Hi
I've just had a new combi boiler installed. I have recently noticed the pressure dropping gradually - it has dropped about 0.2 bar over a 3-4 day period. this happened when we didnt use the boiler for 3 days and also when we used the boiler for CH and hot water for 3 days.
The pressure used to stay constant at about 1.2 (the level it was filled up to) when the system was cold but now it seems to fluctuate between 1.2 and 1.
Is this normal? Or will this loss of pressure gradually get worse and fall below 1?
today is the 4th day running the central heating since we started keeping an eye on the pressure. We will see if it drops below 1 after the system cools down.
Having read some of the posts on this forum, we have checked for leaks in the obvious places - rad valves, prv etc. Cant see anything wet.
Thank you for any light you can shed on this.
