Hello,

Just curious to know why pushfit waste and solvent weld waste have
different external diameters?

Is this deliberate so that you can tell the two apart and don't try to
weld unweldable plastic?

Or is it just a coincidence?

Would life be simpler if both were the same size?

Thanks,
Stephen.

Yup basically.

I suppose if you favour pushfit then it would, however it would be a
right PITA if you were using solvent and kept finding joints that would
not weld.

The problem comes when you have to join pushfit waste and solvent weld
waste. IIRC the only way to do that is with a compression joint and
some of those have ridiculously big nuts, which can't fit in tight
spaces under floorboards and other awkward places.

Fittings are made for the coversion I've seen them in the Warehouse B&Qs

Also the rubber collars that adapt CI soil stacks to PVC also come in more
modest sizes they have jubilee clips. They would be scarcely bigger than
the pushfit joints.

BES have universal pushfit couplers that will mate with either:

Thanks, I'll check those out.
