Installation Instructions
This section outlines the general steps for installing the Kohler disposal flange. Refer to your garbage disposal unit's specific instructions for detailed guidance, as procedures may vary.
1. Prepare the Sink Opening
- Turn off the power to the garbage disposal at the circuit breaker.
- If replacing an existing flange, remove the old flange and clean the sink opening thoroughly. Remove any old plumber's putty or sealant.
- Ensure the sink opening is dry and free of debris.
2. Apply Plumber's Putty
Roll a bead of plumber's putty (approximately ½ inch thick) and apply it around the underside of the Kohler disposal flange rim. Ensure a continuous seal.

3. Position the Flange
- Insert the flange into the sink opening from above, pressing down firmly to create a seal with the putty.
- From underneath the sink, attach the fiber gasket, backup flange, and mounting ring to the disposal flange.
- Tighten the screws on the mounting ring evenly until the flange is secure and excess putty squeezes out from around the rim. Wipe away any excess putty.
4. Connect the Garbage Disposal
Follow the manufacturer's instructions for your specific garbage disposal unit to attach it to the newly installed disposal flange. Ensure all connections are tight and leak-free.
5. Test for Leaks
- Once the disposal is connected, turn on the water and fill the sink. Check for any leaks around the flange and disposal connections.
- If leaks are present, tighten connections as needed.
- Restore power to the garbage disposal unit.
Operating Instructions
The Kohler 11352-2MB Disposal Flange includes a stopper for convenient use:
- To stop water: Insert the stopper firmly into the flange opening. This will create a seal, allowing the sink to fill with water.
- To drain water: Remove the stopper from the flange opening.
- For disposal use: The stopper can be partially inserted or removed to allow food waste into the disposal while preventing splashing.
Maintenance and Care
- Cleaning: Clean the disposal flange and stopper regularly with a soft cloth and mild soap and water. Avoid abrasive cleaners, scouring pads, or harsh chemicals, as these can damage the finish.
- Finish Protection: The Vibrant Brushed Moderne Brass finish is durable, but prolonged exposure to acidic foods or harsh cleaning agents can affect its appearance. Rinse thoroughly after contact with such substances.
- Stopper Seal: Periodically check the rubber seal on the stopper for wear or damage. Replace if necessary to maintain a watertight seal.
Troubleshooting
- Leakage around flange:
- Ensure mounting screws are tightened evenly.
- Check if plumber's putty was applied correctly and created a complete seal. Reapply if necessary.
- Inspect gaskets for damage or improper seating.
- Stopper not holding water:
- Ensure the stopper is fully seated in the flange opening.
- Check the rubber seal on the stopper for debris or damage. Clean or replace the seal if worn.
- Discoloration of finish:
- Clean with mild soap and water. Avoid harsh chemicals.
- Ensure proper ventilation in the kitchen to prevent moisture buildup.
