Before you begin, turn off the water supply to your toilet - don't worry, it's not as scary as it sounds! You'll also need to drain the tank and disconnect the old fill valve - this is the part where you get to say goodbye to that annoyingly loud fill valve!
Now, take a deep breath and prepare yourself for the fun part - installing the new Kohler Silent Fill Valve Kit! It's like building with Legos, but instead of blocks, you get to work with shiny new plumbing parts!
