Below is a guide to understanding Phyn Leak Alerts

Note: The flow and elapsed time threshold values for the Flow Alerts shown below are default thresholds based on population averages. However, most homes and households have home-specific variations that emerge over time. As such, Phyn’s AI learns these unique patterns in what is referred to as a “home-specific model” and these thresholds are dynamically updated regularly. Typically, these patterns are observed and initially learned within the first 21 days (about 3 weeks). Phyn’s self-learning AI continues to enhance its home-specific knowledge base nightly with observations over the past 24 hours.

This means that if a Phyn-protected household continuously uses more water, its dynamic thresholds will be extended. Conversely, if a household continuously uses less water, its dynamic thresholds will then be shortened.

I got a "Low Flow Alert". What does that mean and what should I do? By default, during the initial learning period, Phyn sends you an alert when it has noticed an unusual flow of water in your home that has lasted at least 20 minutes and has used at least 6 gallons of water. As referenced above, these thresholds will dynamically and continually adjust for each Phyn-protected home based on that household’s unique water usage patterns.

If Phyn's Auto Shutoff is enabled, you will receive a second alert 10 minutes after the first alert is issued. If you do not respond to this second alert within 15 minutes, Phyn will shut your water off.

You can view more information about your alert in the "Alerts" section of the app on the top right of the screen. If the alert shows up in the "Active" panel, that means that the water activity is still going on and has not resolved itself. If the alert appears in the Resolved panel, the unusual water use has concluded and you will see when it was "last detected". For instance, if you left a hose running and then turned it off after an alert has been issued, it would now appear as resolved.

Typically a Low Flow Alert is the result of minor activity, such as a faucet dripping or left open, or a spigot left on. Another frequent cause of this alert is a leaking toilet flapper, which may result in a constant filling of your toilet tank.

"Ultra-Low-Flow" (Applicable to the Phyn Plus Only): Phyn’s AI is constantly learning and improving to more accurately detect lower flow rates while maintaining our industry-leading ability to minimize false alarms. Our leak (or, unusual flow) detection system is now up to 10x more sensitive to lower flow rates than previous models. This enhanced capability now allows for unusual ultra-low-flow activities to be detected soon after they arise rather than waiting for the nightly plumbing checks. This now closer to real-time enhancement will help you mitigate water loss and potential damage even earlier than before while improving your troubleshooting ability. There are many home factors such as noise in the plumbing system (e.g., broken PRV), intended ultra-low-flow activities, etc. that are rare but possible that could affect the sensitivity. However, in a majority of environments, Phyn Plus is now capable of detecting, in near-real-time, ultra-low-flow events as low as 0.01gpm flow rates.

If you are at your property, you should listen for water flow and do a visual inspection of your property. If you cannot find the source of the alert you can run a series of Plumbing Checks to try to isolate the source of the leak. To do this, turn off the water from a faucet or toilet manually by turning the stop located at the fixture. Run a Plumbing Check from the Phyn app, and if the result comes back normal, you have found the source of the issue. If the result comes back with a problem, you can move on to the next fixture. If you cannot find the source of the leak in this manner, we suggest you consult your plumber.

If you are not at your property, we suggest you turn the water off remotely using the Phyn app until you can get on-site, or call your plumber for assistance.

If you know the source of the alert and it is not a leak, help teach Phyn by clicking on the alert and then selecting Tell Us at the bottom of the screen. The more feedback you provide through the Phyn App, the faster the Phyn App will learn and will stop sending you alerts the next time that activity occurs.

I got a "Medium Flow Alert". What does that mean and what should I do?

Phyn sends you an alert when it has noticed an unusual flow of water in your home that has lasted at least 20 minutes and has used at least 60 gallons of water.

If Phyn's Auto Shutoff is enabled, you will receive a second alert 5 minutes after the first alert is issued. If you do not respond to this second alert within 5 minutes, Phyn will shut your water off.

You can view more information about your alert in the "Alerts" section of the app on the top right of the screen. If the alert shows up in the "Active" panel, that means that the water activity is still going on and has not resolved itself. If the alert appears in the "Resolved" panel, the unusual water use has concluded and you will see when it was "last detected". For instance, if you left a hose running and then turned it off after an alert has been issued, it would now appear as resolved.

Typically a Medium Flow Alert is the result of a leaking toilet flapper, which may result in a constant filling of your toilet tank. If you are at your property, check to make sure that the chain in your toilet's ballcock assembly is not caught under the flapper (rubber valve at the bottom of the tank), or on the flush handle. Another likely issue is your water heater's T&P valve, which tends to wear out after 5 years. Check the valve, located on the top or side of your water heater 6" below the top. If the valve is leaking call your plumber. Also check the drip pan under your water heater to ensure that it's not overflowing.

If you cannot find the source of the alert you can run a series of Plumbing Checks to try to isolate the source of the leak. To do this, turn off the water from a faucet or toilet manually by turning the stop located at the fixture.

I got a "High Flow Alert." What does that mean and what should I do? Phyn sends you an alert when it has noticed an unusually high flow rate of water in your home that has lasted at least 3 minutes or has used at least 50 gallons of water.

If Phyn's Auto Shutoff is enabled, you will receive a second alert 2 minutes after the first alert is issued. If you do not respond to this second alert within 2 minutes, Phyn will shut your water off.

You can view more information about your alert in the "Alerts" section of the app on the top right of the screen. If the alert shows up in the "Active" panel, that means that the water activity is still going on and has not resolved itself. If the alert appears in the "Resolved" panel, the unusual water use has concluded and you will see when it was "last detected". For instance, if you left a hose running and then turned it off after an alert has been issued, it would now appear as resolved.

Typically a High Flow Alert is the result of a broken pipe or damaged supply line (to an ice maker or washing machine). If you are at your property, check to see if you can hear or see water. Sometimes Phyn can mistake irrigation or a pool filling for a high flow leak if it hasn't learned your home's patterns yet. If you don't know what is causing this alert, turn off your water from the Phyn app and call your plumber immediately. If you are not at your property, we suggest you turn the water off remotely using the Phyn app until you can get on-site, or call your plumber for assistance.

If you know the source of the alert and it is not a leak, help teach Phyn by clicking on the alert and then selecting Tell Us at the bottom of the screen.
