RO Storage Tanks

RO Storage Tank Products and Fitment Basics

RO storage tanks are pre-pressurized vessels designed to hold purified water and deliver it with consistent pressure. Common choices include 2 to 6-gallon class tanks for under-sink setups, plus mid and large tanks around 9, 14, 20, and even 44 gallons for light commercial, ice makers, or higher-demand homes. Many models use durable steel construction, with stainless steel options available for added corrosion resistance and long service life. You will also see different port options such as 1/4 inch for typical RO lines, 3/4 inch for higher flow, and larger ports on high-capacity tanks. Usable draw-down volume differs from the listed size, so checking specs helps you pick a tank that meets daily needs. Matching capacity, port size, and available cabinet or utility-room space helps the system cycle correctly and keeps your water pressure feeling reliable.
