The Pool Sentry Automatic Water Leveler (SKU 937) is a self‑adjusting water‑level control system designed to keep your pool, spa, or pond at the proper height without supervision. It attaches to a standard garden hose and automatically adds water whenever the float detects a drop in water level.

This prevents pumps from running dry, protects equipment, and eliminates the need for manual filling. The unit is portable, easy to assemble, and requires no tools. Simply place it at the pool edge, connect a hose, and let the float system maintain the correct water level.
