  • Patent number: 7137223
    Abstract: A filling station for watering cans comprises a water tank with a closable lid. A float valve mechanism is attached to the inside of the tank, and is connected to a water line or hose. In use, the filing station is placed in a garden area, with the hose running between the float valve and a house water spigot. Subsequently, the spigot is turned on (and is left on), supplying water to the float valve. The float valve allows water into the tank until the tank is full. For watering, the cover is opened, exposing the water and a dipping area, which is dimensioned to accommodate a conventional watering can. Then, the watering can is dipped into the water until full, and is used to water plants. When the water level in the tank falls below a certain level, the float valve automatically activates to refill the tank.
