[Help] HELP: Draining a radiator. What am I doing wrong?

[marlowe]

A friend has asked me to reaffix a radiator which has come away from her wall. To do this I need to remove the radiator in order to resecure the brackets.

I'm trying to empty the radiator but it doesn't seem to be emptying.

First I turned off the two valves (clockwise) on either end of the radiator.






Then I loosened the connecting nut to drain the water.



Then I opened the bleed valve at the top of the radiator.



However once I open the bleed valve a thin stream of water spurts out from a little hole in the bleed valve and doesn't diminish or stop which suggests water is still getting in to the radiator.

Can anyone with any plumbing knowledge advise. If I have turned both valves off fully why is water still entering the radiator? What have I done wrong?

Thanks in anticipation of some sensible responses together with the inevitable facetious ones.
(Ignore last sideways photo. Not sure why it's even there and can't delete)

probably one or both valves are failing? easiest way would be to drain the entire system, do your repairs then replace the valves (£10) prior to re fixing and refilling the system and bleeding the whole system, failing that toolstation/screwfix sell a freeze kit which you can freeze the pipes both sides of the offending radiator and hurriedly carry out your repairs. id drain the system personally. good luck.

Not sure they'll be too happy about all the red marker pen on their walls.

Whatever looks to be a simple job invariably isn’t ...ive text Simmo (explumber) if he sees it he may come on and give advice...all the best

Have you tried turning it off and on again?

inadvertently, not bad advice as the valves may have become sticky and by undoing and tightening a few times may result in unsticking the valves, a gentle tap may advance this also.

YAY! My work here is done!

I was waiting for that inevitable piece of advice. An advice thread wouldn't be complete without it.

Shouldn't that be former plum

Just asking the obvious, you have made sure the heating is off so the pump isn't running?

None of us are safe with you about

So it appears the fault isn't in my workmanship but in the radiator itself. I'll try [MENTION=205]Tom Hark, Preston Park[/MENTION] 's unintentional piece of good advice.
Would it be more likely the thermostat valve causing the problem?

Thanks. I did have him in mind when I posted. He's helped me out in the past with previous plumbing advice. I know he's retired now but hopefully that doesn't extend to imparting his knowledge and expertise on internet football forums.

I find it quite amusing that there is a thread on effectively leaks, not far from the Leicester match day thread

Ridiculous to suggest all that work for that improbable theory.
OP does the radiator go cold when the valve is closed? If so, how can both valves be faulty?

Freeze kits are only for people who know what they're doing and have done it before.

I agree. Not my personal choice but it was me who did that job too. Female friends without a man in their life can become very dependent, although I wasn't actually a friend at the time so was able to charge more. Now she expects mates' rates all the time.

Yes I believe it does but not absolutely certain. I'll have to check with her as I'm not there at the moment.
