PVC vs Poly pipe around big trees

[leak_chaser]

Which will stand up better to big tree roots?

Thanks.

Actually, maybe neither, because the biggest problem is usually the roots growing around the pipe and "choking" it. ANY plastic pipe can be squeezed closed by roots.

Big trees and plumbing generally tend to not get along.

PVC piping has less give than Poly so will tend to crack slightly sooner.

If you really want to run a house supply past shallow tree roots, you would start at sch 40 PVC and work up from there. Poly pipe is not to be considered.

To be really really conservative about it, you could even go with galvanized steel serving as a pull sleeve to encase plastic tubing.

We sleeve poly all the time up here through 4" sch 40 PVC when we have a real rocky trench and under driveways. The stuff is damn near indestructible. Lay your 4" in the trench, glue it together, tape a golf ball to the nose of the poly & shove it in.

All done.

Maybe, usually, but I had a friend who had a sewer of it and the trees squeezed the pipe closed.

Really? A picture of that would make quite the conversation piece
