Thanks for help.Had an engineer round who replaced the pump (we are on a contract) Also the flow settings on boiler and pump were not right???
Maybe I heard that wrong as I am a total amateur.
Thanks again.
hello
I drained my system to replace a radiator valve and the boiler refuses to start.I have tried to get rid of any airlocks as the pump by the water cylinderb is running noisely.
Any ideas :idea:
Thanks
