I've never bothered looking too hard before, but have noticed my WC
pan connector (push fit 110 at the non WC end) had some quite
pronounced mould seam ridges down both sides.

On this I've carefully pared them off with a stanley blade, leaving a
slight groove (original defect, not knife related).

Happened to notice even the Floplast Tee 110 I have also has slight
(but not as pronounced) mould seam ridges.

Do people normally pare or sand these off?

I've not had any leaks before, but then my joints face the right way
and are never under pressure and I don't have the kit to pressure test
my system.

So this is just a curiosity "learning to do things better" kinda muse...

I've done it occasionally. I tend to fit these with silicone oil or
spray as they are normally pretty tight.

+1 I always use the spray - partly because I'll have the joint apart 20
times during test fitting, tweaking, fixing, boxing in - don't want to
knacker the rubber.
