Abstract: A bypass valve assembly for directing fluid flow having at least one inlet and at least one outlet for fluid flow, the bypass valve assembly being attachable to a fluid treatment system. The bypass valve assembly also includes at least one bypass valve in the bypass valve assembly, the bypass valve having a service configuration and a bypass configuration wherein in the service configuration at least a portion of fluid entering the bypass valve assembly through the inlet is transmitted to the water treatment system and wherein in the bypass configuration fluid entering the bypass valve assembly is not transmitted to the fluid treatment system. At least one blending valve is operatively interconnected to the bypass valve assembly, wherein when the bypass valve is in the service configuration the blending valve allows a portion of fluid entering the inlet to be transmitted to the outlet without being transmitted to the fluid treatment system.

Abstract: A water treatment system for removing impurities from incoming feed water includes a manifold having a plurality of water treatment filter housings connected thereto. The filter housings are configured to accept a plurality of water treatment filter cartridges, which have, at one end, a filter housing cap fixedly attached thereto. The system manifold is also adaptable to be able to connect to peripheral accessories, filtration devices, and identical water treatment systems.
