Q. "How do I adjust the water level for the 84499 conversion kit?"
A. As with any conversion or "will fit" replacement kit, you might need to make slight adjustments for the unit to function exactly like your original valve did. For the 84499 fill valve, you simply turn the adjustment screw counterclockwise to raise the water lever or clockwise to lower the water level. You may need to flush the toilet and keep turning either way until the water level in the tank matches the line on the flush valve overflow tube. If you're not sure where to find the adjustment screw or water level, view our handy parts diagram.

Q. "The 84499 1B1X conversion kit includes a diverter assembly on the fill valve but you also offer other 1B1X fill valves without a diverter assembly. If I purchase a 1B1X fill valve separately should I order the one with a diverter or without a diverter?"
A. If your toilet fill valve currently has a diverter, we believe you should purchase a 1B1X with a diverter. Older toilets came with 1B1X fill valves without a diverter. The diverter assembly was invented as a water saving device for the 1B1X fill valve and was added in later years after stricter laws regarding water saving toilets came into effect. When properly installed, the diverter assembly allows water to flow into the bowl and the tank at the same time. As the water in the tank reaches a certain level, the float on the diverter assembly closes off the water flowing into the bowl and diverts that water so it flows into the tank instead. The extra flow of water into the tank then helps fill the tank quicker causing the float ball to rise and turn off the fill valve completely. Without a diverter, the 1B1X fill valve will continue to flow water to the bowl the entire time the tank is filling up. The #84499 1B1X conversion kit was designed by Kohler to upgrade their older toilets to be more water saving. If you do choose to install the 1B1X-WF fill valve you will just put the tube into the hole for the bowl flush, and water will flow until the tank fills up through the tank tube.

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.
