To determine whether a water leak is coming from an irrigation line or the main water line, you can follow these steps:

πŸ” 1. Check the Leak Location

  • Irrigation leaks are often found near sprinklers, valves, or drip lines, usually in landscaped areas.
  • Main water line leaks typically appear between your water meter and your house, often in the front yard or under pavement.

πŸ§ͺ 2. Shut Off the Irrigation System

  • Turn off the irrigation timer/controller and any manual valves leading to the irrigation system.
  • Wait 15–30 minutes.
  • If the leak slows or stops, it’s likely coming from the irrigation system.

πŸ’§ 3. Use the Water Meter to Diagnose

  1. Turn off all water in the house (faucets, appliances, etc.).
  2. Check the water meter:
    • If the dial is still spinning, you have a leak.
    • Now, shut off the irrigation valve (usually found near the backflow preventer or main irrigation manifold).
    • If the dial stops spinning, the leak is in the irrigation system.
    • If the dial continues, the leak is likely in the main line or house plumbing.

🧰 4. Inspect Irrigation Components

  • Look for soggy ground, pooling water, or unusually green patches near:
    • Sprinkler heads
    • Drip tubing
    • Irrigation valve boxes
