ISTR some mention of Plumbers Mait prone to 'growing' things and an
alternative to it - is there such a thing? Also, PM is a bit awkward as it
tends to stick to the wrong item (me!) and is difficult to get off - the
trick of rolling some of it works only to some extent.

I've also occasionally used Boss White in this sort of application, more
runny than PM and easier to clean off "cleanly". But typically on cheap
and nasty waste fittings.
