Fill Valves for Kohler Toilets

Q. "The GP1138930 comes with some colored inserts. What are those for?"
A.Since the Kohler GP1138930 is a replacement for a variety of fill valves, it comes with a selection of color coded flow restrictors. To select the correct insert, check your old fill valve (the one you're replacing) and use the same color restrictor on your new GP1138930 fill valve. See example of the four included restrictors.

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.

Q. "What are the most commonly replaced toilet parts?"
A. This depends on several factors; each time you use your toilet the trip lever, flapper, and fill valve are operated. You will find, however, that the flapper and fill valve are the parts most exposed to water and will be the first ones to wear out in most cases.
