Plumber did it for me for 50 cash, including the new valve. It was an upstairs radiator. He said if it was downstairs he would have had to drain the whole system....much more expensive
you may have a DOC(drain off cock) at boiler or fitted to downstairs rad. looks like a little tap where you can attach a hose. There will be one at the cylinder. This is not the one you want .
Cheers for that Davyjones.
I will stay away from the hot press where the hot water cylinder is.
I will look this evening.
The gas boiler is in an external outhouse to the back of the house.
besure and close vents when you refill, once system is refilling, vent rads, check work for leaks, turn on boiler. heat to all rads, job done.
Good Luck.
Sorry guys, I couldn't find the drain cock valve....are there any other forms or types of valves that I should be looking out for to drain the system.
Is it possible to drain the system by bleeding the radiators down stairs with the upstair radiators bleeding points open.
Any plumbing merchants. Chadwicks, heat merchants etc. Expect to pay €14-ish for a TRV pack. 1 TRV and 1 lock shield vavle.
