Skeleton of a Toilet

The tank and bowl are the two primary components of a toilet. The bowl stores water and is connected to the drain that waste and used water are disposed through. The tank, which is raised above the bowl has facilities for flushing clean water into the bowl and refilling the tank, and holds extra water for replenishing the bowl.

Water distribution to the tank is managed by a device known as a ballcock, which is connected to the water supply. After a flush, the water in the tank quickly descends into the bowl, and the pressure pushes the bowl’s waste water into the drain. A float, ball, or pressure gauge detects the decrease in water level, and this signals the ballcock to replenish the tank.
