The JG speedfit is in my experence the most springy. I have never used Equador. I have used Hep 2O and PolyPlumb. They both seem easier to use than JG.

The difference is very marked. The 15mm PB stuff will nicely follow a

You must use the same manufacturer for the end supports as for the pipe. IME the PB pipes use stainless steel supports which offer less resistance than the plastic ones from JG (and others).

I've not had an issue with the flow resistance of plastic pipe relative to Cu.

Thanks all. Very helpful. I'll be opting for the Hep2O.

Thanks all. Very helpful. I'll be using Hep2O.
