[quote="darrenblu"]I have a radiator which i need to remove so i can decorate. My problem is that i only have one valve and on all the info I can find states that ther should be one on either side. How do i drain it because when I turn the one valve off ther still seems to be water pressure, Ive also tried turning off all the stop valves i can find in the house. Your help would be much appreciated.[/quote]
Realise this is a bit late but only just seen it, you probably have what is known as double entry, or twin entry radvalves, you will have 2 x pipes connected to the same valve at one end, these valves are a bad idea hence you dont see many of them, to take off the Rad you have to turn off the control valve which you have already done, and next to this is on the valve is a small round cap, unscrew this and it will reveal an allen screw ( M8 I think) using suitable allen key screw this down in clockwise direction and Rad should now be isolated, to check open airvent first and check no water is coming out ( wait for at least 15 seconds and importantly close before next step) if this is ok undo the nut between Rad and valve and water will escape of which you have to try and somehow catch, you wiil find inside the rad a long length of 10mm? pipe which is comnnected to the valve, recconect when refitting the Rad.
My advice is Alter your Radiators to 2 x seperate valves and Buy some Radclamps for the future this makes taking off Rads a doddle with no mess. Good luck.
