Hi all,
A while back we had an issue with our boiler that was covered under warranty. The engineer that fixed it said our mains water pressure was too high and recommended a PRV to be fitted. I bought a gauge and it was reading 13bar, so I fitted a PRV just after the stop cock and set it to 5 bar. However, when checking the pressure on the PRV in the morning it often says it is over 8 bar (off the scale). I read somewhere that a PRV can cause high pressure due to not allowing pressure back to the mains due to temp increase in pipes. So I have now also added a 6 bar pressure relief valve aswell, however the pressure reading on the PRV still reads off the scale in the morning or when I turn the hot tap off quickly. Is there anything else I can do or look at changing?
System is a Worcester bosch combi boiler.
Cheers in advance
