The pressure on my 4 year old Worcester Bosch combi is on all over the place.
It is reading 0 when the boiler is switched off and varies between 1 and 3 when switched on. I think the 3 may be because I overpressurised it! I wasn't sure what to do so went outside and I noticed that the little copper pipe that goes out through the kitchen wall to the outside had started dripping, every 3 seconds. I'm not entirely sure how much water eventually came out of it because it was dark and raining.
After a short while I noticed the pressure starting to fall on the pressure gauge and it went down eventually to about 1 and a half. Today pressure is again at 0, I haven't switched it on yet.
I'm now wondering if I have a leak in the radiators. Is it best to have the central heating running so the radiators are hot or is it best to check the joints and valves (or whatever your call them) when the radiators and cold?
I can't think of any other reason why the pressure gauge reads 0 when switched off.
Many thanks.
