Phyn Plus

What is it & how does it work?

Phyn Plus measures tiny changes in water pressure — 240 times a second — to alert homeowners the moment a leak is detected, mitigate costly damage through automatic shutoff, and diagnose potential problems in plumbing systems before they become an issue. This single device, installed by a plumbing specialist, enables homeowners to manage their water throughout the entire home, even when they’re away.

HD Pressure Sensing

Phyn uses patented, high-definition pressure wave sensing to catch plumbing issues ranging from faucet drips to pinhole leaks to frozen pipe bursts.


Phyn learns about your plumbing system as soon as it’s connected and gets to know the unique signatures of each fixture better over time to recognize the subtle differences between a bath filling and pipe leaking.

Built-In Shut Off Valve

Phyn Plus can turn off water automatically in the event of a catastrophic leak, protecting homeowners from costly damage.

Plumbing Checks

Daily diagnostic “Plumbing Checks” notify homeowners of unsafe pressure levels and potential leaks before they become larger issues.

Professional Installation

Phyn Plus is installed by a member of the Uponor Pro Squad, a nationwide network of expertly-trained plumbers and water specialists.

Leak Alerts

Real-time mobile notifications alert homeowners to potential leaks and give them the power to turn off their water remotely using the Phyn app.

Decade in the Making

Phyn’s technology has been honed in the labs of the University of Washington and Belkin, the hands of plumbers, and the homes of beta testers.

One Device, Whole Home

One device monitors the entire home’s water from a single location on the main water line.
