How To Hook Up A Bathroom Sink Drain

Replacing a bathroom sink drain is a relatively simple plumbing repair that can be completed in a few hours with the right tools and materials. Here are the essential steps involved in hooking up a bathroom sink drain:

Tools and materials you'll need:

Adjustable wrench
Plumber's putty
New sink drain assembly
Teflon tape

Step 1: Remove the old drain assembly

Place a bucket under the sink to catch any water that may leak out. Use an adjustable wrench to loosen the slip nut that holds the drain assembly in place. Once the slip nut is loose, you can remove the old drain assembly by pulling it straight up.

Step 2: Apply plumber's putty to the new drain assembly

Roll out a small piece of plumber's putty into a rope about 1/4 inch thick. Place the plumber's putty around the base of the new drain assembly, making sure to create a seal between the drain assembly and the sink.

Step 3: Install the new drain assembly

Insert the new drain assembly into the drain hole in the sink. Tighten the slip nut by hand until it is snug. Use an adjustable wrench to further tighten the slip nut, but be careful not to overtighten.

Step 4: Install the pop-up drain stopper

If your new drain assembly includes a pop-up drain stopper, insert the stopper into the drain assembly from below. Push up on the stopper to engage the spring mechanism.

Step 5: Install the lift rod

If your new drain assembly includes a lift rod, insert the rod into the hole in the stopper. Attach the other end of the lift rod to the pop-up drain lever on the sink.

Step 6: Wrap the drainpipe with Teflon tape

Apply a few wraps of Teflon tape to the threads of the drainpipe. This will help to create a watertight seal.

Step 7: Connect the drainpipe to the drain assembly

Hand-tighten the drainpipe to the drain assembly. Use an adjustable wrench to further tighten the connection, but be careful not to overtighten.

Step 8: Test the drain

Turn on the water and check for any leaks around the drain assembly. If there are no leaks, your new drain is installed correctly.

Hooking up a bathroom sink drain is a relatively simple plumbing repair that can be completed in a few hours with the right tools and materials. By following these steps, you can save yourself the expense of hiring a plumber.
