The Pool Sentry™ is used to maintain the water level of a pool, spa or pond automatically and unattended. As the float drops, the water turns on. When the float reaches its set height, the water shuts off. You can adjust the float to any desired level, usually a point halfway on the tile line or skimmer.
NOTE: The water stays on at all times when the Pool Sentry is in the pool. Because the hose is under constant water pressure, it is essential that you use a heavy-duty, reinforced hose.
