Armed with the right tools and a systematic approach, you'll soon have a leak-free sink with optimal drainage. Let's delve into the specifics to ensure your kitchen transformation is a success.

Tools and Materials:

Before diving in, gather these essential 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: Set the Scene:

Prepare your workspace by clearing out the area under the sink. Remove stored items for easy access to the plumbing.

Step 2: Halt the Water Supply:

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

Step 3: Disconnect Existing Plumbing:

Use a pipe wrench or adjustable pliers to disconnect the existing plumbing. Loosen nuts and washers that connect the old drain pipes.

Step 4: Bid Farewell to the Old Drain:

Say goodbye to the old drain by loosening the slip nut that connects it to the sink strainer. Remove any remnants of old plumber's putty.

Step 5: Clean the Sink Opening:

Ensure a clean surface by eliminating any residual plumber's putty or debris from the sink opening, using a putty knife or scraper.

Step 6: Craft a Plumber's Putty Seal:

Create a small rope of plumber's putty and apply it around the underside of the new sink strainer. Press the strainer into the sink opening to create a secure seal.

Step 7: Embrace the Basket Strainer:

Thread the slip nut onto the basket strainer from beneath the sink. Use pliers to tighten it, securing the strainer firmly in place.

Step 8: Connect the Tailpiece:

Join the tailpiece to the bottom of the basket strainer using a slip nut. Use pliers to achieve a snug and secure connection.

Step 9: Assemble the P-Trap:

Link the P-trap to the tailpiece and the wall drain pipe, ensuring the trap arm has a slight downward angle for optimal drainage.

Step 10: Leak Inspection:

Switch on the water supply and inspect thoroughly for leaks. If any appear, tighten the connections accordingly.

Step 11: Secure the Pipes:

Use pipe hangers or straps to fasten the drain pipes to the wall or cabinet, preventing sagging and ensuring effective drainage.


With this detailed guide at your disposal, take your time, follow each step diligently, and relish the satisfaction of a successful kitchen sink drain installation.
