Replacing them is part of the long term plan. All but one of ours needed the worst of all the adaptors.
Ballcock? I don't know, hence the question. Will take a look at the tank later. It's in ms_com's office.
I've asked the plumber who fitted the towel rad to quote seeing as he's already done that kind of work here before. If he says anything less that £200 I'll probably just throw money at him. But it would be good to know how to do it if he comes back with more/is too busy.
The pipes are about crusty going into the old TRVs, what's the best way to clean those up/prep them for a good fit with the new ones?

It's a compression fit from the pipe to the valve, isn't it - why not wire wool & ptfe.
Cue teeth sucking & wincing faces from all the plumbers.
If you're draining the system, though, you may as well replace all of the valves - I did 9 in about 2 hours.

This is why I replaced all of our rad valves. The adapters are rubbish.
Don't you just raise the ballcock in the tank? I've no idea, to be fair.
