I have one of your water booster pumps fitted 6 years ago.

Customer Question

Hi. I have one of your water booster pumps fitted 6 years ago. It has always worked well but at the moment it is starting up every 3-5 minutes, even through the night when no water being used. I have a large water tank so can see supply water level and marked the level and monitored us when no water being used at all through the night. The level stayed the same but pump started and stopped every few minutes as mentioned. Any ideas if this could be a problem with the pump? There are no signs at all of any leaks anywhere in the water system. Thank you David

Good morning, welcome to the Technical section in JustAnswer. My name is ***** ***** I will help you today.

This behaviour is generally a symptom of a failing non-return valve on the pump inlet. You can test this theory if you have a good quality manual valve on the inlet, and you shut that off. If the pump doesn't cycle anymore then you'll know that water was passing by on the NRV.

Are you thinking of doing the repair work yourself?

I would like to do myself but have plumber looking at the problem too.

Ah, OK. Since you have a professional on the case, there is no need for me, so I will opt out.
