The Valve-in-Head Whole House Water Filtration System features a valve built into the housing head. Replacement filter cartridges can be replaced without shutting off the main water line. Simply turn the valve in the head to the off position. The clear filter housing lets you see the filter to visually monitor filter life and condition. Each time you change the filters it is recommended to sanitize the housing and replace and lube the O-ring to prevent water leaks.
