Proper Installation Techniques
Proper installation of the new gasket is essential for guaranteeing an effective seal and preventing leaks in your Kohler toilet.
Begin by positioning the new gasket at the bottom of the toilet tank, and aligning it precisely with the flush valve hole. Ensure the gasket is flush with the tank’s base to avoid leaks.
Additionally, turn off the water supply before starting the installation to prevent any accidental flooding. Next, insert the flush valve into its designated hole and hand-tighten the mounting nut to secure it. Use pliers for an additional quarter turn, but avoid over-tightening.
Once the flush valve is in place, lower the tank onto the bowl, ensuring proper alignment with the holes. This careful approach sets the foundation for a reliable installation that minimizes the risk of future leaks.
Ensuring Secure Fit
A secure fit is essential for the longevity and efficiency of your Kohler toilet. Start by positioning the new gasket correctly on the bottom of the tank to align with the bowl. Make certain the flush valve washer is aligned over the flush valve before securing it with the mounting nut.
