Frequently Asked Questions

Q. "You mention the Kohler repair kit #GP30420 fits many Kohler single lever kitchen faucets. How do I know if it will fit my faucet?"
A. The information we have obtained from Kohler says the GP30420 repair kit fits the following faucets; Antique model numbers 168, 169, 170, and 171. Forte model numbers 10411, 10412, 10413, 10415, and 10416. Fairfax model numbers 12171, 12172, 12173, 12175, and 12176. Coralais model numbers 15171, 15172, 15173, 15175, and 15176. Coralais Decorator model numbers 15071, 15072, 15073, 15075, and 15076.

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.
