Hi
I am losing about 1 bar of pressure a day on my heating system. I have read loads of posts with suggestions about what the problem could be. There are no obvious leaks although unable to check hidden pipework but no obvious damp patches etc.
I have tried to check whether the pressure relief valve is the culprit but looking at the boiler the condensate pipe disappears into a wall behind the boiler, along with the gas inlet pipe and I cannot trace where it then goes. There is nothing on the external walls of the house except for the flu. I suspect the condensate pipe goes into the internal drainage somewhere.
Anyway, I took the front panel off the boiler and the condensate pipe goes into what I have identified from a parts diagram as the anti syphon trap within the boiler. The trap is split into two sections. The one on the left was about three quarters full with the heating off. Upon firing up the heating this then slowly filled over the course of about a minute and then quickly emptied and started slowly refilling. From empty to full took about 5 minutes and then it emptied again. I cannot say where the water went, (ie down the drainage pipe) but the left side of this anti syphon tank does have the pipe coming out the bottom and disappearing into the wall behind.
So the question is, is this normal or is this a sign of the pressure relief valve being faulty?
