Hi All,
My first time posting on this site, however am hoping that someone might be able to assist with an issue we are having with our boiler.
For the last 3 weeks we have been having to repressurise the system as it was losing around 1 bar every 8 hours, which was resulting in an E118 code on the boiler.
We've had a couple gas engineers look at the boiler, and all have said it is fine and the issue is a leak in the system.
We have also had 3 plumbers around, none of whom could find a leaking valve, so have indicated it is likely we have an under floor leak happening.
Finally we have had a specialist leak detection service out, who believe that they have found the leak under one of the raditators and so we are going to get a plumber in to pull up that section of flooring and fix.
So far looking like everything is going to be working again.
However...
When the specialist leak detection service came they drained the entire system to pump gas through the system to check for possible leaks, and then afterwards repressurised it.
Since then the system has been sitting on 2.3 bar pressure steadily, and now we have the opposite problem as when the heating is on the pressure rapidly rises to 3 bar, the PRV seems to activate and the boiler shuts off and has an E119 code (high pressure).
I was wondering whether it might be possible that the low pressure issue is actually due to an issue in the system, rather than a leak, and because the system has been drained this has reset everything?
Is this a possibility and if so if we bleed the radiators to bring the pressure back to 1.5 bar would the problem come back?
Really stumped with this and ideally want to prevent having to rip up floor boards if I can.
Thanks for your help
