5. Setup and Installation
Installation of the Frizzlife MWT3 is designed to be straightforward, utilizing 1/4 inch quick-connect fittings. Follow these steps carefully:
Step-by-Step Installation
- Prepare the Ball Valve and T-Adapter: Connect the provided ball valve to the T-adapter. Ensure a secure fit.
Image: Step 1 - Connecting the ball valve and T-adapter.
- Attach Fitting Set to Tank: Securely attach the assembled ball valve and T-adapter fitting set onto the top of the MWT3 tank.
Image: Step 2 - Attaching the fitting set to the tank.
- Cut RO System Outlet Tubing: Using the provided blade, cut the outlet tubing of your existing RO system cleanly and evenly. This cut should be made at a convenient location where the MWT3 tank can be easily integrated.

6. Operating Instructions
The Frizzlife MWT3 Mini Pressure Water Tank operates automatically in conjunction with your tankless RO system. Once installed, it requires no manual operation.
- The MWT3 tank maintains a small reserve of pressurized water, which is immediately available when you open your RO faucet or refrigerator dispenser.
- This immediate water supply eliminates the typical initial delay experienced with tankless RO systems.
- The tank is designed to dispense approximately 200ml of water before the RO system's pump activates to refill the tank, ensuring a smooth and consistent flow.
- It also helps to stabilize water pressure, reducing any pulsations that might occur in your RO system.

7. Maintenance
The Frizzlife MWT3 Mini Pressure Water Tank is designed for durability and requires minimal maintenance. However, regular checks can ensure its continued optimal performance:
- Leak Inspection: Periodically inspect all quick-connect fittings and tubing for any signs of leaks. Address any leaks immediately by turning off the water supply and re-seating connections.
- Pressure Check: The tank's internal air pressure should be maintained between 6 and 9 PSI (pounds per square inch) when empty. You can check and adjust this pressure using a standard bicycle pump with a pressure gauge. If you do not have a precise pressure gauge, it is recommended to leave the factory-set pressure as is.
- Cleaning: The exterior of the tank can be wiped clean with a damp cloth. Do not use harsh chemicals or abrasive cleaners.
8. Troubleshooting
If you encounter issues with your Frizzlife MWT3 Mini Pressure Water Tank, refer to the following troubleshooting guide:
No Water Flow or Low Pressure
- Check Connections: Ensure all quick-connect fittings are securely seated and that tubing is fully inserted.
- Verify Ball Valve Position: Make sure the ball valve connected to the tank is fully open.
- RO System Functionality: Confirm that your main RO system is functioning correctly and producing water. The MWT3 tank relies on the RO system for its water supply.
- Tank Pressure: Check the internal air pressure of the MWT3 tank. If it is significantly below 6 PSI, it may not be able to dispense water effectively. Adjust if necessary (refer to Maintenance section).
Leaks
- Turn Off Water: Immediately turn off the main water supply to prevent further leakage.
- Inspect Fittings: Carefully inspect all quick-connect fittings. Remove and re-seat any tubing that appears loose or improperly inserted. Ensure tubing ends are cut cleanly and straight.
- Check for Cracks: Inspect the tank and fittings for any visible cracks or damage. If damage is found, the component may need replacement.
