ABSTRACT:
An apparatus and method whereby after a reverse-osmosis water purifier system has been shut down, the first quantity of water, which emanates from the reverse-osmosis filter, does not flow through the pure water storage tank but instead to the drain. Therefore, the water in the reverse-osmosis filter, and which has become contaminated as the result of standing in the filter so that a substantial amount of osmosis can occur, does not contaminate the pure water in the storage tank or system but instead is discarded.
