The fill valve controls the water flow into the toilet
tank after flushing. Common types include:

Float Ball Fill Valve – Uses a traditional ball float (common
in older toilets).
Pressure-Assisted Fill Valve – Provides faster refilling,
ideal for commercial toilets.
B. Outlet Valves (Flush Valves)
The flush valve releases water from the tank into the
bowl. Key types are:
Flapper Valve – A rubber seal that lifts when flushing (common
in residential toilets).
Tower Flush Valve – Uses a vertical cylinder for a stronger
flush.
Dual Flush Valve – Allows partial or full flush for water
efficiency.
