How to Install a Sink Strainer: A Step-by-Step Guide

A sink strainer is an incredibly useful tool to have in any kitchen or bathroom. It prevents clogging by trapping food particles, hair, and other debris from entering your plumbing system. Installing a sink strainer is a simple process that can be done by anyone with basic DIY skills.

If you’re tired of dealing with slow drainage and unpleasant odors in your sink, it’s time to install a sink strainer. In this step-by-step guide, we will walk you through the process of installing a sink strainer, from the tools you need to the final tightening of the locknut. With this knowledge, you’ll be able to complete the installation in no time, and enjoy a clog-free sink for years to come.

Quick Answer
To install a sink strainer, first remove any old strainer and clean the sink thoroughly. Insert the new strainer into the sink hole and secure it in place using the provided gasket and locking nut. Tighten the nut with pliers and wipe away any excess putty. Finally, attach the tailpiece and trap to the bottom of the strainer and tighten the connections with a wrench. Test the strainer by running water to ensure a proper seal.

Gather the Necessary Tools and Materials

Before you begin to install a sink strainer, it is important to gather all the necessary tools and materials for the task. Installing a sink strainer is not a complicated process, but without the required tools and materials, the process may turn out to be frustrating.

The materials you need for installing a sink strainer include the sink strainer itself, plumber’s putty, and a roll of Teflon tape. You will also need a wrench, a screwdriver, and a pair of pliers. Make sure that you have all the necessary tools and materials nearby before you start the installation process so that you do not have to go looking for them in the middle of the installation.

Remove the Old Sink Strainer

Removing the old sink strainer is an essential part of the installation process. It is crucial to do this step carefully to avoid damaging the sink or the pipes. Firstly, turn off the water supply valves to the sink and place a bucket under the sink to collect any water that may spill out. Next, use a wrench to loosen the locknut holding the old strainer in place. Turning the nut counterclockwise should do the trick. If the nut is hard to turn, try using a penetrating oil to loosen it up.

Once the locknut is removed, the old strainer should come out easily. Take out the old gasket and clean any debris or old putty around the sink hole. The sink strainer is now removed, and you can move on to installing the new one. It is essential to replace the old strainer as it can affect the sink’s water flow and cause clogs. With these simple steps, you can replace your sink strainer and ensure hassle-free dishwashing and cleaning in your kitchen.

Clean the Sink Drain and Flange

Before you start installing the sink strainer, it is crucial to clean the sink drain and flange thoroughly. The objective is to remove all debris, dirt, grime, or any other material that may have accumulated in the drain, flange, or threaded area. This will ensure a tight and leak-free seal after installing the sink strainer. To do this, run hot water through the sink drain to soften any oily or greasy clogs, and then use a plumber’s snake to break up any stubborn debris. Once done washing, wipe the drain and flange with a clean cloth.

Be sure to examine the flange and drain area closely to ensure it is free from any residue. Get rid of any large objects that may obstruct the sink strainer’s connection to the drain. The cleaner the sink drain and flange are, the easier installing the sink strainer will be. Cleaning the drain and flange carefully also ensures that the sink strainer remains stable and looks aesthetically pleasing after installation. Make sure that you dry every part of the drain and flange with a rag or towel and take the drain insert out to make sure you clean the fixed surface beneath it.

Apply the Plumbers Putty

Applying the plumbers putty is an essential step in installing a sink strainer. The putty creates a watertight seal around the base of the sink strainer which helps prevent any leaks from occurring. The putty is a clay-like substance that is easy to mold and manipulate.

To apply the plumbers putty, first, take a small amount of putty and roll it in your hands to warm it up to make it pliable. Then, apply the putty around the base of the sink strainer using your fingers, ensuring that it is evenly spread. Once you have applied the putty, you can place the sink strainer into the sink and press it down to secure it. Wipe off any excess putty with a clean cloth or your fingers before it hardens. It’s essential to make sure that the putty has fully sealed before reattaching any pipes or turning on the water supply. Applying the plumbers putty is a straightforward process and is crucial to the successful installation of a sink strainer.

Install the New Sink Strainer

Once you have successfully removed the old sink strainer, it’s time to install the new one. Start by applying a bead of plumber’s putty around the underside of the new sink strainer. This will help to create a watertight seal between the sink and the strainer. Make sure to cover the entire circumference of the strainer with the putty.

Next, place the new sink strainer into the sink hole from the top. Make sure that it fits snugly into the opening, and that the putty is between the sink and the strainer. Then, go underneath the sink and hand-tighten the locknut onto the threaded portion of the sink strainer. Use a wrench to tighten it just a bit more until it is snug. Once it’s tight, wipe away any excess plumber’s putty from around the edge of the strainer. Finally, turn on the water and test your work. If there are no leaks, then you have successfully installed your new sink strainer!

Tighten the Locknut and Attach the Tailpiece

Now that the sink strainer basket has been placed into the drain hole, it’s time to move on to the next step. The locknut and tailpiece will help secure the strainer in place and ensure that it functions correctly.

First, slide the rubber gasket up onto the tailpiece. Then, insert the tailpiece into the drain hole underneath the sink. Make sure it extends downwards towards the P-trap. Thread the locknut onto the tailpiece and tighten it by hand. You can use pliers if necessary, but be careful not to overtighten it as this may damage the seal.

Once the locknut is secure, attach the other end of the tailpiece to the underside of the sink drain. Again, make sure it is tightened without excess force. This will ensure that the strainer basket is properly positioned and will not move around when water is flowing through the sink. With the installation complete, the sink strainer should now be fully functional and ready for use.

Test the Sink Strainer for Leaks

After installing the sink strainer, it is important to test for leaks before considering the job complete. A leak can cause water damage under the sink, and the only way to avoid this is to ensure that the sink strainer is correctly installed.

To test the sink strainer for leaks, place a stopper in the sink to prevent water from draining. Fill up the sink with water until it is about halfway full. Allow the water to sit for a few minutes and observe if any water is dripping from under the sink. If you notice any leaks, you may need to tighten the nuts or add some plumber’s putty to create a waterproof seal.

Next, remove the stopper and allow the water to drain from the sink. Eliminating the water from the sink removes the pressure and gives you a clear view of any leaks. Remember to check the area around the sink for any moisture or signs of water damage. Fixing leaks promptly can prevent further damage, so take the time to test the sink strainer thoroughly.

The Conclusion

Installing a sink strainer is a simple and straightforward process that can be done with minimal tools and expertise. By investing some time and effort in this project, homeowners can prevent clogs and reduce the risk of plumbing blockages. A well-installed sink strainer can also save money on costly plumbing repairs and replacements in the long run.
