A Kohler pop-up assembly is an essential component in maintaining an efficient and clog-free sink drain system. Whether you are renovating your bathroom or simply replacing an old assembly, mastering the installation process is crucial for seamless functionality. In this blog, we will provide a step-by-step guide on how to install a Kohler pop-up assembly, ensuring a hassle-free sink drainage system.

Step 1: Gather the Necessary Tools and Parts Before diving into the installation process, ensure you have all the required tools and parts. You will need a wrench, pliers, a screwdriver, plumber’s putty, and the Kohler pop-up assembly kit.

Step 2: Prepare the Sink and Drain Hole Turn off the water supply to the sink and place a towel or cloth under the sink to catch any excess water. Remove any debris or old putty from the drain hole to create a clean surface for the new pop-up assembly.

Step 3: Apply Plumber’s Putty Take a small amount of plumber’s putty and apply it around the underside of the flange of the new pop-up assembly. This creates a watertight seal between the assembly and the sink.

Step 4: Insert the Pop Up Assembly Insert the pop-up assembly into the drain hole from the top of the sink. Ensure the pivot rod aligns with the slot in the stopper.

Step 5: Secure the Pop Up Assembly From under the sink, secure the pop-up assembly by tightening the nut onto the threaded rod. Use pliers or a wrench to ensure a snug fit, but avoid overtightening to prevent damage.

Step 6: Connect the Pivot Rod Attach the pivot rod to the lift rod on the back of the faucet. Adjust the lift rod to control the movement of the stopper.

Step 7: Check for Leaks Turn on the water supply and let the water run for a few minutes. Check for any leaks around the pop-up assembly and tighten any connections if necessary.

Step 8: Test the Pop Up Assembly Test the pop-up assembly by pushing down on the stopper and lifting it back up. Ensure that the stopper moves smoothly and that the sink drains efficiently.

Step 9: Make Final Adjustments If the stopper does not move smoothly or if there are any issues with the drain, make any necessary adjustments or reinstall the pop-up assembly following the same steps.


Installing a Kohler pop-up assembly is a straightforward process that can significantly improve the efficiency of your sink drainage system. By following this step-by-step guide, you can master the installation and ensure a leak-free and smoothly functioning pop-up assembly. Remember to always use the right tools and take your time during the process to achieve the best results.
