A few weeks ago water pressure inexplicably shot up from 2 to 4 when boiler was on. Usually the pressure does not go above 2 when on. Had to get engineer out. He drained it back down to 1 (usual cold setting) and could find no fault, he suggested it had been over-pressurised, which I know for sure it hadn't.
A week later, the boiler stopped coming on. They came out again, this time it was a pressure switch that was faulty, a thin narrow tube which he blew into, lo & behold the boiler came back on. He said this had nothing to do with the raised pressure the week before. He also said the switch would probably need replaced, but I said I would monitor it. A week later, the boiler is not coming on again.
What I need to know is, is there a possibility the pressure gauge is faulty & this is causing false water pressure readings, in turn causing the pressure switch safety mechanism to stop the boiler from igniting. Or is the pressure switch faulty?
