Installing a Phyn Plus in a Well Home

Last updated on 30 Jan, 2026

When installing a Phyn Plus in a well home, it’s important to place the device correctly within your plumbing system to ensure accurate monitoring and reliable performance. Use the guidelines below when planning your installation.

Recommended installation order

  1. Well pump.
    The Phyn Plus must be installed downstream of the pressure tank and should never be installed between the well pump and the pressure tank.

  2. Pressure tank.
    Install the Phyn Plus downstream of the pressure tank. If possible, leave a few feet of pipe between the pressure tank and the Phyn Plus to reduce turbulence in the water.

  3. Sediment filter.
    The Phyn Plus should be installed after the sediment filter so grit or sand does not pass through the device.

Water conditioners and filtration systems

Water conditioners and filtration systems include acid neutralizers, reverse osmosis systems, water softeners, and whole-home filtration systems. There are two installation options, each with different considerations.

Option one: Installed upstream (before) the Phyn Plus

  • You will not receive unusual water activity alerts for these fixtures

  • Water usage from the conditioners or filters will not be monitored by Phyn

Option two: Installed downstream (after) the Phyn Plus

  • Phyn will detect water usage from these fixtures

  • You may receive frequent unusual water activity alerts during the learning period

  • You will need to respond to alerts and provide feedback in the app so Phyn can learn your system

Important notes for well homes

  • If you have a water softener, familiarize yourself with its regeneration cycle

  • Regeneration cycles occur periodically and may trigger alerts or cause the water to shut off if Auto Shutoff is enabled

  • During the learning period, carefully identify water usage events related to these fixtures

  • Some water-using systems have motors that can be damaged if they run without water

  • This may include water softeners, conditioners, acid neutralizers, RO filters, whole-home filtration systems, and irrigation systems

  • In some cases, water quality can also be affected if these fixtures operate without water

Before enabling Auto Shutoff, confirm that your fixtures can safely operate without water and that their motors will not be damaged if water flow is interrupted.
