[QUOTE="Geoff1946, post: 473156, member: 28452"] Oh, I didn’t intend to endorse the fault diagnosis, only say what the PR valve is for. I would bet on a wiring error, perhaps the valve micro switch switching it’s own supply or similar. I do believe a bypass is needed though as the pump will run on after boiler switch off to disperse residual heat. [/QUOTE]
