  • General Operations

  • How do I use my Lil' Sprout Pump?

    All three models of the Lil'Sprout operate generally the same way. Take the Lil'Sprout outside and connect to your garden hoses; the input is the female (hidden connector threads), the output the male (visible connector threads). Insure the other end of the input hose is connected to a rain barrel or immersed in water and the rain barrel faucet is turned on, and that the output hose is placed where you want the water to flow. Check the hoses to insure they are connected tightly to prevent leaks. The toggle switch is located in approximately the center. When flicked to the solar side, the solar panel and battery are activated and the pump operates. When the switch is flicked to the AC plug-in side, and the plug is plugged into an AC outlet, the water pump operates on AC. (There are two switches on the SR Model only, see SR Model operating instructions below).

  • Can I hook my Lil' Sprout up to a sprinkler?

    Yes. It will run on solar/battery for 2- 4 hours and then must be recharged. If plugged-in and switched to AC, it will run indefinitely. (Caution) Although the pump runs dry it should be shut down when the water source dries-up.

  • Will the Lil' Sprout get clogged with leaves, dirt, etc if I am pumping out a flooded area or pond?

    Yes. There strainers available at most hardware stores that fit on the garden hose or small cloth filters used for cloths dryers can be wrapped and tied around hose ends.

  • How can I recharge my Lil' Sprout with solar?

    Simply leave it open in the sun. Depending on the brightness of the sun the battery will take 3 to 5 hours to recharge. .

  • How can I recharge my Lil' Sprout with electric?

    Only the SR Model is designed to recharge internally with electric. (see SR operating instructions above). Otherwise, a standard vehicle battery charger can be used to recharge the battery by clipping onto the battery terminals.

  • How do I run my Lil' Sprout from my car, truck or tractor battery?

    Only the model U is designed to be used for remote-clip-on operation. (See operating instructions for the model U).

  • How many recharges is my battery good for?

    These batteries life expectancy is very highly rated. A typical battery usage is three years. Be sure to match the battery 12 volts, and connectors which are standard for these type batteries.

  • Utility Model U

  • What is the Utility Model typically used for?

    The Utility model is our austere model and typically used in fields and remote water streams and ponds for filling cattle and other animal cisterns and troughs, and where there is a vehicle available to clip-on the battery leads. It is also used in barns and other buildings where there is AC access

  • How does the Model U operate?

    The Model U has a clip-on mode and an AC mode of operation. For remote (field or pasture) operations, it is clipped on to a tractor or other vehicle battery; for barn applications where there is AC available, it is plugged into the AC outlet. (there is an added 25 ft extension cord included). Simply, connect garden hoses to the Lil' Sprout and flick the switch toward the battery-connectors for remote battery operation and toward the AC plug-for AC operation.

  • Solar Model S

  • What is the S Model typically used for?

    The S model is used universally for almost any application. It can be used with rain barrels, ponds, streams or any other water source, including for removing water from flooded cellars and other buildings. Applications are as many as you can create: irrigation of flower and vegetable gardens, shrubs, small orchards, greenhouses and tunnels, removing water from flooded areas, transferring water to remote ponds, bird dishes, fountains, pools etc., washing vehicles and outsides of houses and other buildings and windows.

  • How does the Model S operate?

    Connect the garden hoses and tighten the Input hose to the female connector and the output hose to the male connector. Open the top. On the inside of the top the solar panel is already operating. Simply flip the switch toward the solar panel and the water pumps water in the solar mode; flip the switch toward the AC plug, and plug into an AC outlet, and the water pump operates in the AC mode. The water pump will operate on a full charge for 2 to 4 hours in the solar mode, and operate in the AC mode indefinitely. A complete solar recharge takes between 3 to 6 hours depending on the brightness of sun. When shut-off at the end of the output hose, the pump shuts down until the hose is re-opened. In the event the source water dries up the pump will run dry without damage, but needs to be shut down ASAP.

  • The Solar Recharge Model (SR):

  • What is the Solar Recharge Model typically used for?

    The solar model is our all-purpose model and is used universally for almost any application. Additionally when plugged into an AC outlet and the switch flicked to charge it will recharge the battery in approximately 1 hr. It can be used with rain barrels, ponds, streams or any other water source, including for removing water from flooded cellars and other buildings. Applications are as many as you can create: irrigation of flower and vegetable gardens, shrubs, small orchards, greenhouses and tunnels, removing water from flooded areas, transferring water to remote ponds, bird dishes, fountains, pools etc., washing vehicles and outsides of houses and other buildings and windows.

  • How does the Model SR operate?

    Connect the garden hoses and tighten; the Input hose to the female connector and the output hose to the male connector. Open the top. On the inside of the top the solar panel is already operating. There are 2 switches, one DC and one AC. Flip the DC switch toward the solar panel and the water pump operates, flip the same switch in the other direction and the water pump shuts off. When operating in the AC mode flip the AC switch toward the AC plug and plug-in to an AC outlet, and the water pump operates. Flip the switch in the opposite direction, the water pump shuts down, and the battery is charging. It will take about 1 hr for the battery to charge in this way. The SR Model has both battery solar charging and AC charging. The water pump will operate on a full battery charge for 2 to 4 hours and in AC mode the pump will operate indefinitely. A complete solar recharge is between 3 to 6 hours depending on the brightness of sun. An AC recharge is approximately 1 hour. When water is shut-off at the end of the output hose, the pump shuts down until the hose is re-opened. In the event the source water drys-up the pump will run dry without damage, but the pump should be shut down if running dry ASAP.

  • Rainwater Harvesting with the Lil' Sprout

  • How can I attach my Lil' sprout to a water source?

    The Lil' Sprout has standard garden hose connectors. Your input hose extends from a rain barrel, pond or other water sources to the female connector (hidden threads); your output hose from the male connector (visible threads) to the garden, shrubs and your other applications.

  • I want to set up a rainwater collection system. What is the best way to do this?

    All of the hardware stores have rain barrels with collectors that are often customized as a total system. The instructions are rather simple. The store will be able to answer and discuss any of your additional concerns.
