Hi,
Over the past few months Ive had to top up the pressure on the boiler on a fairly regular basis,Ive checked the valves etc and can find no sign of a leak.However today on checking I found the pressure has risen! Anyone an idea?

Chances are either the filling loop is passing or the expansion vessel has gone. Is there any water coming from the pressure relief (overflow) pipe outside?

Paul

Paul,
There is no sign of water overflow as far as I can see
