Device for maintaining the water level in pools, ponds and fountains

摘要

A device for automatically maintaining a desired water level in a water structure, such as a pond, pool or decorative water fountain. The device includes a reserve tank that is connected to the water structure by an open tube, or pipe, thus allowing the water level in the reserve tank to be the same as the water level in the water structure. When the water level in the structure drops, so does the water level in the device. When the water level in the device drops below a pre-defined level, a water supply switch is activated and more water is added to the reserve tank. As water is added to the reserve tank, water also flows through the open tube into the water structure, and the water levels in the reserve tank and in the water structure both rise at similar rates. When the water level in the reserve tank reaches a pre-defined full level, the water supply switch is de-activated and the flow of water to the reserve tank, and to the water structure, is shut off.
