Spring is a great time to tackle irrigation system maintenance. Irrigation problems are not always apparent during the cooler times of year, but once summer heat arrives, your system will be providing a lifeline to your plants. Here’s a checklist for some routine maintenance:
- Inspect all components of your watering system, from the backflow preventer to the valves, for standing water, soggy ground, or eroded soil. If you have a controller, check that the programs are correct. If the controller has battery backup power, replace the battery at least yearly.
- Sprinklers should be checked frequently since they are above ground and can easily get damaged or misdirected. Check the irrigation line from the valve to the spray heads for leaks. Replace spray heads if necessary, and be sure to replace with the proper spray head. Check that sprinkler heads are flush with the soil surface and straight, not tilted. Clear grass, plants and other obstructions that block sprinkler spray. Finally, adjust sprinkler heads so they don’t spray walls, driveways, or sidewalks.
- For drip irrigation, turn on the system 20-30 minutes before the inspection to allow enough time for emitter wetting patterns to show. Check from the valve to the end of the irrigation line for leaks or clogged emitters. Check for proper emitter placement on plants as they grow. You may need to move emitters out to the drip line of the plant each season. Do this by purchasing some extra micro tubing and connectors.
