Ideal Combi bolier. When I repressurise the system to 1bar it almost immediately dumps the water out the condensate pipe before even switching in on at mains. HELP!
The only way your top up water is going anywhere near condensate is if your heat exchanger is leaking and even then it would take a few days to lose that pressure. You are probably talking about pressure release pipe not condensate pipe..
They are aliminium and for his top up water to straight go to condensate trap it would have to have a serious crack in it which is something i've never seen.
I still think he means prv pipe
