Buoy® Whole Home Water Controller installs on your water line


Installation Configurations 

What is standard? In less than two hours, a professional will install the Buoy Whole Home Water Controller on 4-13” of exposed pipe that has at least 6” inches clearance from walls, pipes, and appliances, without needing extra pipe or fittings to do the job. For flex line installations, the plumber will secure Buoy to a 20x20x10 space on the wall that’s less than two feet from Buoy’s connection to your flex line.

Non-standard installations can require:

  • Cutting into walls or digging up pipes

  • Reworking your pipes to create space for the Controller

  • New copper pipe, pressure regulators, or similar supplies

  • More than two hours of time

Interior vertical installation

Interior vertical installation

The Controller will go inside or outside your house in a spot above ground that's always accessible. It doesn’t need to be plugged in (just recharge the battery about once a year), and can be installed vertically or horizontally, with either copper pipe or flexline.

The Buoy App 

Once the Controller is installed and conneceted to your home WiFi network, it gets to work immediately, flexing its machine-learning muscle to analyze your water data. With a subscription, you can see your household water use and, when the Controller detects abnormal water usage, shut off your water remotely and automatically. It takes two weeks for the Controller to learn your home’s water signature. After two weeks, it will start categorizing your water usage, send you leak alerts, and, if you’ve enabled automatic shutoff, turn off your water when there’s a problem.
