Smart Water Assistant
The self-installed water monitor that goes under a single sink, immediately notifies you if a leak is detected anywhere in your home, and provides detailed insights into how each fixture in your home uses water.

Never worry about hidden leaks again
From drip leaks to catastrophic bursts and everything in between, Phyn gives you the tools to ensure that your home is watertight. And at the first sign of an issue, Phyn sends SMS or push notifications and can connect you to a local plumber in minutes.
See your water and save
Track and view your water use daily and monthly to get ahead of your water costs, and see how your home compares to others. Over time, Phyn learns your system and communicates your water usage down to each fixture.
Avoid frozen pipes
Phyn’s patented pressure sensing technology sees the ice crystals forming in your pipes well before your pipes ever have a chance to freeze over and burst, giving you time to time to take action and avoid damage.
How Phyn works
Phyn measures microscopic water pressure changes in high definition — 240 times every second — to recognize the unique voice of each fixture in your home. So when you run a faucet, Phyn knows it’s a faucet. And if that faucet leaks, Phyn lets you know.

Frequently asked questions
Some multi-family dwellings that have individual plumbing lines and meters for each unit are compatible with Phyn. Typically a Pressure Regulating Valve (PRV) will also need to be installed in each unit. If you have questions about whether your home will work with Phyn, contact us at 877.749.6792.
Absolutely! There are many homes with wells that are using Phyn Smart Water Assistant
Phyn alerts of leaks and other plumbing issues via SMS and push notification from the Phyn app, available for iOS and Android devices.
Phyn Smart Water Assistant will detect leaks in your water delivery system such as pipe bursts, toilet flapper leaks, and leaks in supply-line hoses to clothes and dishwashers. Phyn will also alert you if your water has been running longer than normal. Using the “Plumbing Check” feature, Phyn Smart Water Assistant can find tiny drip leaks and pinhole leaks. Phyn will not catch roof leaks and leaks or stoppages in outflow lines (e.g. a clogged sink or sewer line).
Phyn works with Amazon Alexa, Google Home and IFTTT (If This Then That).
Plumbing Check is a diagnostic test that you can run at any time to find tiny drip leaks and pinhole leaks in your plumbing system. In order to run a Plumbing Check with Phyn Smart Water Assistant, you must turn off your water at the main, go into the Phyn app and initiate a Plumbing Check test. These typically last 2-5 minutes and return results as soon as the test is completed.
Phyn Smart Water Assistant learns each of your home’s fixtures over time. It applies the knowledge of the tens of millions of water events it has seen in the past to understand the usage in your home. But sometimes, it doesn’t understand a particular fixture and may label it incorrectly. To teach Phyn, you can re-label the event and help it correct itself. The more you label events, the more accurate Phyn will be for you in reporting water usage.
When a leak or abnormal usage happens and you get an alert, Phyn Smart Water Assistant gives you the option to contact a plumber within minutes from the Phyn app through our partnership with HomeAdvisor.
Pressure Reducing Valves are a bell shaped device on the main water line that controls the pressure of the water going into your home. PRVs protect your home from high pressure spikes that can wear out your pipes and damage fixtures over time. Some municipalities require PRVs by code, and others do not. We recommend that everyone get a PRV in order to elongate the lifespan of their plumbing. If you do not have a PRV, Phyn will take much longer to become accurate at detecting leaks and identifying fixtures correctly. In the meantime, you will be able to use Phyn’s Plumbing Check feature to detect leaks manually.
HomeKit support is on the roadmap and being worked on. We'll let you know when it will become available.
