Pressure dropping on combi boiler

Tech_Man · 14 Sep 2005

Hye

I have a combi boiler and have a problem. Every now and then i find that the pressure drops on the boiler and it turns off. I then have to refill the boiler and then the boiler kicks back in. Does nayone have any thoughts and even a solution on this problem?

Any help appreciated

I can't check at the moment as I'm at work.

I'm pretty sure that there are no leaks within the pipes

I'm not sure if the prv pipe is dry

Could you give me your views on both, whether it dry or not

Blow off valves prone to drip that's the problem if it drips constantly whether system is on or off. In which case expert can put new valve on or just new head or clean old valve, or in first place can get your system steaming hot and open it up to see if the blast of hot water cleans of debris sufficient to get it seated again, vaeign hope but wlays worth a try.

If water gushes out when system is hot you need to get the expansion vessel seen to.

If no water is or has come out you have a leak.
