Install Kitchen Sink Drain Plumbing

Installing a kitchen sink drain is a straightforward plumbing task that you can do yourself with a few tools and materials. Here are the steps involved:

Gather Your Tools and Materials

Before you start, gather the following tools and materials:

Adjustable wrench
Plumber's putty
Teflon tape
Slip-joint pliers
Putty knife
Drain flange
Strainer basket
Tailpiece
Trap
P-trap adapter (if needed)
Dishwasher drain hose (if needed)
Garbage disposal drain hose (if needed)

Prepare the Sink Drain

First, you need to prepare the sink drain by removing the old drain assembly. Use an adjustable wrench to loosen the nuts that hold the drain flange in place, then remove the flange and the strainer basket.

Apply Plumber's Putty

Next, apply a bead of plumber's putty to the underside of the new drain flange. The putty will help to create a watertight seal between the flange and the sink.

Install the Drain Flange

Position the drain flange over the sink drain hole and tighten the nuts to secure it. Make sure that the flange is level and that the putty is squeezed out evenly around the edges.

Install the Strainer Basket

Place the strainer basket inside the drain flange and secure it with the screws or nuts that came with the basket.

Install the Tailpiece

The tailpiece is the pipe that connects the drain flange to the trap. Screw the tailpiece onto the drain flange, using Teflon tape to create a watertight seal.

Install the Trap

The trap is the U-shaped pipe that prevents sewer gases from entering the kitchen. Connect the trap to the tailpiece, using a slip-joint nut to secure the connection. If your sink has a double bowl, you will need to install a P-trap adapter to connect the two traps.
