Connect Drain Pipes (P-Trap) — Assemble the New Drain Pipes
Part of project
How to Remove a Garbage Disposal and Install a Standard Sink Drain · Step 7 of 9
In this video
Assemble the drain plumbing under the sink. First, attach the tailpiece to the threads on the bottom of the drain strainer, making sure the tailpiece washer is seated correctly inside the nut. Hand-tighten this connection. Next, assemble the P-trap by connecting the J-bend to the tailpiece and the trap arm to the drain pipe in the wall. These connections use slip-joint nuts and beveled washers. Ensure the beveled side of the washer faces the direction it needs to seal against. Hand-tighten all the nuts securely.
Goal: Plumbing Pipes Repair
- Before assembling, check the cut ends of the plastic pipes for any burrs. Scrape them off with a utility knife to prevent hair and debris from getting caught, which can lead to future clogs.

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.
