GWS reverse osmosis tanks are the industry leaders in purified water storage. Constructed with highest-quality FDA-compliant materials, the tanks feature an assembled water storage chamber made with virgin polypropylene liner, high-quality butyl diaphragm, and a patented stainless steel water connection.

Each diaphragm is subsequently cured to eliminate any elements that could impart odor or taste. This ensures zero secondary contamination and keeps the water pure and clean in the RO system.
