What is Auto Shutoff?
Auto Shutoff is a feature that allows Phyn Plus to automatically shut off the water to your home when certain water events occur, such as a burst pipe.
When is Auto Shutoff enabled?
Auto Shutoff is disabled by default while Phyn learns your home’s water usage patterns.
Auto Shutoff becomes available after Phyn has gathered enough data from your home:
After 700 water events for most homes
After 1,000 water events for homes with fixtures such as:
Irrigation systems
Pool fillers
Water softeners
RO filters
Whole-home filtration systems
Whole-home humidifiers
Acid neutralizers
Iron filters
Ice makers
Regardless of the number of water events, Auto Shutoff will automatically become available after 21 days
In the Phyn App, go to Menu > Settings > Auto Shutoff to view the progress indicator labeled “Auto Shutoff xx% Complete”.
When the indicator reaches 100%, Phyn has finished learning your home’s water usage. You will receive an SMS notification letting you know Auto Shutoff is ready to be enabled.
Even before Auto Shutoff is enabled, you will continue to receive alerts for unusual water activity.
What happens when Auto Shutoff is triggered?
If Auto Shutoff is enabled and Phyn detects a qualifying water event:
You will receive an alert in the app
If you do not respond within the specified time window, Phyn will automatically shut off your water
You can turn your water back on at any time using the Phyn App or the Phyn Plus device
Important safety note
Water should not be shut off while certain motorized appliances are operating.
Some (but not all) of the following fixtures may have motors that can be damaged if they run without water, or may impact water quality:
Water softeners
Water conditioners
Acid neutralizers
RO filters
Whole-home filtration systems
Irrigation systems
Before enabling Auto Shutoff, confirm that your fixtures can safely operate without water and do not contain motors that could be damaged.
How does Auto Shutoff get unlocked?
Phyn builds a personalized model of your home by analyzing water pressure, flow, and fixture behavior over time. Because every home is different, the learning period varies.
You can help Phyn learn faster by providing feedback on alerts:
Tap an alert
Select Tell Us
Once Phyn reaches a high confidence level that shutoffs will only occur during emergencies, Auto Shutoff becomes available.
How do I disable Auto Shutoff?
Auto Shutoff can be disabled through the Phyn App, with some exceptions.
Important:
Phyn Plus customers with homeowners insurance through certain insurance partners cannot permanently disable Auto Shutoff. This policy is set by the insurance provider. These customers may only pause Auto Shutoff for up to 24 hours. Auto Shutoff and Offline Leak Protection are required for some insurance programs, including AIG.

Tap the Menu icon.
Tap Settings.
Under Features, locate Auto Shutoff.
Tap Auto Shutoff>Offline Leak Protection.
When prompted, confirm by tapping Disable Auto Shutoff.
Use caution when disabling Auto Shutoff, as your home will be unprotected during this time.
Can I pause Auto Shutoff?
Yes. Auto Shutoff can be paused for 30 minutes up to 24 hours. After the selected time period, Auto Shutoff will automatically re-enable.
