Sprinkler System & Irrigation Leak Diagnosis

Direct Service Resource: Need immediate professional assistance for this issue? Visit our dedicated Yard Irrigation Line Diagnostics page.

In the arid climate of Rialto, CA, residential lawn irrigation systems run automated schedules several times a week. Because sprinkler lines operate at full line pressure up to the solenoid valves, underground PVC fissures can waste thousands of gallons undetected.

Common Irrigation Leak Symptoms

  • Low Sprinkler Head Pressure: Spray heads barely popping up or spitting air bubbles.
  • Sunken Lawn Depressions: Wet mushy turf surrounding valve boxes.
  • Constant Weeping at Backflow Preventer: Water continuously trickling from the copper Reduced Pressure Principle (RP) backflow device.

Our acoustic geophones isolate cracked PVC manifolds without destroying your lawn.
