Buoy® installs on your water line


Installation Configurations 

Standard installation by a Buoy plumber is included in the purchase price.

Buoy will go inside or outside your house in a spot above ground that's always accessible. Buoy can be installed vertically or horizontally, with either copper pipe or flexline. We include the optional waterhorn accessory, which allows installation on only four inches of pipe, in your purchase so it's there if the plumber needs it. If it isn't used, just contact us for a prepaid shipping label and return it for a refund.

What You'll Need

  • WiFi network using Wi-Fi 802.11b/g/n @ 2.4GHz
  • Accessible main water line for a single residence (not a shared meter) 
  • Phone or tablet with iOS 8 or later, or Android 4.4 or later

In the Box

  • Your Buoy device

  • Installation by a licensed plumber

  • Rechargeable battery

  • Battery charger, adapter, and power cord (indoor use)

  • Prepaid return envelope for waterhorn

Installation Hardware: 

  • Rubber gasket rings (6)

  • Meter couplings (2)

  • Optional waterhorn


Including the waterhorn with your purchase saves time because it's there for the plumber if necessary— no need to schedule a second installation while you order a waterhorn. If you don't need it,  just contact us for a prepaid shipping label and return it within 15 days of Buoy's installation for a full refund.

If you're sure your installation won't need a waterhorn, please contact Support. We think it's best to have it on hand just in case, since you will be responsible for any additional plumbing charges if a second installation appointment is required.


The Buoy App 

Once your Buoy device is installed and conneceted to your home WiFi network, it gets to work immediately, flexing its machine-learning muscle to analyze your water data. From the moment you’re connected, you can see your household water use and, in an emergency, shut off your water from a button in the app.
