This is a follow up to a previous problem I had here: PVC Pipe for sprinkler system broken in multiple places
Does anyone have any suggestions how I can install underground PVC pipe and protect it from Tree roots.
A few suggestions I've thought of are these.
-
Inserting a 3/4-inch PVC pipe inside of a 2 inch PVC pipe for short distance (10-20 feet). if a tree trunk or root pushes into the pipe and breaks the 2 inch PVC, that should give the 3/4 inch pipe that's inside some protection.
-
Placing small rocks under, and on the sides, and finally above the pipe. To give it another layer of protection.
Anyone have any other suggestions or think my 2 solutions are bad ones? I'm open ears.

PVC pipe is the most common pipe used for sprinklers, but in areas that require a lot of bends, there is also something known as "funny pipe".
Funny pipe example
This flexible pipe is not the same as drip irrigation pipe. It is thicker and a slightly different material. Some brands are UV resistant and it can be used above ground in flower beds or in shallow areas where it may get uncovered.
Tree roots may still kink this pipe over time, but the should not break it because it will just bend and flex out of the way.
