Hi Guys, is anyone on here a plumber / heating engineer? I'm after some advice...
We had three radiators drained and removed so we could get our hallway and living room plastered. Plasterer has done a great job, but myself, not so good. I've just put the rads back on and sealed them all up. I've come to opening all the valves and seems I've probably over tightened everything and it's all made of moon cheese.
My master drain valve bolt has sheared and one of the lockshield valves has done the same. Luckily the drain valve has sheared closed and the sheared lockshield valve is closed too and I've only refilled the rad at the master drain.
As I see it I'm going to need the master drain valve and lock shield valves replaced, but as the drain valve is sheared I can't see a way of draining the system before replacing these.
Is there anything I'm missing that means I can do these without flooding the entire house with black filth? Or will I need to drain the entire system into a jug at the master drain valve by draining the radiator in the messy way there? Am I best off sucking it up and hiring a plumber to do this and hope he can sort it out without ruining our wooden flooring? We could do with getting the heating on quite soon as the house is condensating badly from the new plasterwork...
FYI, if it makes any difference it's a worcester combi boiler on a sealed pressurised system (I think).
Any advice or help to fix my cack-handedness would be massively appreciated.
Cheers
