Thanks for that, what's the answer then from the man who knows.

System flushed 3 years ago, new inhibitor every 12 months since and no probs before. Valve is a LLandis and Gry dated 1998 replaced when I moved in then. PS It is a microbore system!!

Thanks for replys, didn't do it this morning HW only. Change the valve it is then?

Hi there I switched my CH on for the first time since the spring two days ago and it worked fine. Now I noticed that when the HW is on but the CH is off the CH still comes on ...weird. Can somebody offer a solution? Many thanks Guy
