Add Z-Wave magic to your existing plumbing.


Amazon Walmart Home Depot
Smartest Home Home Depot Nexia Logo

A burst pipe or leaky toilet can seriously mess up your life. Turn off your water automatically when leaks are detected or when you travel out of town. It can even automate your water heater or anything else indoors that uses a quarter-turn ball valve (without a plumber or cutting into pipes.)

Shutoff Valve USAGE IDEAS



Automatically shut off the water main when there is a leak. Pair the Water Main Shut-Off with a few Leak Sensors, and configure your Hub to automatically close the valve when water is detected.
