I'm going to be replacing my shower valve soon. I know the old one

reconfiguring for the new valve (basically, with the current valve
there are 90-deg elbow 15mm tap connectors on the feeds, and these
will need changing to straight ones.

I've never used plastic tube before, but AFAICR it's important to use
fittings which are compatible with the brand of tube, correct?
Particularly inserts within the pipe? I have no clue what brand mine
is (it's grey, 15mm) - maybe I'll find it printed on the pipe when I
have it fully exposed?


If it's grey, it is likely to be either Polyplumb or H2O, all but the
very cheap pipe (eg some white floplast) has this info printed on it.

John Guest also do a grey Speedfit pipe, but yes name should be on the
pipe, you could probably also identify it by the fitting design. either
by Googling up images or posting an image for others here to identify.

Thanks everyone all the info; that's reassuring. Hopefully when I
expose the pipework fully it'll be clear what brand I've got and I can
take it from there.

Cheers
