I know psuhfit and solvent weld are different OD's for the same
nominal size.

What are the actual pipe OD's for pushfit and solvent weld? (32, 40
and 50 mm nominal)?

The installed "40 mm" 1 1/2" push fit here is contradicting the web.
It's old (25 years ish), have the sizes changed since then?

Try this table Dave:

I do not know of any change over the years, but then I've only really
used waste pipe in anger in the last 10.

Is there a specific problem you're trying to solve?

I had to replace a bit of pushfit waste pipe, it must have been
originally installed in cicra 1990 when the kitchen was installed in
this house.

It fitted the old fittings fine.

That's the bit of web that the pipes here are contradicting. B-)

The pipe I have is marked "... Extrusions Polyproplene 42 mm =" the
fitting are push fit, the pipe measures 43 mm OD and is polyprop.
According to that table 43 mm OD should be solvent weld, polyprop
isn't solvent weld able...

Is there a specific problem you're trying to solve?

A leak! In fact since I started disturbing things make that 3 new
leaks but the orginal one has stopped. However I'm not convinced it
was leaking in the first place as I just found enough condensation on
the pipe at that point to form a drip. Still I have removed the "dead
rat" from the bath bottle trap which was slowing the flow some what.

If some one can take a set of calipers to modern push fit and solvent
weld pipes it would be appreciated.

In that case, how about a universal joint - they will fit anything of
the same nominal size?
