the floating ball connected to the ballcock inside the tank that rises or falls with the changing water level in the tank
the fill valve that controls the flow of water from the supply line into a gravity-operated toilet tank. It’s controlled by a mechanism that floats in the tank water. When the toilet is flushed, the float drops and opens the ballcock. This releases water into the tank and/or bowl. As the water in the tank is restored, the float rises and shuts off the ballcock when the tank is full.
A ring that anchors the toilet to the floor and connects it to the closet bend. Also known as a Floor Flange.

a special valve installed on the main water line coming in to the home so that water entering the valve from municipal mains is constricted within the valve body. It reduces water pressure coming in to your home from the high level used by the water company down to a level that can be used in your home without damaging your fixtures.
