In the case of indirect or momentum siphonage, the circulation of water past the entrance to a component drain in the drain removes air from the fixture drain. This lowers the air pressure in the fixture drain, and the whole assembly serves as an aspirator. (and reveal plumbing configurations that would permit this kind of siphonage to occur.).

The atmospheric pressure requires the trap seal up the pipeline into the fixture. If the pressure is fantastic enough, the seal is blown out of the fixture totally. and illustrate the capacity for this type of problem. Big water flow past the vent can aspirate the water from the trap, while water circulation approaching the trap can blow the water out of the trap.


The system venting system is frequently used in home buildings.
