Wipe the area to remove water or dirt.
Keep a towel nearby for spills.

Take Out The Old Strainer

Now, remove the old kitchen sink basket strainer. Follow the right steps for a simple job. First, disconnect the drain pipes under the sink. Then, unscrew the strainer from the sink opening. This prepares your sink for the new part.

Disconnect Drain Pipes

Look under the sink for the drain pipes. They connect to the basket strainer. Place a bucket below to catch any spilled water. Loosen the slip nuts on the drain pipes. Turn these nuts counterclockwise. Carefully pull the pipes away from the strainer.

Place a bucket under the pipes first.
Use pliers or your hands to loosen nuts.
Remove the pipes gently to stop damage.

Unscrew The Strainer

Move to the sink top now. Use a wrench or pliers to hold the locknut below the sink. Turn the locknut counterclockwise to loosen it. The locknut will be loose now. Lift the basket strainer out of the sink drain. Next, clean the drain area.

Hold the locknut tightly with your wrench.

Clean The Drain Opening

Cleaning the sink drain opening is very important. A clean drain helps the new strainer fit well. Removing dirt and grime prevents clogs later. It also stops bad smells. A clean area makes the whole process faster.

Remove Old Debris

Clean With Soapy Water

Mix warm water with a mild dish soap. Use this cleaning solution. Wipe the drain opening with a cloth or sponge.

Dip the sponge in the soapy water mix.
Scrub the drain opening gently.
Rinse the area with clean water.
Dry with a clean towel.

Use Vinegar For Stains

Pour white vinegar into the drain opening. Do this if stains remain. Let the vinegar sit for about ten minutes. This will dissolve the buildup. Scrub the area again after soaking. Rinse thoroughly with water. Vinegar cleans well without harsh chemicals.

Dry The Drain Opening

Completely dry the drain opening now. Use a paper towel or clean cloth. Drying removes all moisture. This prevents water from trapping under the strainer. Trapped water can cause leaks or corrosion.

Put In The New Strainer

Installing a new kitchen sink basket strainer is simple. This part stops trash from clogging your drain. This guide shows you the correct installation process.

Apply Plumber’s Putty

Take some plumber’s putty on your fingers. Roll it into a long, thin rope shape. Put the putty rope around the strainer’s bottom edge. This seals the sink and stops leaks.

Position Strainer And Tighten

Insert the basket strainer into the sink drain hole. Do this carefully. Press it down firmly to spread the putty. Go under the sink now. Slide the rubber gasket and metal washer on. Put them onto the strainer’s threaded part. Then, screw the locknut on tightly. This holds everything in place.

Reconnect the drain pipes after installing the new strainer. This step is essential. A proper connection stops leaks. It ensures water flows out smoothly. This guide shows you how to attach the gaskets. It also explains how to secure the locknut and pipes.

Attach Rubber Gaskets

Clean the sink drain area well.
Slide the rubber gasket onto the drain pipe.
Be sure the gasket sits evenly.
Press the gasket firmly against the sink's bottom.

Secure Locknut And Pipes
