Marley sa42 or some other soil to 110mm adaptor?

Hi All,

I have a situation where I have an old mortar based clay soil pipe going down into the ground from an old soil stack that I need to cut the collar off and put in a soil adaptor. I am guessing the adaptor will only protrude a few mm once fitted as I require to keep to the lowest possible height to still get a 90 bend under the floor to reuse this for a downstairs toilet.

Also as this won't be accessible once fitted is this OK for building regs?

Thanks in advance!

Ignore my size issue as I can see it would work regardless, however I wonder in a concealed non access space will these adapters pass bc?

Thanks

Don't see as its any different to a pan connector on a wall hung pan, with concealed pipework. If the joints are done properly, it shouldn't ever leak.
