18. Install valve Boxes and BaCKfIll tRenCHes
Once you have verified there are no leaks install all the valve boxes for the system and backfill the
trenches.
When backfilling trenches make an effort to ensure there are no large rocks resting on or against the pipes
and fittings. As your soil settles with time large rocks can cause premature failure.
Be careful not to cut or damage the sprinkler wires when backfilling. It is very difficult to find and repair bad
wiring after the system is buried.
