The Leak Defense System is a whole house water leak detection system and automatic water shut off valve. It uses a flow-sensor and a motorized ball valve to constantly monitor water flow into the house. This system uses "Home" and "Away" modes for adjustable time and volume intervals for your custom water use habits. While the timers can be adjusted at the backlit touch-screen control panel according to personal preference, the flow settings for this system should be calibrated to each home individually after installation. This valve system is available from 3/4" up to 2" for larger homes or commercial applications.

Most items needed for the System are included:

  1. Backlit touch-screen control panel with 10' cable lead (extra cable may be ordered up to 200')
