The Rola-Chem Pool Sentry M-3000 is a highly efficient, portable automatic water leveler designed to maintain the ideal pool water line without the need for permanent plumbing installations. Operating entirely on mechanical water pressure like a household toilet float valve, this heavy-duty plastic unit sits securely on your pool deck edge, anchored by an internal ballast bag you fill with rocks or pea gravel. Once connected to a standard outdoor faucet via a high-pressure, reinforced garden hose, it continuously monitors your pool, spa, or pond, automatically opening the valve to add water when levels drop from evaporation or splashing, and snapping shut once the target height is reached. Capable of maintaining water levels ranging from two to eight inches below the pool deck, it effectively prevents skimming filtration system failure and costly pump burnout during hot summer months or long periods away from home.
