  • 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.

  • I don't think there's PFTE on either the interface from the pipe to the valve, or the valve to the rad tail. It feels to me that there should be, but then what the fuck do I know. If there isn't, then it needs to be a good fit, surely, hence the prep question.
