Phyn Plus
Smart water assistant + shutoff
Phyn Plus uses patented, high-definition pressure wave analysis to alert you the second a leak is detected, mitigate costly damage through automatic water shutoff and teach you about your water use.

The Most Accurate Leak Detection Solution

In a recent third party study, Phyn Plus was found to be the most reliably accurate whole home leak detection solution across multiple flow thresholds.

Phyn Plus uses patented, high-definition pressure wave analysis to alert you the second a leak is detected, mitigate costly damage through automatic water shutoff and teach you about your water use.
Measuring pressure waves. 240 times a second.
The science behind Phyn was developed in the labs of the University of Washington and at Belkin. Phyn Plus measures tiny changes in pressure 240 times every second to understand the unique voice of each water fixture in your home. This allows Phyn understand the subtle differences between a running bath and a burst pipe.
High Def Ultrasonic Flow Sensor
Phyn Plus is the only connected water monitor to offer an ultrasonic flow sensor, exclusively built by Badger Meter, with no moving parts, ensuring accuracy and durability over the long haul. Other water monitors use turbine flow sensors with rotating discs that are less accurate, and often degrade over time or can get stuck by debris or buildup.
One device. Whole home protection.
Other water monitors require you to place multiple sensors around the home where you think leaks are likely to occur. One Phyn Plus in a single location is all you need to monitor your entire home’s water system for leaks.
Phyn needs:
  • ...
    Main water supply line 1 1/4″ or smaller

Frequently asked questions
Installation typically takes one to two hours, and depends on the location of your main water supply.
We recommend that you use a licensed plumber to install Phyn Plus. The main water line to your home will be cut where Phyn Plus is installed. We have partnered with the Uponor Pro Squad to bring you local plumbers that have expertly-trained to ensure that Phyn Plus is installed properly, and to meet all local code requirements. You can also use your own licensed plumber.
Yes, you can use your own plumber to install Phyn Plus. We have included instructions that you can give to them in the Phyn Plus box. They must follow these instructions carefully to ensure proper installation.
We recommend that Phyn Plus be installed on pipes no larger than 1 ¼ inches.
Phyn Plus has 1” NPSM male threaded ends. When you purchase online, we include connectors in the box: 3/4″ Water Meter Coupling Complete with Gasket, 1″ NPSM, 2-1/2″ Length, 3/4″ NPT.
Absolutely! Phyn Plus has been installed on many homes with wells.
Once installed, Phyn will learn how you normally use water in your home. After this initial learning period, which is different for every home, it will unlock the ability to turn off your water automatically in the event of an abnormally high flow. Phyn will always send you an alert when a potential leak is detected, and will give you the power to turn off your water remotely using the free Phyn app.
If you have a fire sprinkler system that is standalone and is on its own branch of pipes (not integrated into the same pipes that deliver water to your fixtures) then Phyn Plus can be installed as long as it is placed after where your sprinkler line branches off. Phyn Plus should not be installed where it will interfere with your fire sprinkler operation.
Yes. You will need an electrical outlet within 15 feet of where the device is installed (we recommend a GFCI equipped outlet). Phyn Plus comes with a 15-foot power cord.
Phyn Plus is intended for single family homes, with individual water meters. However, some multi-family dwellings that have individual plumbing lines and meters for each unit are compatible with Phyn Plus. Typically a PRV will also need to be installed in each unit as well.
Phyn Plus will remain in the state it was in when the power is lost. It will not turn off your water unless it was already in the closed position. In the event of power loss, you can use the manual shut off tool included on the mounting bracket to turn your water on and off.
Yes. If your Phyn Plus device is able to be installed so that it is “before” your irrigation lines, then your irrigation will be monitored for leaks and usage.
Phyn Plus is installed on the main water line, right after your water meter or where the water enters your home and before your pipes split off to the various rooms and fixtures of your home.
If your installation location is out of the range of your home’s Wi-Fi, Phyn Plus has a universal antenna port located on the bottom of the unit. Any external antenna can be plugged into this port to improve your Wi-Fi reception.
