ABSTRACT:
The cap to a reverse osmosis (R.O.) system membrane cartridge housing integrates both (i) a system automatic shut-off valve, and (ii) an improved check valve of such enlarged area and low pressure drop as typically gains 2-4 gallons per day in purified water output. The housing both reduces, typically from seven ports to five ports, and simplifies with hand-tightened quick fittings, the plumbing requirements of the R.O system. The housing fits a new and larger, typically 100+ gallon per hour, high-flow-rate R.O. membrane cartridge as well as myriad universal standard cartridges. A pressure gauge is optionally integrated.
