The Water Main Shut-off

Add Z-Wave magic to your existing plumbing.


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


Prevent Leaks

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.


Such Convenience

Install in a vacation or second home to conveniently shut off the water when going out of town. Configure your Hub to automatically turn it on or off depending on your GPS coordinates! For indoor use only!


Use Anywhere

Use on any quarter-turn ball valve up to 1-1/2" in size. Automate your water boiler, Radiant heat system, or something else ancient you never thought you could automate!




Single Tool Installation

Installs with just a single Phillips screwdriver. No pipe wrench or fairy dust required.


No Plumber Needed

Installs on top of your existing valve - for indoor use only!


Extra-long Power Cord

Find power even in large utility rooms. No need to MacGyver a power supply.


Built-in Range Extender

Boost Z-Wave coverage in your home for more reliable coverage (especially in the mechanical room.).


Powerful Motor

Works on quarter-turn ball valves up to 1-1/2".


Small Power Supply

As former installers we know how important clean, easy to read documentation is. We created Dome from the ground up with the idea that sensors should work with any hub, and they should be easy to modify and troubleshoot.
