Hi
I have a pressure activated hot water booster pump in my loft bathroom. It's worked fine since installation but after some recent repairs to the bathroom, it no longer works properly. It switches on when the hot tap is opened, but makes a loud dry rattling sound, and no water is pumped. After a while (a minute or few) it might kick in and then function properly, without interruption. Video here: https://goo.gl/photos/2KsLVVJJwf4LotLx7
Airlock maybe? Can anyone advise?
