4. Operation
The Dreyoo Bathtub Pop-Up Drain Stopper operates with a simple push mechanism:
- To Close: Press down firmly on the top of the drain stopper until it clicks into the closed position. This will seal the drain, allowing the tub to fill with water.
- To Open: Press down firmly on the top of the drain stopper again. It will pop up, opening the drain and allowing water to flow out.
The pop-up design allows for convenient foot operation during showering.
5. Maintenance
Regular cleaning and maintenance will ensure the longevity and proper function of your drain stopper:
- Cleaning: Periodically remove the drain stopper from the drain. Clean any accumulated hair or debris from the rubber gasket and the stopper mechanism using a mild cleaner and a soft brush.
- Gasket Inspection: Inspect the rubber gasket for any signs of wear, cracks, or damage. A damaged gasket can lead to leaks.
- Reassembly: After cleaning, ensure all components are reassembled correctly, especially the star shape lock washer, to maintain a tight seal.

6. Troubleshooting
If you encounter issues with your drain stopper, consider the following:
- Drain Leaks: If the drain stopper is leaking, ensure the star shape lock washer is correctly installed and tightened. Check the rubber gasket for any damage or misalignment.
- Stopper Not Popping Up/Down: Verify that the internal spring mechanism is not obstructed by debris. If the mechanism appears broken, replacement may be necessary.
- Improper Fit: If the stopper does not fit securely, double-check that you have used the correct 3/8'' or 5/16'' threaded stud for your bathtub drain.
- Discoloration: Some discoloration may occur over time depending on water quality and cleaning products used. Regular cleaning with non-abrasive cleaners can help maintain its appearance.
