15mm copper/plastic coupling
I have just been fixing a leak where copper pipe was joined to plastic
(polyplumb barrier pipe). For various reasons I chose to use a plastic coupling. Is the copper pipe/plastic coupling satisfactory long term? It is working fine as I write but soon it will be buried under the bathroom floor and everything re-decorated I don't want to have to rip it all out again. (I am aware that I could have used a copper coupling and a metal insert in the plastic pipe I just wonder if I "should" have done it that way round.) Frank the tentative plumber |

Plastic pipe in plastic coupling doesn't need any insert. Otherwise my new bathrooms fcuked :-( MBQ |

It won't leak straight away, but the pipe will go oval over time and you'll get leaks. What idiot told you that you don't need inserts? Hmmm. Any Hep2O fittings I've used had had metal pipe inserts used as per instructions . Stuart |

I actually used copper pipe with plastic fittings, that's why I didn't use inserts, doh. I think I can breath again. MBQ |

Presumably you used a plastic insert? -- Grunff Yes, I did use a plastic insert on the all plastic side. My worry is about the long term effectiveness of copper-in-plastic versus plastic-in-copper. So far I haven't seen anything which mentions this. Possibly because it is a non-issue - they are equally durable. Frank the tentative plumber |

The message
from "Frank Stacey" contains these words: My worry is about the long term effectiveness of copper-in-plastic versus plastic-in-copper. I did some a decade ago and they're fine. -- Skipweasel Pay no attention to the man behind the curtain. |
