Abstract
A flush toilet stool includes a toilet bowl and a trap drainage passage connected to the toilet bowl. The toilet bowl has a water jet hole defined in a bottom region thereof and opening toward the trap drainage passage. A pressurizing unit such as a water pump is coupled to the water jet hole for drawing water under lower pressure directly from an external water supply and expelling the water under higher pressure through the water jet hole toward the trap drainage passage to develop a siphon flow to discharge sewage from the toilet bowl through the trap drainage passage.
