Pressure Regulating Valves

Pressure regulating or reducing valves (PRVs) are installed on the main pipe where the water enters the home. They can be essential to the health and maintenance of the plumbing system.

Municipal water providers often increase water pressure to reach homes spread across large distances. Over time water at high pressure levels can lead to the breakdown of pipes and plumbing fixtures. PRVs are installed to bring pressure down to mandated levels and are common in newer homes.

We recommend that all homes have PRVs. If your home does not have a PRV or if yours is malfunctioning, you will be able to monitor your water pressure in real-time from the Phyn app and perform manual Plumbing Checks to proactively check for leaks. However, Phyn will require a much longer timeframe to achieve a high level of accuracy.

If you have an outlet and have your garbage disposal already plugged into it you can perform a simple test. Unplug the disposal from the outlet and then plug your phone into this outlet. If it shows that it is charging it is an unswitched outlet. If it does not begin to charge, it is likely a switched outlet. Turn on the switch that controls the disposal under your sink and if your phone shows it is now charging that confirms that it is a switched outlet.
We recommend having a licensed electrician convert one of your outlet receptacles to have it unswitched.
You can purchase an outlet adapter at any local hardware store to turn a single outlet into a double (or multi) outlet.
Phyn is designed to monitor your whole home from a single location. As long as there is easy access to a hot line, a cold line, and an available electrical outlet you can install Phyn under any sink you choose.

The Wi-Fi signal must be available at the location where the Phyn device is installed. To improve the signal you can move your router closer to the installation location or consider buying an extender.
