Automatic Water Level Maintenance for Ponds and Basins The Atlantic Water Gardens auto fill kit is an automatic water level control valve assembly that maintains a constant water level in pond, fountain basin, or waterfall reservoir installations without manual monitoring or intervention. As water evaporates or is lost through splash-out, the float valve opens to admit a controlled supply of fresh water — maintaining the target level precisely and continuously without overfill risk. Once the water reaches the set level, the valve closes automatically. How It Works A float-controlled valve connects to a standard garden hose or low-pressure supply line. As the water surface drops below the set point, the float descends and opens the supply valve, admitting water until the float rises to the shutoff position. The mechanism is entirely mechanical — no electricity, no programming, and no sensors to calibrate or maintain. Adjust the desired water level by repositioning the float arm per the included instructions. Installation The kit includes the float valve assembly, supply fitting, and mounting hardware. Connect to a standard 1/2-inch or 3/4-inch garden hose fitting supply. Position the valve at the pond or basin edge to the desired water level. For best results, use in conjunction with an outdoor GFCI outlet nearby to power any existing water feature pumps.
