When a catastrophic leak alert occurs, flow has exceeded the catastrophic leak and evaluation time thresholds during non-irrigation hours.

Possible Causes

• Someone is using a quick coupler or hose bib.
  
  
• A valve is not closing completely and is leaking.
  
  
• A mainline fitting has a crack and is leaking.
  
  
• A quick coupler is stuck partially open or a hose bib has been left open.

Possible Fixes

• Repair any valves, quick couplers or hose bibs.
  
  
• Prevent the unauthorized use of a quick coupler or hose bib.
