The message from Lobster contains these words:
It's a straight pan connecter running into a sawn-off piece of solvent

filling solvent cement has been liberally applied!

Don't see what problem is - the white pan connector should pull straight
out of the grey solvent-weld pipe, and can be replaced. What's the
point of changing the grey pipe, as you seem to be suggesting?

I think he's thinking the connector's been somehow glued to the pipe. At
first glance it does look like that, but on close inspection I reckon
what appears to be a ring of solvent-weld gunge is actually the chamfer
on the pipe.

I can't see a chamfer on the pipe, it looks as if it's just been
sawn off straight. The gunk at the top could be - erm - well -
just some sort of gunk, I suppose. The OP will find out sometime.
