Automatically maintain water levels in ponds, decorative water features, and pools with an auto-fill valve.

Reduces time-consuming maintenance versus manually filling with a hose.
Helps protect pump from running dry
Better for pond ecosystems by adding small amounts of water as needed, eliminating large water chemistry swings (including chlorine/chloramine levels) that occur during manual top-offs
