Yes. Phyn Smart Water Assistant will work even if your home does not have a Pressure Regulating Valve (PRV), but there are a few important things to know.
What Phyn can do without a PRV
If your home does not have a PRV, you can still:
Monitor your water pressure in real time in the Phyn app
Run manual Plumbing Checks to proactively check for leaks
Detect water usage events and see estimated water consumption
Receive alerts for unusual water activity
What to expect without a PRV
Homes without a PRV often have more variable water pressure. As a result:
Phyn may take longer to learn your home’s water usage patterns
You may see more false alerts during the learning period
Fixture-level water usage accuracy may be reduced at first
Providing feedback in the app by labeling alerts and confirming fixtures will help Phyn improve faster.
Why a PRV improves Phyn’s accuracy
A PRV helps stabilize incoming water pressure and reduces background pressure “noise” from city pipes and nearby homes. This makes it easier for Phyn to clearly identify when water starts and stops flowing.
In simple terms, Phyn works best in a quieter, more stable pressure environment.
Our recommendation
While Phyn works without a PRV, we recommend installing one if your home does not already have it. A PRV not only improves Phyn’s performance, but also helps protect your plumbing system by reducing the risk of leaks, appliance damage, and pressure-related wear.
