AccuBoost SupportWe're here to help

An accumulator tank stores water under pressure to provide an excellent solution for properties requiring additional boost to mains water flow and pressure

The pump on an AccuBoost accumulator turns on when it recognises the system pressure has dropped below its activation threshold. The minimum pressure to activate the pump on an AccuBoost accumulator is 1.4 bar.

When an outlet, such as a shower or tap, is turned on the system pressure decreases. So if only a small amount of water is used, the pressure may not decrease by enough to reach the minimum pressure required to activate the pump.

If the pump on the accumulator is running on/won’t turn off it could mean that the vessel has not reached full water capacity and the pump is still running to fill. It could also indicate a leak in system. Allow sufficient time for vessel to reach full capacity (this can vary between 5-40 mins depending on vessel size) and check all outlets are closed and there are no leaks on the pipework.
