Abstract
A water saving device is provided in the form of a flow control valve, which may be installed in the refill tube for the toilet bowl of a water closet, and which may be adjusted to establish the proper amount of refill water to flow into the toilet bowl after each flush, so as to avoid wastage. The device, in one of its embodiments, may be installed in the refill tube of an existing water closet. The device can also be mounted directly on the main toilet valve unit as a built-in item for newly manufactured toilets.
