Abstract:
A filtration assembly includes a feed water line and a permeate line. A shut-off valve is coupled between the permeate line and the feed water line and operative to open the feed line when the faucet is opened based on a pressure differential between the feed line and the permeate line. An energy storage member is located within the permeate line and configured to compress and then expand after the faucet is closed causing the shut-off valve to fully close.
