Rola‑Chem Pool Sentry Water Level Control | M‑3000 The Pool Sentry M‑3000 is a portable, automatic water-level maintenance device designed to protect pools, spas, or ponds from low-water conditions. This unit uses a weighted assembly and float valve system to turn your water supply on and off—keeping your water level constant and preventing pump burnout, without requiring permanent installation. Includes: Water leveler body with integrated float valve Fill tube assembly Top lid and base hardware Internal bag for pea gravel or rock ballast (not included Gravel) Key Features: Automatically maintains pool water level as evaporation occurs No permanent installation—simply attach a garden hose Adjustable float allows precise level setting Portable design—ideal for rentals, vacation homes, or acid-washes Rated to 200 psi working pressure and 750 psi burst strength when used with reinforced hose Protects pool pump by ensuring adequate water supply Technical Specifications: Manufacturer: Rola‑Chem / Paradise Industries Model / SKU: M‑3000 Application: Residential pools, spas, or ponds Operation: Float-actuated control of water supply Ballast: User-filled bag with gravel or rocks Pressure Rating: 200 psi working / 750 psi burst (with reinforced hose) Shipping Weight: ≈ 3.5 lb Operational Range: 2″ to 8″ below pool deck edge 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.
