Abstract

A one-piece manifold (110) for a reverse osmosis system includes a filter (112) configured to receive water from a water port (154) and a membrane (116) configured to receive filtered water via a first conduit. The membrane is also configured to send permeate water to a reverse osmosis tank (156). The manifold also includes a flow restrictor (117) configured to receive concentrate water from the membrane via a second conduit and to pass the concentrate water to a drain port.
