How to Attach a Bathroom Sink Drain

Attaching a bathroom sink drain is a relatively simple plumbing task that can be completed in a few steps. However, it is important to follow the instructions carefully to avoid any leaks or damage to your sink.

Materials You Will Need:

Pop-up drain assembly
Washer
Pliers
Putty knife or scraper
Plumber's putty

Step-by-Step Instructions:

1. Remove the old drain: If there is an existing drain, start by removing it. Use pliers to loosen the slip nut that holds the drain in place. Once the slip nut is loose, pull the drain out of the sink.

2. Clean the drain hole: Once the old drain is removed, use a putty knife or scraper to clean the drain hole. Remove any old putty or sealant.

3. Apply plumber's putty: Roll out a small piece of plumber's putty into a snake-like shape. Place the putty around the drain hole, forming a seal between the drain and the sink.

4. Place the washer: Place the washer over the drain hole, on top of the plumber's putty.

5. Attach the pop-up drain assembly: Insert the pop-up drain assembly into the drain hole. The assembly should fit snugly into the hole.

6. Tighten the slip nut: Use pliers to tighten the slip nut that holds the drain assembly in place. Be sure to tighten the nut securely, but do not overtighten it.

7. Test the drain: Run water into the sink to test the drain. Make sure that there are no leaks around the drain.

Tips:

If you are unsure about any of the steps, consult with a qualified plumber.
Use a flashlight to help you see inside the drain hole when cleaning it.
Apply a thin layer of petroleum jelly to the rubber seal of the drain assembly to prevent it from sticking.
If the drain is still leaking after tightening the slip nut, you may need to add more plumber's putty to the seal.

Conclusion:

Attaching a bathroom sink drain is a straightforward task that can be completed with minimal tools and materials. By following the steps outlined above, you can ensure a leak-proof seal and a functional drain for your bathroom sink.
