How It Works


Leak Defense System Valve

The Leak Defense System automatic water shut-off control valve is installed on the structure’s incoming waterline. Once installed, it monitors water flow 24/7. There’s a pipe size to fit every application from ¾" to 3". It’s the best water leak detector on the market for leak protection!

White Control Panel for LDS

Control Panel

Water usage varies in every application. The user-friendly wireless control panel lets you set your Leak Defense System to fit the water usage needs of your family’s lifestyle, business or building needs. It can also be connected to a 3rd party monitoring company to make sure an alert always gets attention even if you’re not around.


Your Mobile Devices

Going on vacation? Have a vacation home and want to make sure all the plumbing is water tight? Simply register your device and enjoy remote control of your Leak Defense System. If you travel frequently or have multiple systems, you can monitor and control each system individually. This feature is especially valuable for someone who owns multiple residential properties.
