This 4-Valve 1-Tank Plumbing Manifold Kit includes PVC piping, heavy-duty Cepex butterfly valves, and complete linkage sets. It is specifically designed to fit the Jandy SFHT4296 horizontal filter. Manifolds centralize piping and valve functions, allowing multiple filters to operate in parallel with balanced hydraulic performance. They enable synchronized functions such as filtration, rinsing, and backwashing, including the ability to backwash one or both filters while maintaining system operation. This coordinated control reduces the need for external plumbing and provides a single control point for operators.
