Watts-FSRO80 Flexwave Steel Tank for RO Storage, 26"x 44.5", 85 Gallon Capacity, 1 1/4"NPT

The Watts FSRO80 Flexwave is an 85-gallon steel pressure tank engineered for commercial and high-demand reverse osmosis systems that require substantial treated water storage and consistent delivery pressure. Its patented oversize diaphragm design stores 20-30% more water than conventional tanks of similar size, delivering reliable performance in applications where pressure differential and volume matter.

COMPATIBILITY & APPLICATIONS

Ideal Use Cases

The Watts FSRO80 is designed for commercial reverse osmosis systems, restaurants, offices, light industrial applications, and residential installations where water demand exceeds typical household use. The 1 1/4" NPT connection accommodates higher flow rates than standard residential tanks. Best suited for RO accumulator systems requiring large pressure differentials and consistent delivery pressure during peak draw periods. The 26-inch diameter footprint allows installation in mechanical rooms and equipment areas where vertical clearance is available.

💧 Pre-charge the tank to match your RO system's shut-off pressure minus 5-7 PSI before installation. Proper pre-charge ensures maximum usable capacity and extends diaphragm life in high-cycle commercial environments.
