    I haven't taken the floor up yet. It started with a damp patch on the ceiling over a couple of weeks and now it has started dripping though the ceiling.

    Assuming that it's been correctly assembled fully pushed home insert in place and pipe not damaged/scratched.
    If fitting has failed you need to check out polypipe guarantee.

    Thanks I'm hoping for a nail. Have had that before where the nail has held pressure then rusted and started to leak.

    All they will do is replace the fitting.

    Actually not! some years ago we had a 15mm grey poly elbow fail after around 3 months.
    Open vented system elbow failed over night large amount of decoration damage to ground floor plus carpets.
    When you looked at fitting in effect 3 of the grab ring teeth were missing.
    All costs (including ours) paid by polpipes insurers.

    So was likely it came out of the factory like that? Did they check to see if had been tested to 18bar. Apparently they can tell by how far the grab ring has bit in to the pipe.

    Was described as faulty manufacturing.
    We always pressure test test first fix even on small jobs.
