Hi,
Just about to plumb some waste pipe got all solvent joints and solvent but
when I went to go and get the pipe I found have two types of pipe one for
push fit and one solvent, however the solvent one seems alot more expensive
that the other. However in a few stores Wilkinson's etc they have pipe that
doesn't state if its push fit or solvent but is only a few pounds. Does the
pipe I use have to be specific for solvent joints or can I use any.
Thanks
DD

The pipe sizes for waste vary slightly from manufacturer to
manufacturer as well as between SW and push fit so I would use the
same make as the fittings.
There are some manufacturers that have compatible pipe sizes but from
memory I can't remember who's.

Generally the SW pipe manufactured to BS 5455 (IIRC) is interchangeable
but thee are slight variations between manuafacturers.

The push fit pipe is somewhat smaller (by a mm or two) and may also be
made from a plastic that won't SW.

It does have to be PVC or ABS. Push fit waste is sometimes
polypropylene and apart from being the wrong size, will not weld (at
least with the typical solvent used for the purpose).

Oh I ordered the SW joints from screwfix but wasn't looking at ordering the
pipe from them as they only do big packs and I only need a few. Anyone know
If the joints from screwfix are suitable for use with the pipe sold in
Wickes.
Thanks

It does have to be PVC or ABS.

Given the choice, PVC works slightly better than ABS.
Sheds mostly stock ABS (I presume it's cheaper).
A plumbers merchant will have PVC (might be marked
uPVC, or muPVC which is higher quality).

Push fit waste is sometimes
polypropylene and apart from being the wrong size, will not weld (at
least with the typical solvent used for the purpose).

Just finished a bathroom project at my daughter's and used Screwfix joints
with Wickes solvent weld pipe. Joints a tight fit dry but worked fine when
put together with the solvent.

I've had good results welding PP with a hot-air gun.

Admittedly this is useless for welding pipe in place, but it let me
make up a nice low-profile washing-machine drain and U trap to go in
a confined space up from bits.

You need to play for a while.
