How to Remove a Garbage Disposal and Install a Standard Sink Drain · Step 6 of 9
In this video
Take a generous amount of plumber's putty and roll it into a rope about a half-inch thick. Wrap this putty rope around the underside of the new sink flange. Press the flange firmly into the sink drain opening. From under the sink, slide the fiber gasket on, followed by the backup flange and the mounting ring. Hold these in place while you install the snap ring into the groove on the sink flange to hold the assembly together. Finally, use a screwdriver to tighten the three mounting screws evenly and firmly, which will pull the assembly tight against the sink and create a watertight seal.
Goal: Install New Sink Flange and Mounting Hardware
- Tighten the three screws in an alternating pattern to ensure even pressure and a good seal.

FAQs
Is this project truly beginner-friendly, and how much time should I realistically set aside?
Yes, it is designed for beginners. While the steps are straightforward, you should allocate the full estimated 6 hours. This allows ample time for prep, unexpected issues, and thorough leak testing, which is crucial for a successful outcome.
What are the most critical safety precautions I need to take before starting this project?
Your top priority is safety: immediately turn off the electrical power to the disposal at your circuit breaker and shut off the hot and cold water supply valves under the sink. Always wear safety gloves to protect your hands from sharp edges, old grime, and potential chemical exposure during cleaning.
Do I really need all the specialized tools listed, like the basket strainer wrench, or can I get by with standard tools?
While basic tools are essential, a basket strainer wrench (e.g., Husky 16PL0141) is highly recommended. It significantly simplifies removing the old and installing the new sink strainer, ensuring a tighter seal and preventing damage that can occur with improvised tools.
What's the most common problem people encounter when switching from a disposal to a standard drain, and how can I avoid it?
The most common issue is leaks, especially around the new sink strainer and drain pipe connections. To avoid this, apply a generous, continuous bead of plumber's putty (like Oatey 311662) under the new strainer flange and ensure all new drain connections are snug, using slip-joint pliers without overtightening.
