A tube assembly is positioned within the housing through the drain aperture and connects to the housing, connecting the delay mechanism to the funnel. When in use, brewed beverage is formed in the funnel. Brewed beverage flows through the filter assembly and rises in the housing at the same rate as does brewed beverage within the funnel.
