ABSTRACT:
A reverse osmosis water purifying device is provided with a flush water restrictor which serves to provide a suitable back pressure on the reverse osmosis membrane in order to affect the purification process. The device is designed for attachment to any source of pressurized water. The restrictor device consists of a capillary tube sized to provide a suitable ratio of flush water to purified water. A ball-type check valve surrounds the capillary tube at its point of exit and the ball valve may be dislodged in order to flush the membrane. The core of the membrane assembly is filled with activated charcoal in order to provide for a more efficient and complete purification.
