Flow-Tech: Start Up Verifying Proper Installation and System Readings

This guide explains what to look for on the Flow-Tech display during startup to confirm the system is installed correctly and operating as intended.

 

What Happens During Startup

When the Flow-Tech unit powers on, it runs an internal startup sequence. During this process, the screen will scroll voltage and amperage readings across the display.

These readings confirm that the system has:

  • Proper grounding

  • A complete circuit

  • The ability to transmit signal through the plumbing system

Understanding Volts and Amps on the Display

During startup, you will see:

  • Volts

  • Amps

The system uses capacitance and resistance to create what is known as a gamma match, which allows the signal to be driven effectively through the water.

A rising amperage reading indicates the system is grounding correctly.

What Amperage Tells You

Amperage is the most important indicator during startup.

General guidelines:

  • Amps climbing during startup indicate a good installation

  • Higher amperage suggests better grounding

  • Very low amperage indicates a grounding issue

If amperage does not increase, the system will not perform as expected.

Acceptable Amperage Ranges

  • Strong grounding
    Higher readings indicate excellent grounding and signal propagation

  • Marginal grounding
    Lower readings suggest the system may still operate, but signal strength may be reduced

  • Poor grounding
    Very low readings will trigger an error and require correction

If amperage is too low, the unit may display a message instructing you to check the installation or grounding.

Error Messages and What They Mean

If grounding is insufficient, the display may show:

  • Check installation

  • Check ground

This indicates the signal cannot be properly driven through the system.

When this occurs:

  • Verify grounding connections

  • Check the water heater ground

  • Confirm conductive metal contact

  • Reposition grounding points if needed

Why Grounding Matters

Flow-Tech relies on two effective paths to ground to transmit the radio frequency signal through the water.

A properly grounded system ensures:

  • Strong signal throughout the home

  • Consistent system performance

  • Reliable scale control

Documenting Startup Readings

Taking photos of the display during startup is strongly recommended.

Photos help:

  • Confirm proper installation

  • Provide documentation for support

  • Assist with troubleshooting if issues arise later

These photos can be shared with Plumber’s Choice Water support if needed.

When to Contact Support

Contact support if:

  • The unit displays a grounding error

  • Amperage readings remain very low

  • You are unsure about grounding points

  • The system does not complete startup normally

Key Takeaway

Startup readings confirm whether the Flow-Tech system is installed correctly. Proper grounding and healthy amperage readings ensure the signal can travel throughout the plumbing system.
