How To Install A Kitchen Sink Drain

The steps:

  1. Measure the Sink’s Drain Hole

The measurement of the sink's drain hole is required in order to acquire the correct size sink drain kit.

Yes, all of the pieces you'll need to install a new kitchen drain are now packaged together, though you may still buy them separately.

A rubber-seal washer, a fastening nut, a basket strainer, a friction-protection band, and a tailpiece that links the drainpipe and the kitchen sink drain make up the sink drain kit.

It's also a good idea to make sure the tailpiece fits the size of your drainpipe. We recommend choosing a sink drain system with a metal tailpiece over a plastic one because it is more sturdy.

  1. Remove the Old Strainer

To remove the drainpipe from the drain's tailpiece, unscrew the pipe connector using your pliers. 

With a basket wrench, unscrew the nuts that hold the strainer in place. Then, from the sink's underside, remove the basket strainer.

To avoid damaging any components, use the wrench or pliers with as little force as possible. You'll be able to disconnect the drainpipes in the sink cabinet after completing these steps.

  1. Apply Plumber’s Putty to the Basket Strainer

Roll a thin piece of plumber's putty in your palm and thread it all the way around the base of the strainer.

To avoid one portion of the strainer looking more padded than others, the rolled-up putty should have an identical width throughout its stretch.

  1. Insert the Basket Strainer into the Sink Drain Hole

Cut off excess putty if the thread appears too long after wrapping the roll of putty around the basket strainer.

Just enough to establish a strong seal from the putty between the hole on the drain and the basket strainer, press down the basket strainer into the hole for the sink drain. 

If you press too firmly on the strainer, the putty will be squeezed out completely instead of forming an even seal.

Crawl into the sink cabinet and wipe the putty off the basket strainer's underside.

  1. Slip the Friction Band and Rubber-Seal Washer over the Base of the Strainer

Place the washer on top of the strainer basket.

It also adds to the sealing effect. Then, to protect the washer from the nut, slide the friction band over it.

  1. Tighten the Nut to the Basket Strainer

To connect the nut to the threaded base of the basket strainer, turn it clockwise.

To establish a tighter seal, use your hand to drive it in as tightly as possible before using a basket wrench.

Hold the filter's base in place with needle-nose pliers while tightening the nut with a wrench.

 It will stop the basket strainer from rotating in lockstep with the wrench. While tightening the nut, clean up any extra putty.

  1. Connect the Brass Tailpiece and Basket Strainer

Screw the tailpiece into the basket strainer's thread. The tailpiece is threaded as well.

Align the threads on the basket strainer's base with the threads on the threads on the basket strainer's base and tighten it clockwise.

  1. Fix the Brass Tailpiece with the Drainpipe

In the drainpipe, place a rubber gasket. When you attach the drainpipe to the tailpiece, the gasket maintains a watertight seal. 

Align the drainpipe's top with the tailpiece's bottom with care. Connect the drainpipe to the threaded brass tailpiece base with the connector ring.

  1. Use a Wrench to Tighten the Connector Ring

To ensure a tighter seal, tighten the ring as much as you can with your hand before using a wrench.

 To avoid shattering the plastic ring or the drainpipe, you should only use appropriate force when using the wrench.

  1. Turn on the Faucet to Test the System for Leaks

Turn on the kitchen faucet after turning on the shut-off valves.

Allow the water to drain for a reasonable amount of time while you inspect the system for any leaks.

If you observe any leakage, you must use a wrench to tighten the leaking portion.

You should, proceed with caution. It's all too usual at this point to use more force than is necessary and damage a delicate component.


Double kitchen sinks provide your kitchen more space and a more attractive appearance. Double kitchen sinks may be installed by any homeowner with the correct equipment, resources, and time, whether they are installing one for the first time in a new home or remodeling an older home to replace the existing sink with something new. Even though two sink pieces are used instead of one, the installation process and operation of the sink is identical to that of a single sink.

Now, we going to move forward to how do you plumb a double kitchen sink?

Step 1.

Make a list of the pieces in the kit and familiarize yourself with them. After each component of the "J" (also known as an exhaust pipe) has been joined to the bottom of their respective drains at the bottom of the sink, it attaches to the knuckle "T" portion. It is situated between the two drain holes (drain baskets).

To remove sewage water, the sink siphon is a U-shaped piece that connects to the wall drain pipe (a straight pipe that sticks out of the back of your closet wall) as well as the "T" portion.

Step 2.

Before tightening the circular slide nuts that are attached to each piece on the threads and attaching the plastic parts, dry assemble your installation. To begin, connect the straight segment of PVC pipe to the wall drain pipe and then attach the sink trap (long, U-shaped piece) to the "T" connection. The trap and knuckle should be centered front to back and side to side under the two drain baskets, directly under the sink.

Step 3.

Cut the excess pipe with a hacksaw. To hold the threads of each piece in place while making modifications, loosely link them with a nut. Check to see if any surplus sections of the exhaust pipe need to be cut off after you've dry-installed the drainpipe, sink siphon, and knuckle. Cut the tails to fit by hacksawing the long ends, then drying them to fit the sink baskets and "T" joint.

Step 4.

To keep the installation together, tighten all of the skid nuts. Tighten the nuts in place using a pair of Channellock pliers. Convert them into a rightward movement. If you twist them too much, the pipes will shatter. Apply enough pressure to ensure a snug fit. Before using the sink, run the water through the pipes and check for leaks.


Normally, you do not need a Professional plumber for a double sink installation. Using tee fittings, special valves, extension pipes, and hoses, you can easily adapt the supply and drain pipes to suit two sinks. Depending on your local plumbing codes, you may have to vent each sink independently.


Most people questioned about does a double sink vanity share the same drain for both sinks? And does it need two traps below the sinks?


Well, a double sink vanity has two sinks. Each sink will require its own drainage system. However, two sinks do not require their own p-traps. They usually share one trap. Of course, you can have two if that's what works best for your application, but you'll be wasting money you don't need to.
