    Hi.
    1st post so be gentle on a noob :)

    I am wanting to run 28mm Qual Pex polybutylene piping to the UFH manifolds and hot water circuits of my self build barn conversion.

    For various reasons I won't bore you with I have been advised to use 28mm.

    As some of the pipes will end up underneath the liquid screed (that will eventually encapsulate the UFH) I have decided to use plastic. I figure that if there are no joints to fail, then they can't fail, if you see what I mean.

    My question is this: Do JG/Osma/Hep2o fittings work with each others PEX pipe or do I need to buy the Yorkshire IMI tectite fittings that Yorkshire IMI recommend for use with the pipe.

    If the answer is that I can use the other manufacturers fittings, do I use the T66 insert for the Qual-Pex pipe or the inserts that go with the other manufacturers fittings?

    Thanks

    PS here is our self-build diary if anyone is interested. Bit out of date at the moment but anyway

    Use the pipe inserts of the pipe makers and use normal good quality brass compression joints that are normally used on copper pipes - they can be used on plastic by wrapping the olive with PTFE. Don't bother with the plastic push-fit fittings. They are generally more expensive anyway.

    Nice barn :)
