How To Remove Kitchen Sink Strainer: A Guide

To remove the kitchen sink strainer, start by using a screwdriver to undo the screws on the filter’s flange, then loosen the locking nut, and finally pull out the filter.

Tools Needed

When it comes to removing a kitchen sink strainer, you’ll need a few essential tools to get the job done efficiently. Having the right tools at your disposal will make the process easier and prevent any unnecessary frustration. Let’s take a look at the tools you’ll need.


A wrench is an essential tool for removing the locknut that holds the kitchen sink strainer in place. This tool provides the necessary torque to loosen the locknut, allowing you to detach the filter from the sink.


Using a plunger can help create suction to dislodge the sink strainer if it’s stuck in place. This tool can be handy if the filter is sealed with silicone or plumber putty, providing the necessary force to break the seal.


A screwdriver is necessary for removing any screws or fasteners that may be securing the kitchen sink strainer in place. It allows you to easily access and detach any components holding the filter, facilitating the removal process.


Before attempting to remove the kitchen sink filter, it’s essential to prepare the area properly. This will help make the process smoother and prevent any potential messes. For a problem-free experience, follow these steps carefully.

Turn Off the Water Supply

First and foremost, locate the shut-off valve that controls the water supply to your kitchen sink. It’s typically found underneath the sink, near the pipes. To turn off the water flow, turn the valve clockwise. This will prevent any water from unexpectedly spilling out while you remove the filter.

Clear Out The Sink

Remove any dishes, utensils, or debris from the sink before you begin. This will give you ample space to work and prevent any items from falling into the drain during the process. Taking a few minutes to clear out the sink beforehand will save you time and potential frustration later on.

Place A Bucket Underneath The Sink

Now, it’s time to grab a bucket. Place it directly underneath the sink, ensuring that it’s positioned to catch any water or debris that may fall during the strainer removal. Having the bucket handy will help contain any mess and make cleanup a breeze. Please don’t skip this step, as it could save you from a major cleanup later on.

Loosen Slip Nuts

To remove the kitchen sink filter, you will first need to loosen the slip nuts. These are the nuts that hold the drain pipe in place.

To do this, use a pair of slip-joint pliers or an adjustable wrench. Grip the slip nut firmly and turn it counterclockwise to loosen it. You may need to apply a bit of force, especially if the slip nut is tightly secured.

Disconnect The Drain Pipe

Once the slip nuts are loosened, you can disconnect the drain pipe from the filter. The drain pipe is the pipe that connects the sink to the rest of the plumbing system.

Place a bucket or a towel underneath the drain pipe to catch any water that may spill out. Then, loosen the slip nut that connects the drain pipe to the bottom of the filter. Once the slip nut is loose, you can carefully pull the drain pipe away from the filter.

Keep in mind that there may still be some water in the drain pipe, so be prepared to catch any remaining water that may come out.

Remove The Locknut

Finally, to remove the kitchen sink filter entirely, you will need to remove the locknut. The locknut is the large nut that holds the filter in place from underneath the sink.

Using a pair of slip-joint pliers or a locknut wrench, grip the locknut and turn it counterclockwise to loosen it. Once the locknut is loose, you can lift the filter out of the sink.

If the locknut is stubborn and won’t loosen, you can try using penetrating oil to loosen it or seek the help of a professional plumber.

Removing a kitchen sink strainer may seem intimidating, but by following these steps and using the right tools, you can easily remove it yourself. Remember to take your time and be careful to avoid damaging the sink or the surrounding plumbing.

Cleaning And Replacing

Cleaning and replacing the kitchen sink filter is a simple yet essential maintenance task that can ensure the efficient functioning of your sink. By properly cleaning the filter and drain pipe and then applying the plumber’s putty, you can easily remove and replace the kitchen sink strainer without the need to call a professional plumber.

Clean The Strainer And Drain Pipe

To clean the filter and drain pipe, start by removing the existing filter from the sink. Use a mild detergent or vinegar solution to scrub away any accumulated grime and debris. Be sure to thoroughly clean both the filter and the inside of the drain pipe to prevent clogs and maintain optimal water flow.

Apply Plumber’s Putty

After cleaning, apply a thin, even layer of plumber’s putty around the underside of the new strainer flange. This will create a watertight seal when the new filter is installed, preventing leaks and ensuring a secure fit. Wipe away any excess putty to achieve a neat and professional finish.

Install The New Strainer

When installing the new filter, ensure that the rubber gasket is in place and feed the strainer flange through the sinkhole. From under the sink, secure the filter by tightening the locknut. Wipe away any excess putty and test for leaks by running water through the sink. Once the new filter is in place and leak-free, your sink will be ready for use.

Finishing Touches

Want to know how to remove a kitchen sink strainer? It’s an easy process that can quickly improve your kitchen’s functionality. With just a few essential tools, you can do it on your own. Follow these steps and give your sink the finishing touch it needs.

After successfully removing the kitchen sink strainer, it’s time to put the finishing touches on your project. Here are the last few steps to complete the process seamlessly:

Reconnect The Drain Pipe

Now, it’s time to reconnect the drain pipe. Start by applying a plumber’s putty or a silicone bead around the base of the sink strainer. This will help create a watertight seal once everything is put back together.

Next, carefully screw the drain basket back into place, ensuring it is tightly secured. Use a wrench if necessary, but be cautious not to overtighten as it could cause damage.

After reattaching the drain basket:

  1. Connect the drain pipe using a slip nut.
  2. Align the pipe properly and tighten the slip nut until it is snug.
  3. Double-check that all connections are secure to prevent any future leaks.

Turn On The Water Supply

With the drain pipe reconnected, it’s time to turn on the water supply and test your work. Slowly open the water valves and observe if there are any leaks. Keep an eye on the connections and the area around the sink strainer.

Quickly shut off the water supply and examine the impacted area if you discover any leaks. Tighten any loose connections or consider applying more plumber’s putty or silicone where necessary. Repeat this step until there are no signs of leakage.

Check For Leaks

Once the water is flowing smoothly through the sink, it’s crucial to check for leaks thoroughly. Inspect all the connections, ensuring they are adequately tightened. Take a closer look at the drain pipe, the sink strainer, and the area underneath the sink.

To be extra cautious, place a small piece of tissue paper or a dry cloth under each connection point. Leave it there for a few minutes and then check if it is wet or if any water droplets are present. This will help you spot even the most minor leaks that might have gone unnoticed.

By paying attention to these finishing touches, you can confidently say that you have successfully removed and reinstalled your kitchen sink strainer. Enjoy your clean and fully functional sink without any worries of leaks or drainage issues.
