Product Description

Reverse osmosis systems used with an auto shut off valve require a check
valve to prevent backflow. This allows pressure to build up so the auto
shut off can activate and shut the system off. Systems that continually run
water down the drain may be missing the check valve, and systems that
intermittently turn on without any water use may indicate a worn check
valve
