im no boiler installer but it sounds like your pressure relief valve is stuck open..what is your pressure gauge reading it should be no more than 1bar..lee

Cheerz bud, it was on 0.0 when i looked after the boiler tripped off, I filled it up but at 0.6 bar the water kept coming from the outlet, I`ve pushed/pulled the relief valve button and that seems to work ok? At the moment the boiler is on and working ok, but the water is still dripping from the outlet? strange

The problem is common with all combi boilers as the pressure relief valve is not design as a system drain and as such the valve seal is very easily compromised by debris in the water that comes out when it opens, bet you it is leaking still due to some crap caught under the sealing disc.

 

The reason why it opened needs checking though, is the filling loop connected all of the time but just valved off ? if so its possible the valve was passing a little and over a period of time over pressurised the system, this in turn opened the valve and now crap is caught under the seal.

 

 

The other possibility is the gauge is under reading so it was inadvertedly over pressurised, or maybe the equalisation (pressurised) vessel inside the boiler needs pumping up.

CheerZ Jeff, I think i have over pressurised the system by topping up and leaving the valve open over night!!oooppss, I will have a gander to see if i can get inside to the valve seal and clean it out, Thanks for you help mate

had this problem on mine, pressure kept dropping and allowing water out of the outlet when shouldnt,

 

it was the accumulator (spelling!), £312 quid later, it looked like a large heater matrix with twin inlets into it.

Does sound like the relief has failed so you will need another. remember the link pipe that you fill the system should not be left in the loop. Disconect it and put safe.

Cheers for all the help guys, Mr engineer is coming out tommorrow to fix the problem and probably empty my wallet :scared:
