Adjusting the flush on a Kohler Cimarron toilet will only take a few minutes. The most common adjustment you need to make is to the water level in the toilet tank. The water level controls to some degree the flushing power of the toilet. If the water level is too low, the toilet will not have enough power to properly evacuate the bowl. If the water level is set to high, the toilet will flush great, but you will be wasting water.
Things You'll Need
- Old bath towel
- Phillips-head screwdriver

Remove the Kohler Cimarron toilet tank lid from the back of the toilet. Place the lid carefully to the side on an old bath towel, out of the work area. The bath towel will cushion the lid and prevent accidental breakage. There is no need to turn the off the water supply when adjusting the flush on a Cimarron toilet, in fact, you need the water on in order to set the water level correctly.
Flush the toilet by pressing down on the handle. Allow the toilet to refill until the water fill valve shuts off. If the water fill valve does not shut off, replace it. The water fill valve is the tall gray and black plastic tube in the left side of the toilet tank. Find the water fill line marked on the inside of the tank behind the fill valve. If you cannot see the water fill line on the back of the tank, select a point approximately one inch below the top of the fill valve as the water fill line.
Adjust the water level inside the tank to meet the water fill line mark. Flush the toilet, and as the water fills, use a Phillips-head screwdriver to turn the water adjustment screw which is on the side of the water fill valve. Turn the screw clockwise to increase the water level in the tank, and counterclockwise to lower the water level in the toilet tank. Flush the toilet a couple of times to insure proper operation. When you are satisfied you have the water level set, carefully replace the toilet tank lid.
