Protecting underground PVC

[JohnT]

The first 90 is probably the most common leak point. It's just movement and leverage that does it in. I doubt anything short of a tree would cause problems.

Thanks John! With that in mind, I won't worry about protecting it. (Makes things easier anyway) :^)

Thanks!

It is a typical design for a civil site plan to pour some concrete around those elbows to absorb the inertia of the water hitting the turn. If you -really- want to protect -all- the PVC, you can encase all of it in concrete. That's usually only used on PVC that carries electrical or data cabling. So the guy on the backhoe installing a sprinkler system 20 years later doesn't dig through it.
