Please can someone help with a problem that is driving me mad!!
I have a Ferroli combi boiler which is losing pressure.
It has had the expansion vessel checked, is not losing water from the prv and has recently has a new aav. It will lose pressure from 2 bar down to 1 bar overnight occasionally.
I will then top it up and pressure may stay unchanged for a week but other times will fall slowly over a week.
I assume it is a leak but why would pressure loss fluctuate like this.
Could it be anything else ?
I just need to be sure as the pipes are all under concrete floors!!
Thanks for your help
