Abstract
The disclosed technology includes low flush toilet systems and methods of using low flush toilet systems. In one implementation, a low flush toilet system includes a first (or passive) tank, the first tank configured to preload a toilet rim, and a second (or pressurized) tank, the second tank including an internal air bladder, the internal air bladder configured to compress when exposed to water pressure from a supply line and configured to expand when a flush valve releases pushing water out of the second tank at a high flow rate and into a toilet for flushing. In some implementations, water flows from the pressurized tank at approximately 0.7-1.0 gallons per flush.
