My boiler has been losing pressure. Please bear in mind I'm no plumber, so if I describe things badly or use the wrong terms I'm sorry!
It did the same thing a while ago-it would lose enough pressure to shut down-filling it with the filling loop fixed it for a short while (a few minutes), before the pressure dropped right down again. This was sorted out by bleeding the radiators, then the pump, then re-filling. This time these steps have not solved the problem.
Water is coming out of the PRV outlet. I have turned the PRV round a few times, but it's made no difference.
I understand these symptoms may indicate a problem with the expansion vessel, and that this can be tested by pressing in the valve to see if air or water comes out. The problem I have is that I CAN'T FIND THE PRESSURE VESSEL! Supposed to be a big red thing, but there's nothing like that visible. I've got the front off, and the cover under that off (so the only cover left on the main part is the one directly over the heat exchanger and gas bits. Still can't see it.
It's the same boiler as in this thread.
The only other thing I noticed was a load of cack around the bleed valve on the motor. Like deposits from water (we have VERY hard water here!), but it's dry.
Does anyone have any suggestions, other than 'replace the boiler, it's rubbish'?
