    Hi I'm redoing our ensuite and it's mostly plumbed with grey 22 and 15 mm plastic pipe .
    I'm not a plumber I'm an engineer and I've always used copper and soldered it with no issues .
    The dilemma I'm having is do I do all the plumbing with plastic pipe or do I do what I'm used to and use a speed fit connector and continue using copper for the 1st fix on basins ,bath and shower .
    What is everyone's else's preference ?
    Thanks

    Copper pipe was invented by the Romans (as was central heating) so it must be better than modern materials. In the same way that a horse is still way better than a car

    I think you meant lead. They took flat sheets of lead, rolled it up and soldered the edges together to form lead pipes. Lead pipes were still regularly installed into the early 20thC.

    Nothing wrong with plastic. Many plumbers who initially said they would never use it do now.

    I've used hep2o for a long time and they're still ok.
    Would it be ok in 50 years?
    Who knows?
    It all depends on what kind of rubber seals they used.
    Some rubber trims i see in cars and boats last half a century and are still like new.
    Some chinese rubber becomes brittle in 2 months.

    Yes, I think this is the key point. Which is why I use brass compression fittings whenever I use plastic pipe - no rubber to deteriorate.
