What the hell is this pipe?

Doesn't look like PP to me.

Not PP. But PF. Think it's made by polypipe.PolyFit 15mm Equal Tee | PolyFit Pushfit Fittings

Use a compression fitting then. All manufacturers will accept compression as a transition between different brands.

As longs the correct insert has been used.. JG don't allow there super seal ones, it has to be the rigid ones

Don't John Guest say there speedfit fittings can be used on any pipe? Even if you get the correct fitting and it blows off, you wont have a leg to stand on and you will be claiming through your insurance anyway.
