How to Remove a Garbage Disposal and Install a Standard Sink Drain · Step 4 of 7
In this video
To reinstall the mounting assembly, first apply a rope of plumber's putty around the underside of the new strainer flange, or use an upper sink flange seal. Insert the flange into the sink drain opening. From underneath the sink, place the lower sink flange seal and the flange mounting plate over the strainer flange. Position the mounting bracket against the plate and hold it up while you snap the mounting ring into the groove on the strainer flange. Evenly tighten the three screws on the bracket to secure the assembly. Scrape away any excess plumber's putty from inside the sink.

FAQs
What are the most important safety steps to take before starting this project, especially since it involves electricity and water?
Always shut off power to the disposal circuit at your electrical panel first. Then, turn off the hot and cold water supply valves located under the sink. Have a bucket and towels ready for any residual water that may be in the pipes.
The tool list seems comprehensive, but are there any additional tools that would make this beginner project easier or more efficient?
While the listed tools are sufficient, a headlamp can greatly improve visibility in the dark cabinet space under the sink. A basin wrench can also be helpful for removing stubborn or hard-to-reach nuts from the old disposal or existing drain, though pliers often suffice.
What are the most common pitfalls or mistakes beginners make when installing a new sink drain, and how can I ensure a leak-free installation?
The biggest mistake is inadequate sealing. Ensure you apply a generous, even bead of plumber's putty under the basket strainer flange for a watertight seal. Also, avoid overtightening PVC connections, as this can crack fittings; hand-tightening plus a quarter turn with pliers is usually sufficient.
Given that I'm a beginner, is the 4-hour estimated time realistic, or should I budget more time for unexpected issues?
While the project is beginner-friendly and 4 hours is a good estimate, budgeting extra time is wise, especially if dealing with older, stubborn plumbing connections or unexpected discoveries. Give yourself 5-6 hours to work without rush, allowing for potential trips to the hardware store if needed.
