Quick Answer
To install a kitchen sink strainer basket, you need to first remove the old strainer basket by loosening the locknut underneath the sink. Clean the area around the sink hole and insert the new strainer basket. Secure the locknut by tightening it using pliers. Check if the basket is seated properly and test if the water flows through the drain smoothly.

Gather the necessary tools and supplies

Gathering the necessary tools and supplies is the first and most important step before installing a kitchen sink strainer basket. Having the right tools on hand can make the process quicker and easier, while also ensuring a professional-looking finish.

To begin, you’ll need a sink strainer basket kit that typically includes the strainer basket, locking nut, washer, and gasket. You will also need a matching wrench to tighten the strainer basket and a plumber’s putty to seal the sink. Other helpful tools include pliers for removing the old strainer basket, a screwdriver, and a clean cloth for wiping down the sink and the basket.

When purchasing the strainer basket kit, keep in mind the size and shape of your sink to ensure the proper fit. Depending on your sink’s configuration, you may also need to purchase a tailpiece and a disposer flange. Taking inventory of all necessary tools and supplies before beginning the project will ensure a smooth installation process and professional-looking finish.

Remove the old strainer basket

Removing the old strainer basket from your kitchen sink is the first step towards installing a new one. Before you begin, ensure that you have all the necessary tools and materials ready, including a plumber’s wrench, a screwdriver, and a new strainer basket.

First, turn off the water supply to the sink and place a bucket or a towel underneath the sink to catch any water that may spill out during the process. Next, use the plumber’s wrench to loosen the locknut that secures the old strainer basket in place.

Once the locknut is loose enough, use your hands to twist the old strainer basket anticlockwise until it comes out of the sink. Be mindful of any old putty or gasket that may come off with the old strainer basket. Clean any debris or residue around the sink hole before proceeding with the next step. With the old strainer basket removed, you are now ready to install a new one.

Prepare the sink for installation

Before starting the installation, it’s important to prepare the sink area properly. First, make sure the sink is completely emptied, and clean any residue or debris from the sink’s surface to get rid of possible waste build-up or rust. Ensure that the area is sufficiently lit and free from any obstacles to move around quickly.

Next, inspect the sink’s drain hole to make sure that it’s in good condition and free from any cracks or damages. The absence of a ring or collar on the opening requires you to purchase one before proceeding. This ring or collar should be placed on the drain hole before installation. The right collar fitting guarantees a secure and tight connection of the strainer basket later on. Remember to take extra precautions and double-check that the sink is clean and in good condition to avoid any issues in the future.

Now that you have removed the old strainer basket, it’s time to install the new one. Start by applying plumber’s putty around the perimeter of the drain hole. Make sure you apply the putty evenly to the entire area, leaving no gaps or spaces. Once the putty is applied, insert the new strainer basket into the drain hole, pressing it firmly into place. Secure the strainer basket in place by tightening the locknut underneath the sink. Use your pliers to hold the strainer basket steady while you tighten the locknut with your other hand. Make sure that the strainer is level and centered as you tighten the locknut. Wipe off any excess plumber’s putty that oozes out from the edges of the strainer basket.

Installing a kitchen sink strainer basket is a quick and easy DIY project that can save you money on plumber’s fees. This is a task that even a beginner DIYer can do with some basic tools and supplies. Just make sure to follow the steps carefully, and you’ll have a new strainer basket installed in no time.

Tighten the locknut and basket assembly

After ensuring a proper fit of the kitchen sink strainer basket, it is time to secure it tightly. It’s important to note that the locknut and basket assembly should be installed carefully and correctly to avoid any leaks. As such, the basket assembly should be lowered into the strainer hole and centered in it.

Next, slide the rubber gasket onto the bottom of the basket assembly. Then, place the locknut on top of the gasket and tighten it by hand. Be sure to hold the basket steady with one hand and use the other hand to tighten the locknut with a wrench. Use moderate force to tighten the locknut and make sure the basket is secure and aligned with the sink’s drain. This step ensures that the kitchen sink strainer basket is installed correctly and without leaks.

Check for leaks and proper drainage

Once you have installed the kitchen sink strainer basket, it’s important to check it for leaks and proper drainage. Start by running some water in the sink, letting it fill up to the brim. After a minute or so, turn off the faucet and check the bottom of your sink for any signs of leakage. If you notice any water dripping, it could be a sign that the strainer basket is not properly installed or tightened. If that’s the case, remove the strainer basket and try again.

Next, you’ll want to check for proper drainage. Turn on the faucet and let the water run for a few minutes, allowing it to drain through the strainer basket. If the drainage is slow, it could be a sign of a clogged drain. Use a plunger or drain cleaner to remove any clogs. Finally, check the strainer basket for any signs of debris that may have accumulated during the installation process. Clean it out thoroughly before using your sink to avoid any potential problems down the line.
