Replace broken or missing sprinkler heads.

Make sure the spray heads turn properly.

Adjust heads so that water does not reach streets and driveways.

Check nozzles for plugging.

Renozzle/spray heads with MP Rotators.

Place straight-sided containers (such as tuna fish cans) around the yard during irrigation and measure water depth so that you know how long it takes to apply ¼ to ½ inch of water.

Place containers on persistent dry spots to determine if poor sprinkler coverage is the problem.

Never water if the soil is still wet.
