4. Setup and Installation
This section provides general guidance for installing the basin waste. Specific basin designs may require slight variations.
- Prepare the Basin: Ensure the basin's waste hole is clean and free from debris.
- Apply Sealant: Apply a bead of plumber's putty or silicone sealant around the underside of the waste flange (the top part that sits inside the basin). This helps create a watertight seal.
- Insert Waste Unit: Insert the waste unit through the basin hole from the top. Ensure the flange is centered and seated correctly.
- Secure from Below: From underneath the basin, slide the rubber washer, then the plastic washer, and finally the metal back nut onto the threaded body of the waste.
- Tighten: Hand-tighten the metal back nut, then use a suitable wrench to gently tighten it further. Do not overtighten, as this can damage the basin or the waste unit.
- Connect to Trap: Connect the waste unit to your basin trap (not included) according to the trap manufacturer's instructions. Ensure all connections are secure and watertight.
- Test for Leaks: Turn on the water supply and fill the basin. Check thoroughly for any leaks around the waste unit and trap connections. Tighten connections as necessary.

5. Operating Instructions
The Bristan Round Push Basin Waste features a simple push-button mechanism for operation:
- To Close the Waste: Gently press the center of the waste plug. It will click into the closed position, retaining water in the basin.
- To Open the Waste: Gently press the center of the waste plug again. It will click into the open position, allowing water to drain from the basin.
6. Maintenance
Regular cleaning and maintenance will ensure the longevity and optimal performance of your basin waste.
- Cleaning: Clean the chrome finish regularly with a soft cloth and mild soapy water. Avoid abrasive cleaners, scouring pads, or chemical agents, as these can damage the finish.
- Removing Debris: Periodically, the top part of the waste can be unscrewed to remove accumulated hair and debris. This helps prevent blockages and maintains efficient drainage.
- Check Seals: Occasionally inspect the seals for any signs of wear or damage. Replace if necessary to prevent leaks.
7. Troubleshooting
If you encounter issues with your basin waste, refer to the following common solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Water leaking around the waste flange | Improperly seated sealant or loose back nut. | Ensure sealant is correctly applied. Gently tighten the back nut. If leaks persist, remove, reapply sealant, and reinstall. |
| Slow drainage or blockage | Accumulation of hair and debris in the waste unit or trap. | Unscrew the top of the waste plug and remove any debris. Clean the trap if necessary. |
| Push mechanism not engaging | Debris interfering with the mechanism or internal component issue. | Remove the top part and clean the mechanism. If the issue persists, contact customer support. |
