The flapper valve is the most common type, consisting of a rubber or plastic flap that covers the valve seat. When the toilet is flushed, the flapper opens, allowing water to flow into the bowl. The fill valve, on the other hand, is designed to refill the tank after flushing, ensuring a consistent water level.

  • Inefficient flushing
  • Leaks and water damage

To prevent these problems, it is crucial to choose the right valve for your toilet and install it correctly. This may involve consulting a professional plumber or following the manufacturer's instructions.
