The submersible water pump system is designed to rest at the bottom of a water reservoir (with a minimum depth of 2 inches) to recirculate water, thus producing water flow. The plug and receptacle connectors attach to distribute electrical power from the rechargeable battery to the water pump to allow operation. The submersible, rechargeable, battery-operated water pump system is cordless, thus providing safe, portable, independent operation without the use of electrical cords or outlets. ## Claims ### Claim 1 A decorative, water fountain pump system comprising, in combination: a water-submersible, battery-operated water pump having a vertically oriented discharge and configured to provide a flowrate of water of between 200 liters per hour and 720 liters per hour, the pump being securable to a water reservoir configured to hold a supply of water having a top surface thereon; a waterproof plug connector electrically connected to the pump and configured to provide waterproof, electrical communication with a waterproof receptacle connector; a waterproof, rechargeable battery substantially contained within a waterproof dip-coating; the waterproof receptacle connector electrically connected to the battery and configured to receive the waterproof plug connector, thereby providing waterproof, electrical communication therebetween; the pump system positioned completely within the water reservoir, thereby being completely submergible within the supply of water; whereby the pump and the battery are electrically connected by connecting the waterproof receptacle connector and the waterproof plug connector; and whereby operating the pump in the supply of water provides the flowrate of water to the vertically oriented discharge, thereby pumping water upward and beyond the top surface of the supply of water. ### Claim 2 (depends on 1) The decorative, water fountain pump system of claim 1, wherein the battery produces a voltage of between 5.5 volts and 8.6 volts. ### Claim 3 (depends on 1) The decorative, water fountain pump system of claim 1, wherein the battery is dip-coated with a waterproof synthetic rubber. ### Claim 4 (depends on 1) The decorative, water fountain pump system of claim 1, the pump being configured to operate at a voltage of between 5.5 volts and 9 volts. ### Claim 5 (depends on 1) The decorative, water fountain pump system of claim 1, wherein the pump is a centrifugal-type pump. ### Claim 6 (depends on 1) The decorative, water fountain pump system of claim 1, the system further being configured to be portable. ### Claim 7 A decorative, water fountain pump system comprising, in combination: a water-submersible, battery-operated water pump having a vertically oriented discharge and configured to provide a flowrate of water of between 200 liters per hour and 720 liters per hour, the pump being positionable within a water reservoir configured to hold a supply of water having a top surface thereon; a waterproof plug connector electrically connected to the pump and configured to provide waterproof, electrical communication with a waterproof receptacle connector; a waterproof, rechargeable battery substantially contained within a waterproof dip-coating; the waterproof receptacle connector electrically connected to the battery and configured to receive the waterproof plug connector, thereby providing waterproof, electrical communication therebetween; the pump system positioned completely within the water reservoir, thereby being completely submergible within the supply of water; whereby the pump and the battery are electrically connected by connecting the waterproof receptacle connector and the waterproof plug connector; and whereby operating the pump in the supply of water provides the flowrate of water to the vertically oriented discharge, thereby pumping water upward and beyond the top surface of the supply of water. ### Claim 8 (depends on 7) The decorative, water fountain pump system of claim 7, the pump further having a suction cup disposed thereon configured to be securable to a generally smooth surface provided on the water reservoir. ### Claim 9 (depends on 7) The decorative, water fountain pump system of claim 7, wherein the battery produces a voltage of between 5.5 volts and 8.6 volts. ### Claim 10 (depends on 7) The decorative, water fountain pump system of claim 7, wherein the battery is dip-coated with a waterproof synthetic rubber. ### Claim 11 (depends on 7) The decorative, water fountain pump system of claim 7, wherein the pump is configured to operate at a voltage of between 5.5 volts and 9 volts. ### Claim 12 (depends on 7) The decorative, water fountain pump system of claim 7, wherein the pump is a centrifugal-type pump. ### Claim 13 (depends on 7) The decorative, water fountain pump system of claim 7, the system further being configured to be portable. ### Claim 14 A decorative, water fountain pump system comprising, in combination: a water-submersible, battery-operated, centrifugal water pump having a vertically oriented discharge and configured to provide a flowrate of water of between 200 liters per hour and 720 liters per hour, the pump having a suction cup disposed thereon configured to be securable to a generally smooth surface provided on a water reservoir, the water reservoir configured to hold a supply of water having a top surface thereon; the pump further being configured to operate at a voltage of between 5.5 volts and 9 volts; a waterproof plug connector electrically connected to the pump and configured to provide waterproof, electrical communication with a waterproof receptacle connector; a waterproof, rechargeable battery substantially contained within a waterproof, synthetic rubber dip-coating and configured to produce a voltage of between 5.5 volts and 8.6 volts; the waterproof receptacle connector electrically connected to the battery and configured to receive the waterproof plug connector, thereby providing waterproof, electrical communication therebetween; the pump system positioned completely within the water reservoir, thereby being completely submergible within the supply of water; whereby the pump and the battery are electrically connected by connecting the waterproof receptacle connector and the waterproof plug connector; and whereby operating the pump in the supply of water provides the flowrate of water to the vertically oriented discharge, thereby pumping water upward and beyond the top surface of the supply of water; and wherein the system is configured to be portable.
