Hello everyone,
we have received our detailed construction plans. The issue concerns the drainage of our kitchen. Underneath the kitchen is our basement living area made of waterproof concrete. Now, the drainage from the island with the sink is planned to be routed downwards into the basement room below (which is a living space because it’s a basement living area) and then further to an exterior wall, from where the pipe will be brought down from the ceiling. I hope I explained it clearly?!
I find it quite unattractive to spoil the nice living space like this, since a 10cm (4 inch) pipe will run across the room, and then the pipe will also go down along the wall from the ceiling and will need to be boxed in.
Is there no more elegant solution, or does my builder just want to choose the cheapest option for themselves? My layperson’s opinion would be to place the drain pipe inside the ground floor ceiling and run it along a room edge before going down. From what I understand, I can’t avoid the boxing-in in the basement due to the waterproof concrete?
Thank you in advance for your help.

So, I checked again. It will be a 70mm (2.8 inches) pipe. At the moment, it is planned to run under the ceiling of the basement room (living space). Since the pipe needs a slope, it will probably require a 10cm (4 inches) boxed-in section. The pipe would then be in the middle of the room, about 2m (6.5 feet) away from the wall.
I asked if it could be installed within the screed, but I was told that if there is ever any damage to the pipe, the entire ceiling and screed would have to be broken up.
I’m not happy with the boxed-in section. I could also lower the entire ceiling, but then I would lose 10cm (4 inches) throughout the whole room. Fortunately, the room height is 2.50m (8.2 feet), but I didn’t increase the ceiling height only to lose it again by lowering it.

By the way, a 70mm (2.8 inches) pipe does not equate to a 10cm (4 inches) duct. The duct requires space, as does the pipe support, which usually needs 10-20mm (0.4-0.8 inches). Plus, you still need fittings, such as the bend from vertical to horizontal.

So, in our case, a few meters of water and wastewater pipes are also installed under the screed, which I don’t see as a problem. If there is ever damage, it would of course be a real hassle, but the likelihood is quite low, and it’s not about 10m (33 feet). They are probably more concerned that the slope might not be set correctly, and then they would have to break everything open again themselves *g*.
A standard sink is supposed to drain through this. No idea why a 70mm (2.75 inches) pipe is used. I can only pass on what I was told.
- So, what would be the slope for a 70mm (2.75 inches) pipe?
- Would a HT 40/50 (1.5/2 inches) pipe be sufficient for a sink?
- Is an alternative installation in the ceiling/screed possible or not?
Are there any alternatives I can suggest to the builder?

Ours is a 50mm (2 inch) pipe, the same size used for bathroom sinks. As far as I know, a smaller pipe means a higher flow velocity, which you actually want (keyword "fat").
