Hi
I recently drained my combi boiler to fit a new radiator. After the refill everything is working fine and I can find no leaks, but the pressure has been dropping 0.1 bar overnight when it's cold.
Is this normal for the first day or two? I read that these boilers have an air vent, so perhaps it's been venting air after the refill which might explain it?
Thanks for your feedback
