Slack on pipe to fit new radiator

    Hi all,

    I need to replace a leaking rad so I bought a 1400 mm (Stelrad) in Baldoyle today. This one has larger fins placing the pipe centres just slightly further away than the old 1450mm radiator (about 4mm or 1/8" further).

    For some odd reason the pipes go directly into the plasterboard on copper which immediately right angles down to a connector (somewhere!) to the qualpex under the concrete floor. Short of it, there's just no slack at all. I'm not sure I could get 4mm but I'm unhappy about pulling too hard on the pipe.

    I'm wondering what you plumbers do in this case? I could look around for another rad with shorter fins (which seems a pain) or I could hack out the plasterboard and see what I can do with the piping... Not sure.

    Thanks.

    Actually, I realise the old one is a "round top" radiator and the new one is not. I guess the round top type are much less deep. Perhaps I should find a source for the same style as I have.

    could you post a photo of the existing rad valve and where it goes into the wall.

    Rad brackets can generally be fitter 2 ways one closer to the wall and the other slightly further away from the wall, using them one way or the other can some times work better, ie. leaving more room to modify pipework

    I feel a little stoneaged sometimes not having a digital camera :( It's just a valve with the pipe vanishing into some plasterboard. The compression fitting on the pipe is only a finger's width from the wall.

    Thanks - yes, the old rad is quite narrow so the current bracket is using its wide side to mount on (otherwise the pipe to valve fitting would hit the wall). If I use the narrow side on the new brackets, I get very very close, within a few mm. Because the copper into the wall bends downwards, I won't be able to haul on it without breaking the plasterboard (or worse, pulling the fitting off the qualpex somewhere).

    I did ask at the shop I bought the radiator from and they said "Well, life is never easy is it...". I guess that's about the size of it ;)

    If it doesn't fit, well, I'll just have to get more involved with breaking some plasterboard to get to the Pex connector. Sure I need to do that over the other side anyway as there's a leak somewhere so this'll be good training!
