Understanding The Causes Of A Running Kohler Toilet

A running Kohler toilet can be caused by a faulty float valve, a worn-out flapper, or a malfunctioning fill valve. The float valve, responsible for regulating the water level, may be damaged or misaligned, causing continuous water flow. On the other hand, a worn-out flapper fails to create a proper seal, leading to water leakage and constant running.

Lastly, a malfunctioning fill valve may not shut off properly, causing water to continuously refill the tank. To fix these issues, it is important to inspect and replace any damaged or worn-out components. Regular maintenance and timely repairs can help prevent a running toilet, ensuring efficient water usage and saving money on utility bills.

Remember, a running Kohler toilet should not be ignored, as it can lead to water wastage and potential damage to the plumbing system.
