1st fix in large barn conversion

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

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

Get yourself over to Yahoo groups and get on UK_Selfbuild. They can help enourmously with your conversion. Firstly get it superinsulted.
