[QUOTE="Alser, post: 505787, member: 33467"] Appreciate all replies, did look under boiler again and there is indeed isolating valves, (4) off, that can be turned off using a screwdriver. So, would I re-pressurise up to normal pressure and then isolate all 4 valves ? Worcester will repair out of warranty boilers, cost is as of now starting at £298 inc vat, not sure exactly what is covered though, claim 91% fix first time as they carry most parts with them and if I could discount a leak from pipework would probably use them. There is definitely no blowoff from prv. My query is that I could understand a rad pipe leaking if perhaps it had been disturbed or knocked and pressure loss as a result, but loss now is substantial enough compared to loss previously so what would make a pipe fail so completely? I did have a suspicion that maybe the shower valve could be an issue as hot/cold feed is hidden behind a partition wall and has been pretty erratic for a while with tempereture fluctuating between too hot, then too cold, (non thermostatic valve). but put this down to failing valve. Is it possible that there is a hot water pipe fail and could this also be the cause of pressure loss in the boiler? [/QUOTE]
