The above boiler was fitted in current property approx. 4 years ago when new - and I have recurring leakage problems regularly.
It either 'dumps' directly under the boiler or/and projects water (with system presssure I assume) approx. 12" to 18" in front of the boiler soaking the carpet.
Just last week I called out plumber under service contract and he fitted new gaskets in bottom manifold? I think, but the pressure has started falling again and tray I have located under boiler has started to fill slowly with water again.
The thing is I have never witnesssed the leakage and I never see any evidence of leakage ie water on pipe threads/ on pipe or drips, although I realize the heat may evaporate this.
Is it possible that there is some sort of blockage and at a certain pressure there is
