What the hell is this pipe?

[southcoastboile]

Hello. Please could someone help me out with this pipe. We have showed it to 3 local merchants who suggest using other plastic pipe that's not the same make. I don't want to do this its on an unvented system and if it blows off its going to cost me a bomb so that's out the question but no one seems to know what the pipe is or were I can buy it.

Poly fit.

Hep2o will swap.

Are you sure it will be okay? I'm always worried about mixing and matching fitting makes. If it blows off I won't have a leg to stand on for the sake of a £100 job?

Will be fine

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

As above i'd use a good quality deep compression fittings to change from one to the other but you'll need the inserts for that
