Frequently Asked Questions
Q. "How do I install the Fluidmaster 747 Fill Valve Service Kit?"
A. To install the Fluidmaster 747 Fill Valve Service Kit, you need to first turn the water supply to the toilet off. Using your fingers, turn the cap (usually blue but not always) connected to the copper riser tube a quarter of a turn counterclockwise to release the cap from the float assembly. A wrench should not be required. Once the cap is disconnected from the tabs keeping it in place, pull the float assembly straight off. Align the replacement Fluidmaster 747 fill valve service kit (float assembly) up and push it back into the cap and turn the cap clockwise a quarter of a turn until it tightens onto the tabs on the float assembly (fill valve service kit). Turn your water back on and check for leaks.
Q. "How do I find my Kohler model number?"
A. For our customers' convenience, we often list both the model number and the tank number of the Kohler toilets we offer parts for. If you already know your model number, that's great - but oftentimes this information won't be available to you. What you'll need to do then is look for the TANK number, which is right where you'd expect it to be on the inside of your toilet tank. Grab a flashlight, carefully remove your tank lid, place your lid somewhere safe, and look around inside your toilet tank for a 4-digit number beginning with either a 3 or a 4. Certain specialty toilets may have a 5-digit number starting with a 1. The number will be either molded into the porcelain or stamped on in blue or black ink. This is your tank number and you can use it to find the parts you need to fix your toilet.
Q. "There are letters and/or numbers after the model number inside my Kohler toilet tank - what do those mean?"
A. Kohler offers many variations of almost all their toilet models, and has experimented in the past with many different features. Typically, numbers (or a single letter/number combination like K4 or Y2) after the 4- or 5-digit model number indicate the color code for your toilet. If your model number is followed by letters, those usually have different meanings to indicate the features of your toilet or will indicate that you have a specialty Artist Edition toilet.
