Abstract
A reverse osmosis system having a tank for storing purified water includes a valve in the pipe which introduces feed water into a module containing a semipermeable membrane and which produces the purified water. The valve shuts off or turns on introduction of feed water into the module in response to the weight of purified water in the storage tank.
