Meet Buoy

Almost every home loses 10% of its water to leaks that can be easily fixed


The Buoy device connects to your home’s water line, and sends information to the Buoy app. From there, you’ll see where you’re using water, and can shut off water remotely if there’s a leak. Peace of mind, predictable bills — and you can keep your lawn.

One device for your entire home.



Installs on your water line

A qualified plumber will install your Buoy at your home’s main water line, which sits after the water main on the street but before water line branches throughout your home and yard. 


Installation Configurations 

A plumber installs your Buoy inside or outside your house in a spot that's always accessible. Buoy can be installed vertically or horizontally, with either copper pipe or flexline. If you’re short on space between pipes, the optional waterhorn accessory only needs four inches.

The Buoy App

The app is where your water data comes to life. See how many gallons you use to shower, do laundry, and keep your lawn green. Chances are, you’ll see something else: leaks. The app will show the 10 percent of water that homes typically lose to slow leaks, and if there’s a sudden or potentially damaging leak, you can shut off your water from a button in the app.

Buoy's Shutoff is a Game Changer: 
Homeowners’ insurance companies pay $9.1 billion in water damage claims annually, and industry studies estimate that 93 percent of that could be avoided by using a leak detection device with remote shutoff.

On the Screens:

  • At-a-glance data for your entire home
  • Water use by category
  • Leak alerts
  • Remote shutoff button
