About this product

Stop leaks automatically—no power, no hassle

Protect Your Home and Water System with Automatic Leak Detection

The Vertex Auto Shut-Off Valve is a mechanical leak detection and automatic water shut-off system designed for residential and light commercial point-of-use water treatment appliances. It automatically halts the water supply upon detecting a leak, preventing potential water damage.

Key Features & Benefits

  • Automatic Leak Detection: Shuts off water supply when a leak is detected, safeguarding against water damage.

  • Mechanical Operation: Functions without electricity, ensuring reliability even during power outages.

  • Easy Installation: Quick-connect fittings for 1/4″ or 3/8″ tubing; install using pre-molded mounting holes or adhesive strips.

  • Reusable Design: Activation cartridge can be easily replaced without tools or disassembly.

  • Versatile Application: Ideal for under-sink RO systems, water dispensers, and other point-of-use water appliances.

 

Best for
  • Under-sink reverse osmosis (RO) systems with 1/4″ or 3/8″ tubing.
  • Bottleless water coolers, water dispensers, or other point-of-use water filtration appliances.
  • Light commercial and residential installations where reliable, power-free leak protection is required.
  • Facilities, offices, or homes where unattended water-using appliances pose a risk (e.g. during weekends or vacations).
