...SWMBO has been on for a while about getting a radiator in our bathroom, so during some other work I had a plumber doing they put the tails in the bathroom ready to take the radiator (needed to tile before it went on which is why he left it at that).
I've come to drain my heating system to fit the radiator and I'm struggling. I've got a retro fitted heating system (ie after the house was built, house is circa 1958). Heating system is about 5 year old I think, but I've only moved in a year ago. Anyway, it's a back boiler and I've got a cold water expansion tank in the loft. I've also got an immersion heater in a cupboard upstairs.
From what I've done in the past (and read on the 'net) I've stopped the header tank from refilling and I found two radiators downstairs with drain valves on, and opened both of them, and not a drop came out. :-/ Not sure what to try next. As it happens I've already taken off every other radiator upstairs, so there shouldn't be much water up there. They were pretty sludged up. I figure that the downstairs radiators are the same way, and perhaps the valves are blocked up. Not knowing what to try next I thought if I emptied enough water out the pipework upstairs then perhaps I could get away with fitting the new radiator anyway, so I started draining water from where an upstairs radiator used to be...
I've probably drained about 20-30 litres of water now, filling a bucket slowly and emptying each by hand. If the header tank isn't filling, the water to the house is now turned off, taps opened and nothing coming out, hot water tank empty, boiler switched off, water pump switched off... where the heck's the water coming from?!!
Anyone offer any words of advice (that don't involve ringing a plumber?!!!!!)
Thanks in advance!!!!!!!
