How to find a sprinkler leak

Start at the water meter: read it before and after two hours with no water running. If it moved, you probably have a leak.

Check this first

  1. Do the meter test: check the meter before and after a two-hour period with no water use (EPA WaterSense).
  2. Inspect the system each spring for frost or freeze damage before the first run. The EPA says a leak 1/32 inch across can waste about 6,300 gallons a month (EPA WaterSense).
  3. Lowest head dribbling after a cycle? If it stops once the pipe drains, it’s low head drainage, not a valve leak (Hunter).
  4. Monitor flow. The EPA notes leak-detection and flow-monitoring devices can alert you to leaks and unusual use (EPA WaterSense).
