Hi,
my boiler and central heating system seems to be running fine. Plenty hot water and heating. However, every few hours there is a loud hissing/vibrating noise coming from the pump on the water tank, it sounds like a build up of pressure.
I have turned the boiler off and on and it stops for a while.
I have been told the pump might just need bleed but really not sure.
Any suggestions?
