annually. Booster sets serving blocks, hotels, schools and commercial kitchens are better on a six-monthly cycle because the duty hours are far higher and the consequences of failure are worse. For multi-site portfolios we offer planned maintenance contracts with fixed visit pricing, an asset register for each pump, and priority response if a set fails between visits.

    Records, compliance and reporting

    Every visit produces a written record: pre-charge before and after, set pressures, running currents, changeover result, strainer condition and any defects found with a priced recommendation. Managing agents and facilities teams get the reporting they need for planned maintenance evidence, and you get a clear history that shows whether a pump is deteriorating or stable. Where a vessel or pump is at end of life we say so in the report rather than leaving it to fail.

    • Photographed, dated service records
    • Before and after pre-charge figures
    • Defects listed with priced remedial options
    • Asset register maintained across multi-pump sites
