A properly installed kitchen sink drain ensures efficient drainage and prevents leaks, making your kitchen a more functional and pleasant space. In this guide, we will walk you through the process of installing a kitchen sink drain, covering everything from necessary tools to the final touches.

Tools and Materials:

Before you start the installation, gather the following tools and materials:

  1. Plumber’s putty
  2. Plunger
  3. Pipe wrench
  4. Adjustable pliers
  5. Teflon tape
  6. Pipe cutter
  7. Screwdriver
  8. Bucket
  9. Hacksaw
  10. Pipe fittings (P-trap, tailpiece, trap arm)
  11. Compression fittings
  12. Slip-joint pliers

Step 1: Clear the Area:

Before beginning the installation, clear out the space under the sink. Remove any items stored there, as you’ll need easy access to the plumbing.

Step 2: Turn off Water Supply:

Locate the shut-off valves under the sink and turn off the hot and cold water supply.

Step 3: Disconnect Existing Plumbing:

Use a pipe wrench or adjustable pliers to disconnect the existing plumbing. Remove the nuts and washers connecting the old drain pipes.

Step 4: Remove Old Drain:

Detach the old drain by loosening the slip nut connecting it to the sink strainer. If there’s plumber’s putty sealing the strainer, gently pry it away.

Step 5: Clean the Sink Opening:

Scrape off any old plumber’s putty or debris from the sink opening. A putty knife or scraper can be useful for this step.

Step 6: Apply Plumber’s Putty:

Roll a small amount of plumber’s putty into a rope and apply it around the underside of the new sink strainer. Press the strainer into the sink opening, ensuring a tight seal.

Step 7: Install the Basket Strainer:

Thread the slip nut onto the basket strainer from underneath the sink. Tighten it with pliers to secure the strainer in place.

Step 8: Attach the Tailpiece:

Connect the tailpiece to the bottom of the basket strainer using a slip nut. Use pliers to tighten the nut securely.

Step 9: Install the P-Trap:

Attach the P-trap to the tailpiece and the wall drain pipe. Make sure the trap arm is angled downward slightly for proper drainage.

Step 10: Check for Leaks:

Turn on the water supply and check for leaks. If you notice any leaks, tighten the connections as needed.

Step 11: Secure the Pipes:

Use pipe hangers or straps to secure the drain pipes to the wall or cabinet. This prevents sagging and ensures proper drainage.


By following this step-by-step guide, you can successfully install a kitchen sink drain and enjoy a leak-free and efficiently draining sink. Remember to take your time, double-check your connections, and enjoy the satisfaction of a DIY project well done.
