I am having problems with constant water noise in radiators, have put on thermostst valves flushed out system etc. if I try to balance system I get Scretching noise and have to turn the outlet valve to the off position to stop the noise at the point it stops I have switched outlet flow off altogether.
I have a Bosh Worcester Boiler and I can't find anything in the manuel regarding slowing down the pump. Has anyone any idea of what I should do next?
