US Patent 9731984 Reverse osmosis systems with built in pressure regulation

Systems for counter top and under the counter use having a self contained reverse osmosis filter system having a manifold assemble under which parts of the self contained reverse osmosis filter system are attached, and a raw water pressure regulator also attached under the manifold assembly, the raw water pressure regulator having an inlet for coupling to a source of raw water and an outlet coupled to the inlet for the self contained reverse osmosis filter system, whereby the ratio of product water to waste water may be maximized under normal operating conditions without clogging the self contained reverse osmosis filter system if the pressure of the source of raw water is high.
