Leaking external 40mm waste pipe

[markwm]

The external waste pipe from our bathroom sink is leaking. Pipe is 40mm solvent(unpainted), been there a good few years...

Just looks like it has cracked a little bit on one of the elbows...

So, Silicone? Acrylic? solvent cement? or LS-X?

Why cock it up??? replace it, nice easy DIY project for you !!!

It's hard to replace as literally only 30-40cm of it is visible from it coming out of the wall into the soil stack and there's 2 elbows. Also it's not accessible from inside as it's behind the bath.

try it with some solvent cement.
is it grey or white plastic pipe ?

try wrapping exposed leaking 40mm in Denso tape
no pressure in 40mm pipe so should do the job

try it with some solvent cement.
is it grey or white plastic pipe ?

It's white(yellowed a bit now) and covered in tiny hairline cracks as if the sun has damaged it.

greys better outside white breaks down with the weather.
if you push it you'll probably find it will just break.
so you more likely end up replacing for new.
