Abstract
A dishwasher spray arm hub assembly includes a hub having a first central bore extending therethrough and a conduit feed extending therefrom. The conduit feed is in flow communication with the central bore and a venturi insert is disposed in the hub central bore. The venturi insert also includes a second central bore extending therethrough. The first bore and the second bore together form a fluid bypass channel in flow communication with the conduit feed. Therefore, a lower spray arm assembly and a spray arm conduit for upper spray arm assemblies may be simultaneously fed through the hub assembly.
