- Screwdriver (flathead or Phillips, depending on disposal model)
- Adjustable wrench or pliers
- Bucket and towels (for catching water)
- Safety glasses and gloves
Installation Steps:
- Prepare the Sink Opening: Ensure the sink opening is clean and free of any old sealant or debris. If replacing an existing flange, remove it completely.
- Apply Sealant: Roll a bead of plumber's putty or apply silicone sealant around the underside of the flange rim.
- Insert Flange: From the top of the sink, insert the flange into the sink opening, pressing firmly to create a seal.
- Assemble Underneath: From underneath the sink, slide the rubber gasket, then the fiber gasket, and finally the mounting ring onto the flange shank.
- Secure Mounting Ring: Thread the large locknut onto the flange shank and tighten it by hand.
- Connect Disposal Unit: Align the garbage disposal unit with the flange and secure it according to the disposal manufacturer's instructions. This typically involves tightening mounting screws or a twist-lock mechanism.
- Check for Leaks: Once the disposal is securely attached, turn on the water briefly and check for any leaks around the flange and disposal connection. Tighten connections as necessary.

5. Maintenance
Regular maintenance will help preserve the appearance and functionality of your BLANCO Disposal Flange.
Cleaning:
- Clean the stainless steel surface regularly with a soft cloth and mild soap or a non-abrasive stainless steel cleaner.

- Rinse thoroughly with clean water and dry with a soft cloth to prevent water spots.
Inspection:
- Periodically check the flange and disposal connection for any signs of leaks or loose fittings.
- If a leak is detected, turn off the power to the disposal and tighten the connections or reapply sealant as needed.
6. Troubleshooting
This section addresses common issues you might encounter with your disposal flange.
| Problem | Possible Cause | Solution |
|---|---|---|
| Water leaking around the flange. | Improperly sealed flange or loose mounting ring. | Turn off power to disposal. Tighten the locknut underneath the sink. If leaking persists, remove the flange, clean the area, reapply plumber's putty or silicone sealant, and reinstall. |
| Flange appears loose in the sink opening. | Mounting ring not sufficiently tightened. | Turn off power to disposal. From underneath the sink, ensure the rubber and fiber gaskets are correctly positioned, then tighten the large locknut firmly. |
| Poor drainage through the flange. | Obstruction in the disposal or drain pipe. | This is typically a disposal or drain issue, not the flange itself. Refer to your garbage disposal's manual for troubleshooting clogs. |
