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.
