    A steel tank is located inside the china tank. Uses pressure from the water supply system. A 1.5 in. water supply line provides 25 psi pressure, compressing trapped air in the tank. When flushed the compressed air forces the water out. The bowl is designed to accept the torrent of water. The crest of the surging water empties the bowl through the enlarged trap. Large water surface makes this model efficient. Design features make it suitable for residential use. Flushing is very noisy. Low water usage (1.5 gpf) helps conserve water. Expensive.
