Ok working at a church, job was to change 32 thermostatic radiator valves.....easy
change a few taps ok.....easy
fix pressure drop on boiler.....not so easy
the boiler house is situated about 6 metres away from the church so the pipework goes under ground and then into the church.
pressure drop is pretty much top up to 1.5 in the morning by night it's sitting at zero.
Done the obvious things, checked pressure on expansion vessel which is all good
been under all the floor boards in the church all bone dry
checked prv over night with container under again that is fine
i then isolated the flow and return under the floor boards when it was entering the building so I was only testing from boiler to church under ground pipework and again pressure down at zero so I can pretty much rule the church out completely
not sure why I am writing this as I think I know what is required but just in case some one has any other suggestion thought I would come on here.
am I faced with the sad fact that we are ripping up the concrete base outside and digging to the pipes? No leak on boiler, no leak on prv, expansion vessel fine but there's a pretty major leak somewhere and that's the only place it can be......right?
