Kitchen sink waste

[nicholas221078]

Hi All.
I'm moving my sink to a centre island that I'm installing next week.

The island is up against the outside wall.


I'll be drilling a hole for 40mm pipe under my dpc , is it best to just Mortar the pipe in after I'll make sure I don't damage the membrane etc.
(I can't run above due to the back door ill be running the pipe under )

I'll be running the 40mm solvent pipe under my floor joists, I'll be putting a standard trap on my sink , is there a solvent to push fit adapter on the market, I'll use push fit pipe out of the trap but then need something to convert.

Thanks

Push fit will work with solvent pipe.

You can use a compression fitting to join push fit pipe to solvent weld pipe.

Push fit will work with solvent pipe.

No it wont, the OD of the pipe is a different size. Only way to join the 2 is using a compression joint.

Curious though as to why your doing so much with solvent weld stuff then want to swap to Push Fit, it'll be more professional to do the lot in solvent weld.
