The Pool Sentry operates much like a toilet tank float valve. Once positioned at the desired water level (commonly half‑tile height or skimmer level), a garden hose is attached, and water flow remains on. When water level drops, the float opens the valve to refill. Once the float rises to its set point, it automatically shuts off the water flow.
This unit is especially well-suited for situations where permanent plumbing isn’t practical—for example, during pool acid wash, for vacation properties, rental units, or temporary setup—and it helps avoid pump damage due to low water.
Assembly Tip: Snap together the fill tube and valve into the base, fill the internal pouch with pea gravel, attach a heavy-duty reinforced hose, and adjust the float height. No tools are needed.
