Drain pipes - in concrete or in ground underneath

[Petermet]

My pool is being built in Indonesia - which has very different construction processes.

I have 2 linked floor drains. They make the pool levels with a thin layer of concrete and then pour reinforced concrete to 6 inches.
My pipes are 2 inches.

Is it ok for the pipes to be on top of the leveling concrete and within the 6 inches of reinforced concrete or should be be below the leveling concrete in the ground and backfilled with sand?

To make sure we understand each other, it should be something like this:

1. Pool shape dug and formed in ground
2. Plumbing PVC placed
3. Rebar support and preparade before gunite/concrete
4. Gunite/concrete installed
5. Final surface (plaster coloring, pebble, etc) installed.

See this thread as an example.

New 32'x20' Gunite Pool in South Alabama - Build Thread

Back in October the wife and I pulled the trigger on a 32'x20' Gunite pool here in Fairhope, AL on the Gulf Coast. We've been in the house for 10 years and it used to have a 14'x22' wooden deck off the back porch. Even though the deck was treated wood, it rotted/deteriorated badly so we...

I don’t think you want pipes embedded within the 6” reinforced concrete, except to penetrate tmatraight through it for returns or suction. It’s difficult to understand what you mean with the leveling concrete but I think I’d run the pipes under that. But I’m also not in Indonesia so maybe they have some other considerations in play. Kinda curious to see what that process looks like.

They propose drain pipes like this. So 2" at the bottom of the concrete and 4" above - is this ok for drain pipes?

Hopefully some Teflon tape will seal it. Be careful not to overnighten it as with fresh tape it will go on easy. Go hand tight and see if it still leaks. Then 1/8 turn if need be with a wrench. Temperature changes/drops can alter the PSI a good deal, so hopefully what you are seeing...
