Full Product Description +

The Rola-Chem Pool Sentry M-3000 is a portable, automatic water leveler designed to maintain proper water levels in pools, spas, and decorative ponds without constant supervision. This device automatically adds water when levels drop due to evaporation, splash-out, or normal use—helping protect equipment and ensure consistent circulation.

The Pool Sentry connects to a standard garden hose and uses an adjustable float mechanism to maintain a preset water level. When water drops below the set point, the unit opens to add water; once the correct level is restored, it shuts off automatically. This simple, mechanical design requires no electricity, plumbing modifications, or permanent installation.

Ideal for residential pool owners, vacation homes, and service professionals, the M-3000 offers a convenient solution for unattended water level control.


Why Automatic Water Leveling Matters

Maintaining proper water level is critical for system performance.

Why this matters:

  • Prevents pumps from running dry

  • Protects skimmers from air intake

  • Maintains proper circulation and filtration

  • Reduces manual water filling

  • Helps avoid costly equipment damage

Consistent water level management supports both safety and efficiency.


Designed for Pools, Spas & Ponds

The Pool Sentry M-3000 is designed for use in swimming pools, spas, and ornamental ponds. Its portable design allows it to be placed directly in the water and connected to a hose—making it ideal for both temporary and long-term use.

The adjustable float allows users to fine-tune the desired water level based on pool design and skimmer height.


Simple, Mechanical & Reliable Design

This water leveler operates using a mechanical float valve, eliminating the need for electricity, sensors, or programming. Its durable construction is built to withstand continuous water exposure and outdoor conditions.

The Pool Sentry’s straightforward design makes it a dependable solution for unattended water level maintenance.


Installation & Use Notes

For best results:

  • Place the Pool Sentry on the pool step or ledge

  • Attach a standard garden hose to the unit

  • Adjust the float to the desired water level

  • Turn on the water supply

  • Periodically check operation to ensure proper function

For added safety, many users install a hose timer or pressure regulator.
