Eliminates the need to drain the tank during normal filter changes (tank should always be drained after the membrane is changed). This easy to install valve attaches to the top of the storage tank. It is a 3/8 inch John Guest quick connect (push in) fitting for use with the WP-5 and WP-4V models.
Works with all threaded 1/4 inch Male threads and 3/8 inch plastic water lines.
