Patented Technology.

Not all flow sensors are created equal. A detection system is not a guarantee that you won’t have leak, but this kind of durability, sensitivity, and quality technical support when you need it mean that if a leak happens you can count on the device to detect it, take action, and never be in the dark again. With no moving parts and a full-port flowbody, we can offer you pinhole leak detection and no drop in your water pressure.

We can do it all.

We have a variety of accessories that have been developed to make the transition to a leak free life as fluid as possible. From outdoor timers to an Alarm Panel Interface that lets you automatically put your system in the Away mode when you arm your security system.

Leak Defense System available in 7 sizes from 0.75″ to 3″.

Made with full-port, Italian-made Bonomi valves and actuators. Developed and assembled in San Diego, CA.
