Abstract
A watering can includes a pump and a snorkel which can be used to draw water out of a vessel and into the watering can. The snorkel device is put into a vessel from which water is to be evacuated and the pump is cranked in order to start the flow of water from the vessel and into the reservoir of the watering can. In some embodiments, the pump is a peristaltic pump which includes a mode where the pump is fully disengaged and fluid may flow freely from the snorkel, through the pump, and into the reservoir of the watering can. This allows the operator to use the pump to start a siphoning process which evacuates the remainder of the water from the vessel without further pumping. When not being used to draw water out of a vessel, the watering can may be used in the ordinary manner.
