5. Setup and Installation
This replacement kit offers a direct, hassle-free installation process for Glacier Bay Model 83SGB dual flush toilets. No special tools or advanced plumbing expertise are required.
Installation Steps:
- Turn off Water Supply: Locate the water shut-off valve behind or near your toilet and turn it clockwise until the water flow stops completely.
- Drain the Tank: Flush the toilet to empty the water from the tank. Hold the flush lever down until the tank is as empty as possible.
- Remove Tank Lid: Carefully lift the toilet tank lid and set it aside in a safe place.
- Access the Flush Valve: The dual flush mechanism, which includes the seal, is typically a central cylinder in the tank. Gently twist or unclip the flush valve assembly to remove it from its base. Refer to your specific Glacier Bay toilet model's diagram if unsure.
- Remove Old Seal: Once the flush valve assembly is removed, locate the old rubber seal at its base. Carefully pull off the old, worn-out seal.
- Install New Seal: Take one of the new seals from the kit. Ensure it is clean and free of debris. Carefully stretch and fit the new seal onto the base of the flush valve assembly, ensuring it sits snugly and evenly in the groove.
- Reinstall Flush Valve: Place the flush valve assembly back into its position in the toilet tank, ensuring it is properly seated and secured.
- Restore Water Supply: Turn the water shut-off valve counter-clockwise to restore the water supply to the toilet tank. Allow the tank to fill.
- Test Flush: Once the tank is full, perform a test flush to check for leaks and proper flushing action. Observe the base of the tank and the flush valve for any signs of water leakage.

6. Operating
After successful installation, your Glacier Bay 83SGB dual flush toilet should operate as intended, providing efficient and effective flushing. The new seal ensures a proper water tight closure, preventing leaks and maintaining consistent water pressure for both light and heavy flush options.
- Light Flush: Typically achieved by pressing the smaller button or a partial press of the lever, this uses less water for liquid waste.
- Full Flush: Activated by pressing the larger button or a full press of the lever, this uses more water for solid waste.
The new seal restores the original factory performance, ensuring that the correct amount of water is held in the tank and released during each flush cycle.
7. Maintenance
The dual flush toilet seals are made from durable rubber material designed for longevity. To ensure continued optimal performance:
- Avoid Harsh Chemicals: Do not use harsh chemical cleaners in the toilet tank, as these can degrade rubber components over time.
- Regular Inspection: Periodically inspect the seal for any signs of wear, cracking, or deformation. If you notice any issues, consider replacing the seal to prevent future leaks.
- Cleanliness: Keep the area around the flush valve and seal free from mineral buildup or debris, which can interfere with proper sealing.
8. Troubleshooting
If you encounter issues after replacing the seal, refer to the following troubleshooting guide:
| Problem | Possible Cause | Solution |
|---|---|---|
| Toilet still leaks from tank to bowl | Seal not seated correctly; incorrect seal size; flush valve assembly not properly reinstalled. | Turn off water, drain tank, and re-inspect the seal's position. Ensure it is flat and fully seated. Verify that the flush valve assembly is securely in place. Confirm the seal is the correct size for your Glacier Bay 83SGB model. |
| Weak or incomplete flush | Water level in tank is too low; obstruction in flush valve. | Check the water level in the tank; it should be at the fill line. Inspect the flush valve for any debris that might be impeding its movement. |
| Toilet runs intermittently | Minor leak from seal; fill valve issue. | Ensure the seal is perfectly clean and seated. If the issue persists, the fill valve might need adjustment or replacement. |
