My Ideal boiler pressure gauge pointer shows about 0.85 when cold (about 1.8 when the heating is on).
10 weeks ago the readings were 1.0 when cold and 2.0 when hot.
Clearly there is a loss in pressure over time. I can see no leak on any radiator or near the boiler. Is this pressure drop of about 0.1 bar a month normal or do I need an engineer to look at it. A new sump was fitted 10 weeks ago which is when I started watching the pressure.
Thank you for any advice.
