A flush toilet comprises a bowl, a water tank, a drainpipe in communication with the basin of the bowl and a septic tank, and a loop connected between the bowl and the drainpipe to enable parts of water and air in the drainpipe to flow into the bowl basin at such time when the toilet is flushed, thereby enabling the waste matter to fall rapidly by its own weight into the septic tank.
