Impact Sprinklers — The Impact for Your Lawn with Sprinkler Master Repair (Utah County)

An impact sprinkler uses a moving arm to interrupt the water stream and rotate the head. If it stalls, spins unevenly, or leaves dry areas, check the model and operating conditions before replacing it.

Check the simple causes first

Look for a blocked nozzle, dirt around the mechanism, an incorrect arc setting, or pressure outside the model’s operating range. A leak or too much flow demand elsewhere on the zone can also affect performance. Do not assume a smaller nozzle or an extra head will solve the problem.

Follow the manufacturer’s cleaning instructions. Rain Bird’s troubleshooting guide explains that its impact sprinklers are water-lubricated and should not be oiled. Use the guide appropriate to your model.

Check coverage after a repair

Run the zone and watch the full pattern. Keep water off paving and check the areas between heads. If one part of the lawn stays dry, increasing the entire zone’s run time may overwater other areas. Our dry-spot troubleshooting article covers other possible causes.
