How To Detect An Underground Irrigation Leak
Underground irrigation leaks often go unnoticed until they cause high water bills, soggy lawn areas, reduced sprinkler pressure, or dying grass. Learning how to identify the warning signs early can prevent costly landscape damage and unnecessary water waste.
Why Underground Leaks Are Serious
Regular sprinkler inspections help prevent expensive irrigation repairs, reduce water waste, improve lawn health, and ensure every zone operates correctly. Small issues such as clogged nozzles or leaking valves can quickly become larger problems if ignored.
Step-By-Step Leak Detection
- Spring: Full system startup inspection.
- Summer: Check coverage and water pressure monthly.
- Fall: Inspect heads, valves, and controller before cooler weather.
- Winter: Inspect exposed components and prepare for freezing temperatures when necessary.
DIY Leak Detection Tips
- Look for broken or tilted sprinkler heads.
- Check for soggy spots and hidden leaks.
- Verify each irrigation zone operates correctly.
- Test the controller schedule.
- Adjust spray patterns to avoid sidewalks and driveways.
