Soil Stack Connection Problem

[m4rcus]

Hi,

I'd like to pup a new connection into the soil stack, see attached photo to show the location circled in red. The diameter of that boss is ~44mm yet I want to connect a 40mm solvent pipe to it (43mm OD). I've been looking for boss adaptors, but these would all be the wrong sizes, can I just solvent weld into it (after cutting a hole!)

Yes go for it.

Thanks Pete, can you be a little more convincing?

What is the make of the 4" tee you want to cut into ?

Looks like Osma/Wavin.

But could be wrong. I avoid poop chutes as much as possible

Yes go for it big style my son. Offer up the 40mm solvent weld pipe to it and it should be a snug fit, if so core it out and weld it in.

That's more like it Pete.

So is a straight weld they way it's meant to me done? I see the current style ones all seem to have an adaptor boss first, but the ID of the boss is much bigger...

You can get all diff sizes with diff manufacturers, floplast, Hunter, wavin the list goes on. Generally you only use an insert on a strap on boss so if the sleeve on your soil pipe is a good fit with a 40mm pipe or even a coupling if it is loose go for it.

If you need any more encouragement I will send up the cheer leaders
