Sprinkler Coverage Problems: Why Part of the Lawn Stays Dry

A dry patch does not always mean the entire zone needs more watering time. Often the problem is distribution: water is reaching some parts of the zone but not the area that needs it.

Check for blocked or tilted heads

Grass, shrubs, edging, and landscape growth can interfere with a spray pattern that worked correctly when the system was installed.

Look at head-to-head coverage

Sprinklers are generally intended to overlap. If one head is damaged, capped, moved, or fitted with the wrong nozzle, a gap can appear between neighboring patterns.

Pressure problems affect distance

Low pressure can shorten throw distance across several heads. A leak or valve restriction may therefore look like a coverage problem.

Fix distribution before increasing runtime

Running the zone longer can overwater areas that already receive enough water while the dry spot remains under-watered.
