A toilet flapper allows your toilet to flush. So, when a flapper is damaged or leaking, it will result in a weak flush and cause the toilet to refill frequently. This can easily be fixed when you replace the flapper.

The Fluidmaster 502 toilet flapper will fix:

  • Weak and slow toilet flush
  • Double flush – toilet flushing twice
  • Running toilet – Water leaking from tank into the toilet bowl
  • Water waste – using too much water

You can now fix a weak toilet flush in minutes with this easy to install 502 flapper. This modern product is designed to fit 2-inch flush valves or toilets able to handle 1.28 to 3.5 GPF. The robust frame of the flapper will prevent excessive bending and early damage, making it a durable option.

You can turn the dial counter-clockwise for a long flush, or towards the right for a faster close and energy-saving flush. You have nine settings you can choose from. If you choose the closer to the last level, the quicker the flapper will close.

Not just simply a coating, Microban® is specifically built into the construction of our flappers to fight flapper breakdown and combat bacteria for a long lifespan.
