Hi all, thinking of fitting the said isolator to my heating system from boiler to circulation pump in 22mm copper, so I can fir a MagnaClean Atom ( I know the position of the MagnaClean is not ideal but the return to the boiler runs down the living room wall within boxing in). I would normally drain down the system if I had more time to deal with airlocks upon refilling etc BUT with work at the moment I haven't! Looking on Aladdins website they give a good account of why not drain down your heating system, but I was wondering if anyone has used these "live fit" valves in the past and had any problems with them.
Cheers
