Tecky dude, whats a PRV? nightmare is this boiler.. May sound daft, but if they move it from wall, can they put it back there, as apparantly new laws state you have to have em moved if going out into a passage......
Eyup. a corgi man can Xmas eve and said it was the PCB. So got one of those and it worked. So now have hot water & GCH etc....
However the pressure keeps going up AND down.... Up- water ****es out of blow off pipe thingy (i know- im not techincal) and down- heating turns...
please can any one help?
My pressure has been rubbish of late, and kept having to top it up.. After A few days i checked and noticed water gushing from by the pump... the coil had come off and pin with it.. . i reattached it, but boiler wouldnt fire up... Topped up pressure, bled rads, pump...
