Avoid These 7 Common Irrigation System Problems After Summer Storms
Andrew Davis
Florida summer storms are notorious for wreaking havoc on irrigation systems. After heavy rain or strong winds, check your system for problems that can lead to overwatering, under-watering, or system failure. These are 7 of the most common post-storm irrigation issues — and how to fix them.
1. Broken or Clogged Sprinkler Heads
Storm debris can knock sprinkler heads out of position or clog them entirely. Look for heads that no longer pop up, spray in unusual directions, or have stopped working. Clean clogged nozzles gently using compressed air, a soft brush, or a cloth.
2. Leaking Pipes or Fittings
Saturated soil can cause pipes to shift or joints to loosen. Check for puddles, bubbling water, or unusually wet spots around sprinkler heads — these are signs of a potential underground leak.
3. Incorrect Head Height
Storms can cause sprinkler heads to sink too low or rise too high. Uneven height can result in poor water distribution or make heads more vulnerable to mower and trimmer damage.
4. Water Pressure Problems
Shifting lines or debris may affect water pressure:
Low pressure can reduce spray distance and cause uneven coverage.
High pressure may lead to misting, which wastes water and damages parts.
Check system pressure and consider adding a pressure regulator if needed.
5. Controller or Valve Malfunctions
Electrical surges or water intrusion may disrupt the irrigation controller. After a storm:
Make sure the controller is turning zones on and off properly.
Check that valves aren’t stuck open or leaking.
Ensure the system isn’t running multiple zones at the same time.
6. Rain Sensor Failure
Your rain sensor prevents unnecessary watering after storms. Confirm it’s still mounted correctly, dry, and responsive. If the system runs after heavy rain, the sensor may need to be replaced.
7. Uneven Coverage or Scheduling Issues
Storm damage can disrupt spray patterns or displace sprinkler heads. Look for:
Mismatched sprinkler heads in the same zone
Heads that were moved or misaligned
Poor water distribution across zones
If your soil is already saturated, reset your watering schedule or pause the system temporarily to prevent overwatering.
