      SIPHON-JET

    • D. 

      WASH-DOWN

  • 6. 
    Water enters through diagonal punching around the rim of the bowl, creating a vortex that draws the water down into the rear trap with a swirling action that scours the walls of the bowl. Water strikes two parallel ridges and folds over forming a jet, producing siphonic action. A large water surface provides a very efficient and clean process, and the flushing is extremely quiet. This model is mostly of one-piece construction with a low profile. Expensive.
    • A. 

      SIPHON-VORTEX

    • B. 

      SIPHON-JET

    • C.

    • D. 

      WASH-DOWN

  • 7. 
    Water enters through an open rim, as though a bucket of water were dumped into the bowl, filling the front trapway and creating siphon action. This model provides quick removal of water with minimum water rise. Small water surface makes the model more vulnerable to soiling and clogging. This is the least efficient and most noisy type but lowest in cost.

      STACK VENT

    • C. 

      RELIEF VENT

    • D. 

      DRY VENT

  • 14. 
    Strong flushing action is created by a jet of water directed into the rim and jet. The force of the jet draws the bowl contents into the rear trap. It doesn't use siphonic action but relies on the driving force of jet action. At flush valve 25 psi is needed with 1.5-in. inlet spud. Large water surface and large trapway size make this model efficient and suitable for commercial use. Flushing is very noisy. Expensive.

    Water enters through rim punchings and through a jet that fills the rear trapway completely, creating a siphon action and resulting in quick withdrawal of water from the bowl. A water jet is located at the inlet of the trapway. Most of the bowl surface is covered with water. This model is efficient but moderately noisy. Its cost is reasonably low.
