Ballcock
The mechanism that controls the flow of water into a gravity-operated toilet tank. The ballcock is controlled by the float mechanism floating in the water in the tank. When the toilet is flushed, the float drops and opens the ballcock, allowing water to enter the tank and/or bowl. The float rises as the water level in the tank is restored, and shuts off the ballcock when the tank is completely filled. Also referred to as a float valve.
Ball Passage
Refers to the size of a ball that can pass through the trapway of a toilet. Standards are established based on minimum-sized ball passage. Ball passage also relates to trapway size. Generally speaking, the size of the trap will be 1/8 larger than the maximum-sized ball that can pass through it.
Barrier-Free
A feature that provides better accessibility in the bathroom; barrier-free sinks craft an indentation on the front, allowing closer, easy access; barrier-free showers implement a low receptor lip for a smooth, easy transition in and out of the shower.
Bidet
A personal hygiene fixture with hot and cold water supply for genital and perineal cleanliness.
