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.
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.

of the trap will be 1/8 larger than the maximum-sized ball that can
pass through it.

reach inside the tank.

vertical tube inside a toilet tank (usually part of the flush valve)
that directs water into the bowl in case the ballcock malfunctions. If
the ballcock does not shut off properly, water will drain through the
overflow tube into the bowl, and flow harmlessly over the dam and out
the drain. This prevents potential water damage caused by the tank
overflowing and indicates to the user that there is a problem by a
"constant running" condition. On most toilets, the overflow tube also
has a refill tube flowing into it. The refill line directs water from
the ballcock through the overflow tube to the bowl after the siphon
