Cast iron soil pipe adapter
I am fitting a toilet and have to join into the old cast T piece. I cut the old pipe out and the lead but now have a connection of Id 125mm. I want to
connect 110mm plastic into it but all the adapters seem to have rubber fins at 115mm. Does anyone known of a product the right size?

If fitting into the T you will need a "collar" of the old cast iron in there first. Well, that is how I did it.

Yeah I just starting to think that. I have a short straight length that went thru the wall. I'm thinking cut a ring off that and bond it in with
sealant then adapter for the plastic. I can't find an.adapter that goes straight in. What did you use to fix the collar in.

you get a rubber coupling that adapts iron to plastic, plumbers at work call them timesaver couplings, not sure if thats a trade name or generic name
for them. you may have to cut above and below and add a plastic tee.
most builders merchants plumb centre etc will have them

It's 4" but I removed it from the T and all the lead that held it in. The socket I'd 125mm I'd. I wish I'd cut the pipe
flush now, then I could use the adapter they have in wickes and elsewhere.

I cut the pipe and left a few inches in the T!
A bit of silicone or whatever should hold it in place though.
