Remove Old Sink Strainer — Preparation and Removal of Old Drain

How to Install a Bathroom Sink Drain and P-Trap · Step 1 of 7
In this video
First, place a bucket or pan under the P-trap to catch any residual water. Loosen the slip nut connecting the tailpiece to the P-trap. Next, remove the large retaining nut that holds the strainer to the sink. If it's corroded, it may break off, or you may need to use pliers or even a chisel. Since you are replacing the entire unit, damaging the old strainer is acceptable. Once the nut is off, push the entire old strainer assembly up through the top of the sink and remove it.
Goal: Remove Old Sink Strainer
- Place a bucket and a cookie sheet or pan underneath the work area to catch any water or debris that falls during disassembly.
- The old retaining nut may be heavily corroded and difficult to remove. It is acceptable to break it off since it is being replaced.

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.
