Sometimes wonder if I'm doing the right thing or wasting my time trying to get everything done in copper with anything not accessible soldered? Copper seems to be getting more and more expensive as well as folk moving to plastic. Copper is great in visible areas and under sinks etc Dafty, but plastic is great under floors and through stud walls and has less movement through expansion so less creaking through the joists. The main player with it is speed, you can first fix a building in no time . Might give pex a go on my next big (for me) job where I need a fair amount of pipe runs etc. Still might worry about the push-fit blowing off under the floorboards. I've got a good cutter for waste pipe - the kind that cuts it with a blade. Could I use that on pex? Also are you supposed to use non-barrier on drinking water? So you gotta use different pipes for different jobs? |

So you gotta use different pipes for different jobs? If your cutter cuts the pipe square, then yes. You need a square cut & always use an insert. I strongly recommend Hep2o tube & fittings, it’s the best of them all, also buy a demounting tool & learn how to use it👍 |

You can use these on heating or drinking water Dafty. As Dick pointed out Hep is king for plastic (JG close 2nd ) and always cut square and remember your inserts mate  |

I’ve a mixture in Puller Towers. For boiler swops it’s all copper. On New Builds all PF, but anything exposed is copper. On Flats, any exposed Gas Pipes are Screwed steel pipe & fittings. New Builds can also have Gas Tubes in plastic coated soft copper run under concrete floors, in large plastic ducts. |

Yes, I would always advise people who want to use PF without worrying to follow the rules. Always use PEX barrier pipe on heating. Use a proper plastic pipe cutter with sharp blade to get a clean, square cut. Use the correct inserts, ie. for JG Speedfit it's Superseal inserts with the two rubber o rings when using pushfit fittings, or the JG plain/no o rings inserts when making a compression joint. When joining to copper be really careful that the end of pipe going into PF fitting isn't damaged, scratched or distorted in any way. Follow the rules and no need to mop up!
