Where This Part Is Used

In typical pool and spa piping strategies, this manifold sits downstream of the pump or filtration loop to distribute flow across multiple returns or jets. It is commonly found in skimmer assemblies and return lines, as well as in jet body configurations where multiple outlets are required from a single source. The 1-Inch Slip connections simplify integration with standard PVC piping, while the 3/8-Inch Barb outlets feed separate hose runs to several components. This flow-thru design supports flexible routing and helps maintain balanced flow in multi-point circulatory systems. It is a practical solution for compact installations where centralized distribution improves system organization and serviceability.
