Water pipes running through extension floor

[stuey44]

Hi.

I've been picking up some excellent help on this site but now find I need to ask a question.

I'm putting a single storey rear extension, moving the kitchen wall out, resulting in my sink moving to the new back wall. I will need to move the meter/pipework under the current sink to the new location going through the new floor.

At what level should this pipework run to get to it's new location? Through the hardcore? Through the screed?

Really appreciate some guidance. Concrete poured, base up next!

Depends on over site make up.
Is your insulation underneath concrete
Or is insulation on top of concrete with 65mm screed.

Above any insulation, and above any structural slab, and preferably in an accessible duct in the screed layer rather than just covered in screed
