ABSTRACT:
A sanitary syphon gas trap particularly adapted for use in association with squat-type water closets, which are installed at floor grade level, which trap has an inlet arm and an outlet arm of circular cross-section, and an angularly disposed seal arm in rebent relationship to said inlet arm intermediate the inlet and outlet. The seal arm has an arcuate non-circular cross-section whose area is less than the flow area of said inlet arm and whose juncture with the outlet arm defines a flow-fall which is out of the main stream of the flow path between the seal arm and the outlet arm. A downwardly directed water jet from the water closet initiates a Venturi effect of high velocity flow in the seal arm for waste discharge.
