## Abstract

A hot beverage maker manifold assembly is disclosed integrating components into the manifold body minimizing leak paths and creating efficient overall drain and vent performance of the aircraft hot beverage maker. A top vent valve is integrated into the manifold body for complete venting and draining performance in the manifold assembly as well as in an associated hot water tank and tank lines. An incorporated flow regulator housing within the manifold body at a tea line exit fitting limits the number of downstream leak paths and complexity. An integrated lower manifold clean out port allows for efficient bi-directional service of the manifold and efficient descaling and flushing.
