I'd like to change the 3 way valve on the central heating as the radiators are getting hot when just the hot water is selected on my gas boiler. (Valve sezied I'm sure of that)
I've been told I'm not allowed to do it because I'm not corgi registered ?
B****ks was my response, surely its plumbing [1] and a bit of electrics, I'm not touching the gas side of things anyone like to differ ?
[1] drain system, swap valve, refill system inc inhibitor, wire valve.
