Seal for a soil pipe

[SollyJ]

Hi

I have a cast iron soil pipe which has a small leak from the access panel.

I imagine there is a gasket / seal that has perished and needs replacing, but I have no idea where I can get one from.

We live in Muswell Hill (London N10).

Any advise will be received very gratefully !!!

Thanks
Solly

you will have to cut a new one from some sheet rubber or use a sealant on top of the original
