Unlike pressure assist toilets, which can be noisy and are made with more complicated moving parts, E-Max is a simple and quiet solution for effectively flushing 1.28 gallons. Utilizing the same proven engineering as our legendary 1.6 GPF G-Max flushing system, the 1.28 GPF E-Max reinforces TOTO's performance reputation while offering an additional water savings of 20%. E-Max features:
Wide 3" flush valve provides a quick, consistent and powerful flush.
Large 2-1/8" trapway is glazed to optimize waste passage.
Pilot-operated fill valve ensures quiet operation and a clean shutoff at any water pressure.
Extra-large siphon jet works in conjunction with the large glazed trapway; the siphon jet pulls away waste with incredible force.
