Not all flow sensors
are created equal
A detection system is not a guarantee that you won’t have a leak, but this kind of durability, sensitivity, and quality technical support when you need it means that if a leak happens you can count on the device to detect it, take action, and never be in the dark again.
The Leak Defense System®
Our proprietary electronic flow sensing technology is second to none for performance and reliability in water conservation and leak protection.
