Hi, I have a worcester Bosch 350 combi boiler. It has started to drip from the overflow and thus loses pressure slowly over a few days.(it as only a slow drip). Has anyone got an idea what the problem is? All answers greatfully received.
Hello Keel,
Have a peek at my post and maybe we can come to some kind of arrangement ????
Hope you find help here.
When my system was losing pressure the bloke fitted a 'new cylinder' thing, sorry not sure about the cost, but it took him a few hours to do.
you should fill your combi back up to between 1 & 1.5 bar, do this when the boiler is cold. fire up combi, if pressure rises to 3 bar, you have a problem with your expansion vessel. this would cause p.r.v to lift thus crud could now be under valve seat
