Should be OK. Most of these things are uPVC. There is one breed of
wastepipe that is something else but it has a different BS number.

==========================================

Wickes sell two types of waste pipe - push-fit and solvent-weld. Would
one
of these two be the exception to which you refer? Cic.

The stuff I recall was plastic but copper coloured called something like
Bartol. It had a slightly slippery, soft feel surface and would not take
solvent weld cement. It might have been push fit. I 'inherited' odd bits
of it abandoned when I bought the house in the 80s.

upvc is a bit harder and you can't scratch it and make a mark with your
fingernail

Bob

A bit of googling reveals the consecutive BS numbers that I recalled.

BS5254 now replaced by BS-EN1329-1 is the upvc solvent weldable stuff
BS5255 now replaced by BS-EN1451-1 is the Polypropylene stuff which indeed
is designed for push fit.

==========================================

Thanks for that - I'll check those numbers on the stuff I'm using in the
morning. I need to do a bit of 'mix and match' and I've been working on
the assumption that the solvent weld stuff can be used with push-fit /
compression but not the other way round.

Cic.
