Questions and Answers for Advanced Drainage Systems 3 in. x 10 ft. Singlewall Solid Drain Pipe

A:  100% it can be walked over. No doubts. I used it in a massive permeable paver/french drain project years ago. I installed it under the pavers in a rock bed so water can drain under the pavers in to the pipe.

A:  Yes, if using the slotted pipe. No if using the solid (not-slotted) pipe.

A:  Yes, if you have holes in your pipe

A:  No. This is a solid pipe. The perforated style you would need to to keep debris for clogging the holes for drainage. This is also only to transfer water. If your looking for a leach style run you’ll need the latter. Solid near foundations and perforated where the water will start to leach back into the soil.

A:  3-1/2 inches

A:  The outsider diameter is 3.5 inches. I think the 3" spec. refers to the size pipe it mates to.

A:  I think the lower limit of the bend radius is about one foot. It might be a little smaller but that's a good rule of thumb. If you want tighter then get a 90 degree coupler.

A:  It's plenty flexible enough to do the job.

A:  Could get 180 bend around about a 2-1/2/3ft arch

A:  Diameter.

A:  Diameter, and if I recall correctly, that's inside diameter.

A:  Yes, with either an inside coupler or an outside coupler. Or you can cut a two inch slit on one end, squeeze it together and push it into the other pipe.

A:  Yes , and the 3 IN Tube is available in the store so you can even go and try yourself, the 4 IN is available on line (Homedepo.com) and for both you can connect 2 pipes or more together.

A:  Yes.one female end and one male. You’ll need pipe tape or I used roofing sealer in a tube and gun to glue them together unless Weeping joints don’t matter then whatever.

A:  No fun digging ditches but installing drain pipe, filter sock easy as pie

A:  Yes, but I don't know which particular fittings will work. Take your corex drain pipe and your PVC into Home Depot and experiment with all the different corrugated pipe and PVC fittings and reducers. That's what I did. Once you find what you need and attach your two pipe, you might want to screw in one small stainless steel screw at the connection as well.

A:  Not the ideal solution, but I think it would somewhat work.

A:  Push the male end into the female end.

A:  @Roberto Thanks for answer my question. Should I push male end pass the 4 Knots on female side or should I stop the male end there? If I stop male before 4 knots it is very loose and easy for 2 pipes to separate. But no matter how hard I push, the male end cannot pass the 4 knots. I tried to screw male end to pass female’s 4 knots, but I failed. Do I need special coupler/connector?

A:  I would use caution and bury it as deep as possible for maximum support of the surrounding soil. Also make sure that it is well packed.

A:  I've worked with this material quite a bit. My first thought is that it would not support an auto driving directly over it. But if the pipe is laid in a trough and the weight can be distributed a bit into the trough and rocks, then it might. The white schedule-40 PVC pipe might be stronger. I'd run a test first.
