Boiler: Worcester 35CDi
Problem: gradual loss of pressure
Suspected Fault: expansion vessel
The boiler runs fine but after pressurising it loses pressure over a couple of days, and eventually settles down to about 0.5 bar. At this point the rads. dont really get hot properly, and it is noisy
The leak is not from a rad. or pipework, but it is dripping from the overflow pipe outside. Thinking it was the PRV, I replaced it but still the same problem.
Tried pumping the expansion vessel with a bike pump, and seemed ok for about half a day. Some water came out of the valve on the expansion vessel when I took the cap off. Does this mean it is broken?
So the question: is it likely to be the expansion vessel at fault, and is that an easy thing to change (I am reasonably competant at plumbing).
Thanks.
