ABSTRACT:
A pneumatic pump is provided including a housing with an inlet aperture and an outlet aperture. A one way valve is mounted on the inlet aperture. A tube has a first end connected to outlet aperture and a second end positioned distant the housing. An air compressor resides in communication with the housing via a conduit. The air compressor serves to continuously elevate the pressure of air within the conduit. A solenoid valve allows the flow of the pressurized air to the housing only upon the actuation thereof. When the solenoid is actuated, the pressure within the interior of the housing is elevated above that of the exterior such that the valve is closed and the water within the housing is excreted through the outlet pipe. Finally, a timer is connected to the solenoid valve to actuate the same at user selected time intervals.
