Watts-FSRO20 Flexwave Steel Tank for RO Storage, 16" x 29", 20 Gallon Capacity, 1"NPT
Watts FSRO20 Flexwave 20-Gallon Steel RO Storage Tank
The Watts FSRO20 Flexwave is engineered for commercial and high-volume residential RO systems where larger pressure differentials and storage capacity are critical. Its patented oversize diaphragm design delivers 20 to 30 percent more usable water than conventional tanks, while the cold-rolled steel construction with electrostatic polyurethane coating ensures long-term durability in demanding environments.
Built for High-Demand RO Systems
Patented Flexwave Design
Oversize butyl diaphragm increases usable water capacity by 20-30% compared to standard pressure tanks
Industrial-Grade Construction
Cold-rolled steel with precision welding, primer coat, and electrostatic polyurethane finish for corrosion resistance
Stainless Steel Connection
1" NPT all stainless steel water connection prevents corrosion and contamination at the tank interface
High-Pressure Rated
Maximum working pressure of 125 PSI, tested and certified for air-tight performance in commercial applications
20-Gallon Capacity
Generous storage volume in a 16" diameter by 29" height footprint for institutional and high-use installations
100% Butyl Diaphragm
Food-grade butyl rubber membrane isolates stored water from compressed air for pure, uncontaminated delivery
Designed for Commercial and High-Volume RO Systems
The Watts FSRO20 is ideal for reverse osmosis systems requiring extended storage capacity and rapid delivery rates. Suitable for restaurants, coffee shops, laboratories, light industrial applications, and large residential systems with 75 GPD or greater RO membranes. The 1" NPT connection accommodates high-flow plumbing and works with Watts Premier, APEC, iSpring, and other professional-grade RO systems. Tank dimensions are 16" diameter x 29" height; allow clearance for top-mounted connection and pressure valve access.
Watts has been engineering reliable water treatment solutions for residential and commercial markets for over 145 years, and every Flexwave tank is factory-tested for air-tight integrity before shipping.
