Combi overflowing

[mark/uk]

I keep having to top the water level up via the loop because it's overflowing outside why is this?

everytime i put water level up to 2 bar ish it drops - any ideas?

 

[corgiman]

the pressure relief valves is leaking

you should also check the expansion vessel

Its a Halstead ace 82, there are two nuts that hold the water pump in place it seems to be coming from the bottom.

I can understand the drop in bar pressure because of this but why the overflow? it rarely goes above 2 bar anyway.

Cheers, Mark.

Disconnect or turn the filling loop off properly.

Okay the bottom nut has being tightened and so far no leak (hopefully it will stay that way however the outside overflow is dripping not to fast but constant.

Why would it overflow if its only at 2 bar max?

Probably because when the pressure relief valve(overflow) has opened in the past it hasnt closed fully due to carp on the seating, best get a new one, and also as C M says, check the expansion vessels not boogered.

Is this a Corgi job (above) Chris?
