How to Install a Kitchen Sink Drain?

How to Install a Kitchen Sink Drain

Planning on saving a couple of dollars on plumbing work? Or perhaps you simply can’t find a plumber in time to install your old, corroded and leaking sink drain with a new one. Well, keep on reading to find an easy to follow guide on how to install a kitchen sink drain.

How to Install a Kitchen Sink Drain

Required Tools:

• Pliers 

• Basket Wrench

• Plumber’s putty

• Drain Assembly kit

Choosing a Drain Assembly Kit:

Before you start installing your sink’s drain, it is important that you get the right drain assembly kit. The kit will include the following items:

  • A basket strainer
  • Locking nut
  • Rubber washer
  • Friction ring
  • Strainer cup

A brass tail piece (any other material will corrode faster so make sure to opt for this specific one)

Here’s a few things to keep in mind while choosing your drain kit:

  • Choose the right sized basket strainer by measuring the drain hole. You’ll need to make some difficult unnecessary adjustments if you get one that is bigger or small than your drain hole. You could also use your existing basket strainer for reference to make the process even easier!
  • You can get your kit at any local hardware store or online!

Removing an existing basket strainer

You will obviously need to remove your old strainer in order to replace it with a new one. For this, you’ll need some pliers to separate the drainpipe from the tailpiece. Do this by turning the metal fittings on the pipe. Next, use a basket wrench to unscrew the nut on the basket strainer’s underside and simply pull out the strainer.

Also, be sure to disconnect the drain pipes from your existing sink drain carefully so as to not damage them as you’ll be using the same ones! You’ll need to turn off the water supply valves by twisting them counter clockwise and use pliers to spin the metal rings holding the drainpipes together counter clockwise to pull them apart.

Installing the Sink Drain

Once you’ve removed the old drain, you can finally install your brand new sink drain!

Here is how to do this:

  • Use some plumber’s putty and knead it for a bit to soften it a little. Then, shape it into a rope that is four or five inches long. 
  • Wrap the putty rope around the bottom of the basket strainer to check if it is long enough. Cut off any excess part.
  • Once you’ve got a perfect sized rope with an even diameter, press the plumber’s putty on the underside of the strainer around its lip. Don’t press too much as you might thin out the rope! 
  • Next, put your basket strainer over the hole in the drain and push it into place. Press it gently to make a watertight seal between the strainer and the drain hole! 
  • Some excess putty might collect around the bottom of the basket. Wipe it away with a clean cloth! 
  • Then, slide on the items mentioned below in the same order onto the underside of the basket:
  1. Black rubber washer
  2. White friction ring
  3. Strainer cup
  4. The nut (a large metal ring)

Use needle nose pliers to keep the underside of the strainer in place. Then, use a basket wrench to tighten the nut. Make sure to tighten the nut as much as you can or you’ll have a leaking drain problem!

Now that you’ve got your strainer in place, you need to connect it with the drainpipes. Here’s how to do this:

  • Take the brass tailpiece from your kit, attach it to the strainer’s bottom. Screw it on tightly using your hands. 
  • Next, place the rubber compression gasket inside the drain pipe. These gaskets are small and flexible and they help in creating a watertight seal. They come in different sizes so make sure to get one that fits your drain pipes diameter. 
  • Hold the top of the drainpipe and the bottom of the tailpiece together and align their edges. 
  • Then, slide up the connecter ring present on the drainpipe and screw it onto the tailpiece to hold them tightly together.
  • Use a wrench to further strengthen the connection between the brass tailpiece and the drainpipe to eliminate any future leakage risks. Remember to be careful while doing this like too much pressure can crack the plastic connector ring!
  • Now you have a fully functioning sink with a perfect fit new drain!

Be sure to test the drain by turning on the faucet and make sure that there are no leaks!

Hope this short guide on how to install a kitchen sink drain will help you to do it on your own.
