Fall Irrigation Maintenance Guide
As temperatures begin cooling across Georgia and South Carolina, your irrigation system's watering needs change significantly. Fall is one of the most important times of year for sprinkler maintenance because it prepares your system for winter while helping your lawn recover from the stress of summer.
Whether you live in Augusta, North Augusta, Aiken, Beech Island, or Graniteville, a fall irrigation inspection can extend the life of your system and prevent expensive repairs next spring.
Reduce Your Watering Schedule
Cooler temperatures mean your lawn requires less water.
If your controller is still running on summer settings, you're likely overwatering.
Reduce:
Run times
Weekly watering frequency
Seasonal percentage settings
Smart irrigation controllers make these adjustments automatically.
Inspect Every Zone
Run each irrigation zone and look for:
Broken sprinkler heads
Clogged nozzles
Leaks
Poor coverage
Tilted heads
Low pressure
Repairing these problems now prevents them from worsening over the winter.
Trim Landscape Around Sprinklers
Shrubs, flowers, and ornamental grasses often grow significantly during summer.
Trim vegetation blocking sprinkler spray patterns to restore even water distribution.
Inspect Valves and Wiring
Check for:
Valve leaks
Damaged wiring
Corrosion
Loose electrical connections
Addressing electrical issues before winter reduces the likelihood of spring startup problems.
Clean Filters and Nozzles
Sediment buildup can reduce system efficiency.
Cleaning nozzles improves spray patterns and helps every zone apply water more evenly.
Consider a Controller Upgrade
If your controller is over 10 years old, fall is an excellent time to upgrade to a Rain Bird smart controller before the next growing season.
Schedule Preventive Maintenance
A professional fall inspection helps:
Catch hidden leaks
Improve efficiency
Extend equipment life
Reduce repair costs
Prepare your system for winter
How Often Should You Inspect Your Sprinkler System?
Your sprinkler system should receive a complete inspection at least once each year, but twice annually—once in the spring and once in the fall—is ideal for most homeowners.
You should also perform quick visual checks every month during the irrigation season. Walk your yard while each zone is running and look for broken heads, clogged nozzles, leaks, low pressure, or areas receiving too much or too little water. Catching these issues early helps prevent higher water bills and costly underground repairs.
If you notice sudden increases in your water bill, soggy areas in the lawn, dry patches, or sprinklers that won't pop up or retract, schedule an inspection immediately rather than waiting for your next routine service.
