Abstract

A high efficiency toilet configuration is provided, including a water tank. The tank includes a supply line, a mechanical valve controlling a flow of water from the line into the tank, and walls and a base. The tank includes a through-hole in the base channeling water out of the water tank and a tank outlet hole including a housing extending through the through-hole. The tank includes an outlet valve configured for selectively prohibiting water from flowing through the tank outlet hole and permitting water through the tank outlet hole during a flush event. The tank includes a water column vessel disposed around the outlet hole and configured for separating water in the water tank between water outside of the vessel and a channel of water contained over the outlet hole. The configuration includes a toilet base including a bowl and a plenum for channeling the water to the bowl.
