It helps resolve common whole-home humidifier issues such as no water flow, uneven humidity, dry skin, and static by delivering smooth, reliable operation season after season. The included brass compression hardware supports a quick, secure, leak-resistant installation on copper or plastic tubing—slide the compression nut and ferrule onto the tubing, insert the brass sleeve, then tighten to the valve threads; an integrated screen helps reduce debris entering the system.
