Troubleshooting

If you encounter issues with your RESTMO Water Flow Meter, refer to the following common problems and solutions:

Water Measurement Not Correct

• Ensure the counting unit (liter/gallon) is correct.
• Maximize the faucet water flow (> 1 GAL/MIN).
• Reset the TOTAL mode and use the TOTAL mode to measure the water flow.

LCD Screen Does Not Work Properly / Is Dead

• Replace with a brand-new battery and install it with correct direction.
• DO NOT moisten the battery and battery compartment. Keep your hands dry.
• If the LCD screen has condensation, leave it under sunshine for a period of time; the fog will disappear.

Water is Leaking

• Check if the filter washer is clean and undamaged.
• Check if the filter washer is in place.
• Ensure connections are hand-tight.
• Verify proper connection to a 3/4" NH faucet thread.

Water Pressure is Restricted

• Clean or replace the filter washer regularly.
