Assemble the P-trap and connect it to the bottom of the T-fitting. To connect the P-trap to the PVC drain stub-out in the wall, glue a threaded adapter onto the stub-out using PVC pipe cement. Apply the cement to both the outside of the pipe and the inside of the adapter, then push and twist them together for a strong bond. Once the adapter is set, connect the P-trap using the final slip nut and washer.

FAQs
Is 4 hours a realistic time estimate for a beginner, or should I allocate more time for this project?
The 4-hour estimate is a good average for someone with basic DIY skills. However, beginners should budget an extra 1-2 hours, especially for dealing with corroded old components or unexpected issues. Rushing the leak test is a common mistake, so take your time and don't feel pressured by the estimate.
What's the most common mistake beginners make that leads to leaks, and how can I prevent it?
The most common mistake is improper sealing or overtightening/undertightening connections. Ensure you apply plumber's putty correctly around the drain flange and hand-tighten all plastic connections. For metal components, hand-tighten and then only a quarter turn more with pliers to avoid stripping threads or cracking pipes.
The guide mentions plumber's putty for the drain flange; can I use silicone sealant instead for a better seal?
While silicone sealant can be used for the drain flange, plumber's putty is often preferred for its ease of use, pliability, and easy removal if adjustments are needed. If you choose silicone, use a kitchen/bath-grade product and allow adequate curing time before running water to test for leaks, as it's harder to adjust once set.
Beyond the listed tools, are there any other essential items or safety gear I should have on hand for this plumbing project?
Yes, always have a bucket or old towels ready to catch residual water during old drain removal. Safety glasses are recommended, especially when cutting pipes or dealing with potential splashes. Gloves can also protect your hands from grime and chemicals, making the job more comfortable and clean.
