The Waterco 1-1/2 inch 6-position Micron top mount multiport valve is designed for compatible filter systems that require a top-mounted valve capable of handling multiple operating modes. A multiport valve is useful because it centralizes several important functions such as filtering, backwashing, and related water-routing modes into one control point.This replacement is especially useful when the original valve body has worn out, internal switching has become unreliable, or the system needs the correct top-mount configuration restored. The 6-position format makes it a practical choice for systems that depend on versatile, organized control of filter operation.The WC228042 is a strong service solution when a compatible Micron filter setup needs the correct 1-1/2 inch top-mount multiport valve to restore full functionality.
