How to Install a Bathroom Sink Drain and P-Trap · Step 3 of 6
In this video
Slide the pivot rod back into the drain body, ensuring the gaskets are in place. Make sure the end of the rod engages the new stopper in the orientation you chose. Thread the retaining nut back on clockwise and hand-tighten it until it's snug. You can adjust the tightness to control the friction of the stopper's movement.
Goal: Secure the new stopper
- Do not overtighten the pivot rod nut, as this can make the stopper mechanism stiff or damage the plastic threads.

FAQs
Is this 'beginner' difficulty truly accurate, and can I realistically complete it in 3 hours if I'm new to plumbing?
Yes, this project is considered beginner-friendly as it doesn't require complex pipe cutting or soldering. The 3-hour estimate is achievable for most DIYers, but gathering all tools and materials beforehand and reviewing the steps thoroughly will help minimize delays. If your existing drain components are heavily corroded, removal might extend the overall time slightly.
What's the most common reason for leaks after installing a new drain and P-trap, and how can I prevent them?
The most common cause of leaks is insufficiently tightened connections or improperly sealed joints. Ensure all slip nuts are hand-tightened firmly, then give them an extra quarter to half-turn with channel lock pliers, being careful not to overtighten and crack plastic components. Always apply a consistent, generous bead of plumber's putty under the drain flange to create a watertight seal against the sink basin.
The guide mentions plumber's putty; can I use silicone sealant instead for the drain flange?
While silicone sealant can provide a durable seal, plumber's putty is often preferred for drain flanges because it remains pliable, making future disassembly much easier if needed. If you choose silicone, ensure it's 100% silicone specifically rated for bathroom/kitchen use and allow adequate curing time before running water. Plumber's putty typically offers an immediate, reliable seal.
What should I do if the old drain assembly is seized or difficult to remove from the sink?
Old drains can be stubborn due to corrosion or mineral buildup. First, try applying penetrating oil to the threads of the locknut under the sink and let it sit for a few minutes. Use your channel lock pliers for maximum leverage, turning slowly but firmly. If it's completely stuck, you may need to carefully cut the old drain pipe components below the sink with a mini hacksaw to free the drain body, being careful not to damage the sink itself.
