The Waterway 672-4250 4-port manifold is designed for compatible plumbing applications using a 2 inch spigot connection, a 2 inch slip connection, and four 1/2 inch socket branch ports. A manifold like this is useful where the main plumbing line must integrate flexibly into the surrounding layout while also feeding several smaller rigid branches.The four 1/2 inch socket outlets make this Waterway fitting especially practical for hard-pipe distribution systems rather than hose-based layouts. Its mixed spigot and slip main-line format also gives the installer more freedom when matching the manifold to an existing plumbing run.For compatible pool and spa plumbing, this Waterway manifold is a practical choice when four 1/2 inch rigid branch outlets are needed from a 2 inch main body with mixed-end compatibility.
