Another combi boiler losing pressure

[MANDATE]

Pressure rising by 1bar is about right..
I would however lower the water pressure to about 1bar so the rise would take it to 2bar.
If the 1bar pressure is maintained overnight, it would suggest the prv is doing its job.
If not replace it.

Ok Andytw, I see what you mean. I shouldn't have raised the pressure to 1.5bar

Correct, and we are talking about when the system is cold.

MANDATE, thanks for your post. The pressure seems to be holding. I'll lower the pressure to 1bar now and check again in the morning.

Sure, the system is cold now so will reduce the pressure now. Thanks.
