Toilet output pipe

[Inchiquin]

I'm replacing my toilet. The lead output pipe has a flanged opening - see photo. The flange is too big for a standard pan connector while the main body of the pipe is too small. Also the flange is not very deep, about 25mm. I may replace the pipe at some point but it will be a big job (2ft thick millstone grit wall and will probably need a core drill to widen the existing hole a little) so I don't want to even consider it until the weather gets warmer. So in the meantime I'm wondering if I could just pack lots of sealant around the pan connector, and maybe wrap some sort of waterproof lagging round the outside of the joint. Does this sound reasonable, and what could I use for the lagging?

Many thanks for suggestions.

The pipe itself must be lead because it has a bend in it outside the wall, but I did wonder if the flange was cast iron. Unfortunately I've put the old toilet back for the moment so I can't check it.

As for the McAlpine socket you mentioned, it says it has a finned connector to a 110mm pipe, but isn't that exactly what a standard pan connector has? And as I said, that's too small for the flange and too big for the pipe.

Spray it with silicone sealant and you will be surprised what can be squeezed in.

Try a magnet on it, it will stick to cast-iron, but not to lead.

Could be 3½" instead of a 4" pipe which was common for WC final pipework. Most manufacturers make the smaller size. You can also get 3" connectors.

Yup +1, measure the smaller pipe - 31/2" cast was common and there are plenty of adapters (McAlpine/Multikwik/etc)

It's lead with a brass "thimble" on the end. AS denso says .... look at multiquick connectors ( and others)

Many thanks for the replies. The pipe does indeed appear to be 3.5". I wasn't aware of that size - I had it in my head that old lead pipes were 4". I need a short extension from the pan to the outlet and I was originally planning to use a rigid extender cut to the required length. I'm thinking now about using a McAlpine flexible connector with 3.5" outlet.
