The Kohler 1025330-CP is a right-hand trip lever designed for use in Kohler toilets. It’s a part of the toilet that is connected to the flapper and is used to flush the toilet. When you push the lever, it lifts the flapper from the valve, allowing water to flow from the tank into the toilet bowl. When standing in front of the toilet the lever will be on the right hand side of the tank.

The “CP” in the model number stands for “Chrome Polished”, which means the lever has a shiny, chrome finish that can match the decor of many bathrooms.
