Phyn sends a Malfunctioning PRV Alert when it detects unstable water pressure in a home with a Pressure Reducing Valve (PRV) installed.
A PRV is designed to keep incoming city water pressure steady. If Phyn detects pressure repeatedly rising and falling outside the normal range, it likely means the PRV is not working properly.
Why this matters
A malfunctioning PRV can allow pressure spikes that may:
Stress or damage pipes
Increase the risk of leaks
Shorten the lifespan of water-using appliances, such as dishwashers and washing machines
What you should do
Tap the alert in the Phyn App to review guidance and pressure details
Contact a licensed plumber to inspect and repair or replace the PRV as soon as possible
A properly functioning PRV is an important part of maintaining a leak-free home and protecting your plumbing system.
After the repair
Once your PRV has been repaired or replaced, it may take up to 48 hours for pressure readings in the Phyn App to reflect the change.
