RO Re-Pressurization System

The RO Re-Pressurization System installs after your whole-house RO filtration system. As the RO system produces filtered water, it fills the Re-Pressurization tank. A float inside the tank monitors water level and signals the RO system when more filtered water is needed.

The system then uses its built-in vfd pressure pump to deliver stored, filtered water to the home at consistent pressure—independent of the RO system’s production rate.

Filtered water enters the tank at a fixed rate based on the RO system’s production capacity. The float system automatically starts and stops filling to maintain proper storage levels.

This ensures filtered water is always available in reserve and ready to be pressurized and delivered on demand—even during periods of high household use.

Because the system stores filtered water in advance, it provides a reliable reserve for both household use and RO system backwash cycles, which often require higher flow rates than the source or RO system can produce on demand.

Backwash water is supplied directly from the storage tank instead of pulling immediately from the incoming water source or forcing the RO system to keep up in real time. This prevents strain on the water source, avoids interruptions in household supply, and allows the RO system to operate at its intended production rate.

By storing and re-pressurizing filtered water, the system ensures consistent pressure, reliable supply, and smooth filtration system operation—even during backwash cycles or periods of high demand.
