Is there any good reason why the solvent-weld & push-fit pipes with
the same nominal diameters have different real outside diameters?
(The only reason I can think of is so they can sell more pipe whenever
you switch methods.)

Not 100% sure, but I think the pushfit ones are same diameter as
standard copper pipe sizes, to allow some interchange with copper
pipe and fittings.

Soldering them must be interesting. ;-)

The pipe size is based upon the bore, so different ODs mean different
wall thickness. To me, that suggests that the thicker (at least up to
2"/50mm) solvent weld pipe is rated to a higher pressure than push-fit.

Oh, that would explain it. (I guess there's no point in having the
pipe rated much higher than the pressure that will pop it out of the
push-fit.)
