Buoy® installs on your water line


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.
