Sprinkler Pipes in Ground
This should give you a pretty good idea what the sprinkler
system looks like underground. Some sprinklers are buried in the ground
over 12 inches deep but most sprinklers are around six to 8 inches.
You should use caution when digging for trees are plants to avoid
damaging the shallow sprinkler piping.
You will be able to inspect the sprinkler system by turning it on and
off to get a visual idea of what is getting covered with water properly.
