ABSTRACT:
A trap for a drain has a housing with a sidewall forming a lateral exit port above its bottom. A tubular insert fitted to that sidewall forms a conduit with a bottom inlet beneath the level of the exit port and a side outlet registering with this port. The outlet is framed, along about a lower third of its periphery, by a generally spoon- or trough-shaped tongue extending inwardly therefrom while rising toward but terminating short of the horizontal midplane of the outlet; a ring-segmental clearance remaining between this tongue and the peripheral conduit wall has a cross-sectional area equal to or slightly larger than that of the outlet.
