The Paradise Pool Sentry M3000 Water Leveler is a device used to maintain pool water levels automatically without the need for pool owner assistance. It installs onto in-ground pool edges, using a standard garden hose that turns on automatically to fill your pool as water levels decrease. A float mechanism drops as your pool water drops, alerting the Pool Sentry to refill your pool's water, preventing the pool pump from running dry to help guard the equipment.

Ideal when away from your pool for extended periods of time, the Pool Sentry does not require permanent installation and is fully portable for convenience. For best results, have a low flow of water coming out of the garden hose. The Pool Sentry includes the water leveler body, fill tube, lid, float and hardware for installation. Reinforced hose and gravel sold separately.
