What Makes Up a RO Re-Pressurization System?
The RO Re-Pressurization System stores treated water produced by a reverse osmosis system and delivers it back to the home or building at usable pressure. Each component works together to manage stored RO water and provide pressurized water when it is needed.
High-Level Float
Monitors the water level inside the storage tank and communicates with the RO control board when the tank reaches its full level, signaling the RO system to stop producing water.
Mechanical Overflow
Provides an additional path for water to exit the tank in the event of an overfill condition.
Pressure Pump
Draws from stored water and delivers consistent pressure and flow to the home or building.
Water Storage Tank
Stores collected well water so household demand is separated from the well’s immediate production rate.
RO Water Storage & Level Control
Treated water from the reverse osmosis system flows into the storage tank, building a reserve that can be used throughout the home or building. The tank fills as the RO system produces water, allowing treated water to be stored and ready for periods of higher demand.
Automatic High-Level Control
A high-level float monitors the water level inside the storage tank and communicates directly with the RO system’s control board. When the tank reaches its full level, the float signals the RO system to stop producing water.
As stored water is used and the tank level drops, the RO system can resume production and begin replenishing the stored water supply.

Pump Options for Your Water Demand
RO Re-Pressurization systems can be configured with different pressure pumps based on the required flow, pressure, electrical supply, application, and installation layout.
Bladder Tank Requirements
Installation Note: For best performance and to help prevent rapid pump cycling, install a bladder tank on the discharge side of the pump. DAB recommends sizing the bladder tank based on your pump’s normal peak flow:
- 2-gallon bladder tank – E.SYBOX Mini 3 (approximately 10 GPM)
- 4-gallon bladder tank – E.SYBOX, DTRON 2, and DIVER (approximately 20 GPM)
- 10-gallon bladder tank – E.SYBOX MAX (approximately 50 GPM)
With a Well Manager® system, the existing pressure tank can often be reinstalled after the system to serve as the bladder tank.
