How To Install A Kitchen Sink Drain Pipe

Installing a kitchen sink drain pipe is a relatively simple task that can be completed in a few hours. By following these step-by-step instructions, you can save yourself the cost of hiring a plumber.

Materials you will need:

New kitchen sink drain pipe

Adjustable wrench

Plumber's putty

Knife or utility knife

Bucket

Rags

Step 1: Remove the old drain pipe.

Place a bucket under the old drain pipe to catch any water that may leak out. Use an adjustable wrench to loosen the nuts that hold the drain pipe in place. Once the nuts are loose, remove the old drain pipe by pulling it straight down.

Step 2: Clean the drain hole.

Use a knife or utility knife to remove any old plumber's putty from the drain hole. Wipe the drain hole clean with a rag.

Step 3: Apply plumber's putty to the new drain pipe.

Roll out a small piece of plumber's putty into a rope. Apply the plumber's putty to the bottom of the new drain pipe, around the outside edge. The plumber's putty will help to seal the drain pipe and prevent leaks.

Step 4: Insert the new drain pipe into the drain hole.

Insert the new drain pipe into the drain hole. Align the drain pipe so that the nuts are facing up. Tighten the nuts until the drain pipe is secure. Do not overtighten the nuts, as this could damage the drain pipe.

Step 5: Connect the drain pipe to the P-trap.

The P-trap is the U-shaped pipe that is connected to the drain pipe. Use an adjustable wrench to loosen the nuts that hold the P-trap in place. Insert the drain pipe into the P-trap. Tighten the nuts until the drain pipe is secure.

Step 6: Connect the P-trap to the drain line.

The drain line is the pipe that runs from the P-trap to the main sewer line. Use an adjustable wrench to loosen the nuts that hold the P-trap to the drain line. Insert the P-trap into the drain line. Tighten the nuts until the P-trap is secure.

Step 7: Test the drain.

Run water into the sink and check for leaks. If there are no leaks, the drain pipe is installed correctly.
