Leaking radiator on which I closed the valve

[jtsplumbing]

If it's just dripping out slightly will be fine if it's spraying out all over the place need a new valve or cap it off

The only guaranteed way is to either replace the valve or cap it off

Right well anyway BINGO. Thanks man. OK so no need to undo the nut or remove the valve. Just this. I hope this simple solution works! It's £8.50 on Ebay. This means you're saying that pressure is NOT an issue, right?

2 x compression caps will cost a lot less than £8.50 and as long as you drain system very easy to fit, anyone with some common sense & a couple of spanners can do it

Op doesn't want to drain or freeze the system

Well it's a constant drip rather than spray. I have tied a cloth around it for now. I'll get some of that special sealant you showed me and see if it lasts. And make a note that if it doesn't the next step is a bit more radical and may cost me a week's money because, from what I gather here, either of those jobs could be more than I can handle. I thought you meant originally that it was simply a case of removing one valve and replacing it. Those ones on the left only cost a fiver on Ebay. I guess one can find the solution in a forum like this and then look for actual directions on YouTube or somewhere. Thanks for your sane advice and clarity. The internet eh?

have to leave it leaking then ! He's just after a free repair off someone, claims to have no money but can spend £8 on eBay.

P923.4 Stop End 15mm 2 Pack

Pair of end caps. Take it apart and use threaded end to screw onto pipe where your valve is. Would need to drain system or some of the water to be able to remove valve.
This may be handy
Good luck

Sounds like this is the ideal solution. I've ordered a tube of that Evo-stick sealant now and understand that this should do the job. I plan to place the plastic cover back over it to make it snug. That can always be cut off later if necessary. I'll keep this info in case it doesn't work! Cheers.
