About Wilo booster pumps
Wilo was founded in Germany in 1872 and is a long-established manufacturer of building services pumps, water supply systems, HVAC pumps and pressure boosting equipment. Wilo booster systems are often used where efficient pressure control and reliable building water supply are needed.
Where Wilo booster sets are used
Typical sites include commercial buildings, offices, apartment blocks, hotels, schools, healthcare buildings and plant rooms where a booster set is required to maintain stable cold water pressure across several outlets or floors.
Common Wilo booster pump faults
Typical issues include low pressure, unstable pressure, controller alarms, pump not starting, pump running constantly, short cycling, drive or inverter faults, pressure sensor faults, vessel issues, leaks and ageing pump components.
Checks before booking a visit
Photograph the Wilo booster set, controller screen, pump nameplates, vessel, pressure gauges and any fault display. Note whether the system is single pump, twin pump or multi-pump and whether the problem happens constantly or only at peak demand.
Repair, servicing or replacement
A Wilo booster issue may be caused by the pump, sensor, control equipment, vessel, non-return valve, isolation valve or wider system demand. Alton Pumps can help identify the best route: service, repair, replacement component or full booster set replacement.
