soil stack adaptor query

[Ian McGuire]

Hi Oracles of all things plumbing,

I have to replace a cast iron soil stack which is simple enough, done a few up here in Scotland, however, client wants to retain the 3" toilet waste as he does not want an enlarged hole making in a newly rendered wall, which 110 to 75mm fitting is best? trying to find something online but not sure of the quality or viability of the material on some of them, look like cheap 3d prints.

What do you use/recommend?

cheers for help

Mac

Probably something like that. I expect you'll struggle finding one that will match the same brand soil stack you use though and you will need to or the colours will be different
