Kitchen island (piping installation) (Ed.)

[Tporter23]

Hi all wondering if anyone could give me any pointers

I’ve been asked to first fix some pipework to a kitchen island . Trouble is it’s half wooden floor and half concrete. Im hoping I can get the correct fall to outside.

I’m using solvent weld 40mm waste and plastic hot and cold hep20.

Any recommendations in regards to protecting the pipework? Shall I insulate it? Whats best to fill the chase with ?

First time doing a job like this so any advice is appreciated, it is my first year been self employed and as much as I’m mcloving it (sometimes) i find it hard to ask for advice out here on my own

Thanks all

If the waste is any sort of length I'd go up to 50mm .
Are you just cutting up screed or a decent chase through concrete section?

Thanks for the reply my plan was to sleeve the 40mm in 50mm and the 2 hot and cold supplies in some 32mm or something. Just a decent chase through concrete about 1.5m . Got plenty of room on the external wall to core through and still have a good drop to the gulley
