The Waterway 672-4190 4-port flow-thru manifold is designed for compatible plumbing applications using a 3/4 inch slip branch connection, a 1-1/2 inch slip connection, and a 1-1/2 inch spigot connection. A flow-through manifold like this is useful where the main line must continue through the assembly while still supporting multiple outlet paths in a compact plumbing arrangement.

This mixed-end configuration makes the fitting especially practical for retrofit and service work where the surrounding plumbing may not all use the same connection style. Choosing the correct Waterway manifold helps maintain compatibility while keeping the distribution layout more organized.

For compatible multi-line plumbing systems, this Waterway manifold is a practical solution when a flow-through 1-1/2 inch main body with additional branch capability is needed.

  • 1-1/2 inch slip x 1-1/2 inch spigot main configuration
  • Supports additional branch distribution from the manifold body
