Abstract
A water-conserving toilet is disclosed and includes a bowl for receiving waste and a waste outlet extending laterally from the bowl and defining a first, shallow trap arranged so that a relatively shallow body of liquid is normally retained in the bottom of the bowl for preventing gaseous flow through the trap. A flush system is provided and is arranged, when operated, to deliver a charge of flushing liquid into the bowl in a direction to cause said body of liquid to be discharged through said outlet. An enlarged chamber communicates with said bowl outlet for receiving waste from the bowl. An outlet extends outwardly from the chamber and is adapted for connection to a sewer inlet. The chamber outlet defines a second trap of substantial height capable of preventing reverse flow of sewer gas into the chamber in use. The toilet also includes means communicating with the chamber and adapted to relieve increase in gas pressure caused by liquid entering the chamber from the bowl, whereby back pressure resistance to flushing of liquid from the bowl is reduced.
