How to Remove a Garbage Disposal and Install a Standard Sink Drain · Step 6 of 7
In this video
Perform the final assembly. Slide the nuts and gaskets onto the pipes in the correct order. Connect the vertical tailpiece to the sink drain. Attach the bottle trap body. Insert the horizontal arm into the bottle trap and the wall plug. Hand-tighten all connections. Once everything is assembled, use a level to confirm the horizontal arm is still level. Screw the pop-up drain cap into place. Finally, turn on the faucet, fill the sink basin partially, and then release the pop-up stopper to test the entire system for leaks. Carefully check every joint and connection for drips.
Goal: Complete the installation and verify it is leak-free

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.
