no the insert should suit the pipe not the fitting you have got it the wrong way round spanner

Well that was the point I was going to make Steve, but I wasn't sure whether his "advice" was actually contradictory to this, due to it's general incoherency.

To clarify - The insert/liner must be the correct brand for the PIPE, due to differing inside diameters of pipe between brands. NOT the fitting.

Spanner.
Pipe sizes relate to the outer diameter of a pipe.

this means jg, polyplumb, hep and the other plastic fittings will work on each others pipes as they fit the same OD

BUT
They have different internal diameters which the insert goes too.

jg could be 14mm id while hep is 13mm.
you need the correct insert to stiffen the pipe or they sit lose and are useless.

Shall we make this easier.

Only use the same manufacturers pipe, insert and fittings.

Okay thanks. Now let's say you have a jg tee and a polyplumb pipe! The way round would be to use the polyplumb pipe insert
