Yes, a residential landscape sprinkler system requires regular maintenance. This includes checking for any broken or clogged pipes, adjusting the water pressure and flow rate to ensure optimal coverage of the lawn area, and ensuring that all heads are properly aligned and positioned correctly, so they don’t spray onto walkways or other places not intended for watering, replacing worn out parts such as nozzles and filters regularly to maintain efficiency, inspecting valves for proper operation and making sure backflow prevention devices are in place. Periodic inspections of the timer settings should be conducted to ensure they are appropriately adjusted according to local weather conditions.
