ABSTRACT:
A drain trap has a housing in the form of a four-sided outer vessel with a closed bottom and with a lateral outlet extending from one of its sides, this housing receiving an insert which forms a closed-bottom inner vessel of downwardly converging frustopyramidal shape spacedly surrounded on three sides by a skirt depending from the top of the insert and defining with three apertured walls of the inner vessel a downwardly open chamber communicating with a space beneath that vessel. The fourth side of the inner vessel is solid and spacedly confronts a partition which rises from the bottom of the outer vessel and has an overflow edge across which incoming liquid from the aforementioned chamber may reach the lateral outlet.
