Help! Sealing a waste pipe

[Matt Farrington Smith]

Apologies for the basic question but what would I use to seal the following [attached]?

We've had drips coming from our bath for the last few weeks and haven't been able to identify the source. Last night I struck pay-dirt.

Cheers,
Matt

TBH wants removing and reinstalling with some mastic

As above, remove it, clean all old gunk off and silicone it back in

Thank you chaps! Is it easy to get that piece out?

 

[ShaunCorbs]

Looks like it unscrews from the top

Most of the time they are.

The top will probably be screwed through to the bottom but there will probably be a lot of sealant between the top and the bath and between the bottom and the bath. In theory they should seal with the rubber gaskets but they nearly always need sealant as well. You might need a bit of patience and a Stanley knife to get it off.

Looks likes it's been "fixed" before, might be worth replacing entirely if the rubber gasket has perished.

I would put a new one in also. Forgot to put that as part of my first post.

You're right a new trap only costs a couple of quid.
