6. Setup and Installation
Follow these steps to install the replacement button:
- Measure Original Button: Before starting, carefully measure the length of your existing toilet tank button and its rods. This replacement button has a 76mm body length and 76mm rods. Ensure these dimensions are suitable for your toilet.
- Disassemble Old Button: Remove the old flush button from your toilet tank lid. This usually involves unscrewing or unclipping it.
- Assemble New Button: Insert the moon-shaped and sun-shaped buttons into the main button body.
- Attach Rods: Insert the two button rods into their respective slots on the flush valve mechanism. The rods can be cut to the required length using a suitable tool if they are too long for your specific toilet tank depth.
- Secure Button: Place the assembled button body into the opening on the toilet tank lid. Ensure the rods align correctly with the flush valve.
- Tighten: Use the provided black screw and plastic screwdriver to secure the button assembly from underneath the tank lid. Do not overtighten.
- Test Functionality: Press both the partial and full flush buttons to ensure they operate the flush valve correctly and return to their original position smoothly.

7. Operation
The TECETOOL Dual Flush Valve Replacement Button offers two flushing options to conserve water:
- Partial Flush (Quick Flush): Press the smaller, moon-shaped button for a reduced water flush (typically 3 liters). This is suitable for liquid waste.
- Full Flush: Press the larger, sun-shaped button for a complete water flush (typically 6 liters). This is suitable for solid waste.

8. Maintenance
To ensure optimal performance and appearance of your flush button:
- Clean the button surface regularly with a soft, damp cloth.
- Avoid using abrasive cleaners, harsh chemicals, or scouring pads, as these can damage the finish.
- Periodically check that the button operates smoothly and is securely fastened.
9. Troubleshooting
If you encounter issues with your TECETOOL Dual Flush Valve Replacement Button, consider the following:
- Button Does Not Fit: Double-check the measurements of your original button and compare them with the specifications in Section 5. This button is specifically for 76mm length and compatible Roca flush valves.
- Flush Not Activating: Ensure the button rods are correctly aligned with the flush valve mechanism and are of the appropriate length. If the rods are too long, they may prevent the button from fully depressing. If too short, they may not engage the valve.
- Button Sticks: Verify that the button assembly is not overtightened and that there are no obstructions preventing smooth movement.
- Missing Parts: If any parts were missing upon arrival, please contact customer support immediately.
