How to Install a Bathroom Sink Drain

Replacing a bathroom sink drain is a relatively easy plumbing project that can be completed in about an hour. The following instructions will guide you through the process step by step.

Tools and Materials You'll Need:

Adjustable wrench
Plumber's putty
New sink drain
Bucket
Rags

Step-by-Step Instructions:

1. Turn off the water supply. Locate the shut-off valves under the sink and turn them clockwise to close them. Open the faucet to release any remaining water in the lines.

2. Remove the old drain. Place a bucket under the drain to catch any water that may leak out. Use an adjustable wrench to loosen the locknut that holds the drain in place. Once the locknut is loose, you can unscrew the drain by hand.

3. Clean the drain hole. Use a rag to clean any debris or old plumber's putty from the drain hole. This will help ensure a good seal for the new drain.

4. Apply plumber's putty. Roll a small piece of plumber's putty into a rope and shape it into a ring that fits around the base of the new drain.

5. Install the new drain. Insert the new drain into the drain hole and press down firmly. Tighten the locknut by hand, then use the adjustable wrench to fully tighten it.

6. Turn on the water supply. Slowly open the shut-off valves under the sink. Check for leaks around the drain. If you see any leaks, tighten the locknut further.

7. Finish the installation. Place the stopper in the drain and press down firmly to create a seal. Run water into the sink and check for any leaks around the drain or stopper.

Tips:

If you're replacing a drain with a different size or shape, you may need to purchase an adapter.
If you're having trouble tightening the locknut, you can use a pair of pliers to grip it.
Once the drain is installed, it's a good idea to test it regularly for leaks.

Conclusion:

Replacing a bathroom sink drain is a straightforward task that can be completed with a few simple tools and materials. By following the instructions above, you can easily update your bathroom sink and keep your plumbing in good working order.
