Many thanks for the information. Will give it a whirl. Appreciate your advice. Merry Christmas! and best wishes for the New Year.

I have a Sime Halstead combi-boiler (with no instructions). Boiler pressure reaches 4 bar when in heating mode, but the pressure release valve leaks at just under 2 bar, thus requiring constant top up to reach standard 1.5 bar pressure. Can anybody offer a suggestion to this problem? :cry: mjack
