Waterway D.E. Manifold Assembly With Air Relief Assembly (550-4200) fuses and in-line spa filter systemsThe Waterway 550 4200 manifold assembly with air relief assembly is designed for compatible D. E. filter applications that require both internal manifold support and air management at the filter. This combined assembly is especially useful because it brings together two important functional elements in one service oriented replacement part. When internal manifold components wear out or the air relief system is no longer operating correctly, replacing
