I had insisted that all pipes installed including under decking for drainage be schedule 40. Well they used sewer pipe instead but have not put down the rebar yet. Can still be changed out but would have to redo everything- the gutter drains and the slotted drains have been installed today. My issue is that if these drainage pipes are ever collapsed or broken by some unforeseen future excavation or construction, flooding could occur.

Looking for opinions if I should have it changed out to schedule 40 pipe or leave as is.

Is it SDR?
An article that I read said that the SDR is actually better in sewer/drain applications since it is not under pressure the thinner walls allow it to flex more readily than schedule 40.

A little counter intuitive, but that's what it said.

Does the pipe stamping say DS2729 or SDR35? If SDR35 don't worry, that's the sewer & drain equivalent of sch40 for pressure pipe.

What craig said.

SDR35 is da best. Only thing we use for surface drainage applications besides concrete.

S&D is weak ass **** and yes if that is what it is make them pull it and put SDR. SDR is usually green or blue but we have gotten it in white before and made them swap it out just on principal

Biggest thing you need to make sure of is there is positive grade away from house and away from pool into what I'm assuming is a channel drain. Also, even if it's extra cost on you, I would make them put in the 6" wide duraslope channel drain. It obviously has a larger intake area and the flow line is set with slope so it never holds water. Just make sure they install it with the flow arrow going the correct direction.

Thank you all for the replies. Trying to decide if this needs to be redone or just live with it.

So the 4" drain pipes are green and have " sewer pipe astm d2729 3000# crush" on them. Above is a 4" pvc C channel drain which is sturdy looking.

Is this pipe acceptable?

The pool coping is about 8 feet away from our master bedroom and they put one c drain level with my slab on the home just below the bottom brick, so the slope is TOWARDS my house. Plan on getting this changed for sure. Issue is that pool coping is only 8 feet from the house slab. With the coping being slightly higher than the slab.

That seems like a disaster waiting to happen

It is also sloped towards the main drainage contour side of our house and at the end run of the concrete decking. We did move the channel drain away from the house. 10,000 sq ft lot but with the utilities under the back part of our lot, we were tight putting in an 18x36 with spa. Hopefully all will end well.
Thanks again for the replies.
