How Does Aqua Pro Work?

Replenishing the battery causes the float to rise and releases the valve from its recess. As a result, the water is able to wash around the valve lens and the water stream moves the valve up. Then the water pressure holds the valve lens against the valve-sealing ring and keeps it closed. Order your specific kit at the bottom of this page.

These kits are designed for group 24, 27, and 31 with cell spacing that is NOT the standard 1 5/8" center to center.  This  only works on batteries with .75" press in style caps.

Aqua Pro is manufactured in Germany by Rover and Rover.  This style of valve is available as individual valves and can be custom fit in strings of six valve connected via clear tubing.  Just insert six valves into the battery cell hole, measure and cut clear tubing to connect valve strings.  It't that easy. This valve is designed to press into the cell hole just like the standard cap that you would remove.

For standard group 24, 27, and 31 batteries with 1 5/8" cell spacing it is recommended that you use the standard Qwik-Fill product- Link to Qwik-Fill.  However the Aqua Pro valve will work just as well in the standard battery.

  • Multi Pressure
    AquaPro's shut-off valve is able to operate with the low gravity pressure created by an elevation of 1.5 m (5 ft) all the way through to the high pressure of 45 psi (3 bar) - the widest range of all available fill systems in the world!

  • High Speed
    AquaPro's shut-off valve has the largest water passage of all watering systems--making it to the fastest!

  • Air Immunity
    AquaPro's shut-off valve is virtually immune to air in the hose system WITHOUT PURGING!

  • Reliable Function
    AquaPro's shut-off valve uses the hydrodynamic and hydrostatic forces of water, always adapting to existing pressure conditions. This makes AquaPro® more reliable than any other watering system.

  • Precise Filling
    AquaPro's shut-off valve ensures an absolutely precise electrolyte level from the first cell to the last. Every fill cap will stop replenishing exactly when the required electrolyte level is reached in its cell.

  • Incline Tolerance
    AquaPro's shut-off valve works perfectly, even if the battery is 15 degrees out of level, because of the movable linked valve. The user does not have to worry if the vehicle is on an incline or level.

  • Series Connection
    AquaPro's shut-off valve allows the fill caps to be strung together theoretically without limitation. No parallel branches are needed.
