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.
