• Leaking: Often caused by worn seals or cracks in the valve.
• Incomplete Flushing: Occurs when the valve doesn’t open fully or closes prematurely.
• Constant Running Water: Indicates a failed seal that prevents proper closure.

• Adjustable wrench
• Screwdriver (flathead and Phillips)
• Towel or sponge for water cleanup
• Replacement flush valve kit (specific to your Kohler model)
