Hooking Up Kitchen Sink Drain

Installing or replacing a kitchen sink drain is a relatively simple plumbing project that can be completed in a few hours. Here's a step-by-step guide to help you get the job done right:

Tools and Materials You'll Need:

Adjustable wrench
Plumber's putty
Slip joint pliers
Basin wrench
New kitchen sink drain assembly
Bucket or bowl
Rags

Step-by-Step Instructions:

1. Shut Off the Water Supply:

Locate the shut-off valves under the sink and turn them clockwise to shut off the water supply to the sink.

2. Remove the Old Drain Assembly:

Place a bucket or bowl under the sink to catch any water that may leak out. Use an adjustable wrench to loosen the nuts that hold the old drain assembly in place. Once the nuts are loose, you can remove the old drain assembly.

3. Clean the Drain Hole:

Use a rag to clean the drain hole in the sink. Remove any old plumber's putty or debris that may be present.

4. Apply Plumber's Putty:

Roll a small piece of plumber's putty into a rope and place it around the base of the new drain assembly. The plumber's putty will help to create a watertight seal between the drain assembly and the sink.

5. Insert the New Drain Assembly:

Insert the new drain assembly into the drain hole and tighten the nuts that hold it in place. Be careful not to overtighten the nuts, as this could damage the sink.

6. Connect the P-Trap:

Connect the P-trap to the drain assembly. The P-trap is a U-shaped pipe that helps to prevent sewer gases from entering the sink. Tighten the nuts that hold the P-trap in place.

7. Connect the Garbage Disposal (Optional):

If you have a garbage disposal, connect it to the P-trap. Tighten the nuts that hold the garbage disposal in place.

8. Turn on the Water Supply:

Turn on the shut-off valves under the sink to restore the water supply to the sink. Check for any leaks around the drain assembly, P-trap, and garbage disposal. If you find any leaks, tighten the nuts that hold these components in place.

Congratulations! You have successfully hooked up your kitchen sink drain.
