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

🔍 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.

🧪 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.

💧 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
