Leaking radiator drain valve leaking

CBW1982 said:

I think I get what you mean, but just to be safe:

Turn off TRV other end.
Undo nut circled blue
Undo drain off tail circled yellow
Wrap PTFE tape around thread of new tail and insert into radiator
Undo nut circled red
Tighten nut (circled red) onto new valve
This is where you may need to push plastic piping towards radiator
Tighten nut (circled blue) onto thread of new valve
Open TRV and hopefully then start to fill up

Thank you very much for your reply.thxts very helpful.
The new valve is from BQ, everywhere else was closed. Will it be satisfactory. Also, the new drain valve has a separate tail from the valve. At first I thought, how do you screw this in, there is no outer nut. But when I disassembled it, I noticed that the bore has a hexagonal shape to it. I presume this is how it is screwed tightly into the rad. I don't have Allen keys large enough. Would Screwfix sell a tool for this application. If, what would it be called? I've seen this, but it doesn't really state in detail it's use. Or size.

Sorry, loads of questions I know

Thinking about the pushfit elbow. Assuming that is what it is.

Can it be disassembled? If so, how?

I was thinking, just in case I need to shorten the white 10mm pipe to better align with the new valve.

Yes it looks like push fit, just push the white ring towards the elbow and pull the white pipe. You should be able to reuse if not damaged. There maybe enough on it to push it in though, probably only needs about 5-10mm.

Thanks everyone
I'm off to bed
I'll probably be in touch tomorrow. Haha
Thanks again. It's much appreciated.

Hi all
Just a quick update

All adaptations, repairs and replacements successfully completed.
C/H system up and running well. No leaks. Good system pressure.
Even risked cleaning out the Magnaclean whilst the system was drained. I write "risked" because I always expect everything to go wrong when I have plumbing jobs around the house to do. Haha.

A big thank you to all who have contributed to my various posts.
It is very much appreciated
