ABSTRACT:
A pneumatic assisted flush system for toilets having a raised water storage tank and a flush valve discharging into a toilet bowl, characterized by a primary air seal at the rim of the toilet bowl and a secondary air seal established in a flush passage during flushing, whereby the toilet bowl is converted into a closed chamber for the entrapment of air compressed by the discharge of flush water, thereby depressing debris laden water in the toilet bowl in order to initiate syphoning through a flush pipe and into a sewer.
