Irrigation Maintenance and Tune Up Check List:
Look For Leaks
- Turn off all water and read your water meter. On the water meter face is a red triangle. If this moving
clockwise you may have a water leak.
- If you are on a well, have an irrigation professional check your system.
- Make sure the clock is set for the proper day of the week and time of day is correct.
- Make a list of all the stations and where they water. Include type of plant being watered and type of
heads. Place list in the controller for future reference.
- In the controller has battery backup, replace it at the beginning of each watering season.
- Repair or replace broken or missing rotor heads, spray heads, "Bubblers", and drip emmitors.
- Make sure all heads pop-up all of the way and fully retract when the water is turned off.
- Check for sprinklers blocked by grass, plants or other obstacles. If the spray is blocked, remove the
obstacle or move the sprinkler head.
- Make sure sprinklers are vertical and flush with soil grade. Soil should be tightly compacted around the
- Check for proper pressure. Water will stream out of the sprinkler instead of forming a spray if the
pressure is too low or mist excessively if it is too high.
- Clean or replace clogged nozzles and clean the sprinkler's trash screen if it has one.
- Make sure all heads direct water to landscape and not to impervious surfaces such as concrete.
- Water at night, preferably between midnight but no later than 7 AM.
- Determine the maximum run time for each zone before run off starts. This often occurs after about 5-10
minutes for clay soils or after 18 minutes for loamy sand soils. Decrease these times for slopes. If
runoff is a problem, irrigate more often for shorter periods, waiting at least an hour between watering.
- Make sure a rain sensor is properly installed, set at one-fourth of an inch or less and not sheltered by
walls, shrubs or other plants.
Always FLAG Sprinklers Before You Aerate!!
