Abstract: An anti-siphon drain conduit. First and second cylindrical tubular portions with a U-shaped tubular portion interposed therebetween, and communicating with, the first and second cylindrical tubular portions. A drain passage extends through the conjoined tubular portions. A siphon break passage communicates with the drain passage at approximately the intersection of one of the cylindrical tubular portion and the U-shaped portion. A flap valve is formed integrally with at least one of the tubular portions for closing the siphon break passage upon the presence of liquid flowing through the drain passage. A bleeder cap is fitted to the siphon break passage. The bleeder cap has a dome portion penetrated by an aperture and an accordion portion. The bleeder cap serves freely to admit atmospheric pressure therethrough while tending to restrict any liquid that inadvertently enters the siphon break from exiting the siphon passage into atmosphere.

Abstract: A universal adaptor (10) to facilitate the connection, and retention, of a drain hose (12) with the standpipe of a household sanitary system. One end portion (11) of the drain hose (12) has an inlet cuff (15) adapted to be secured to the discharge tube (16) of a household appliance (18). The universal adaptor (10) is presented from the other end portion (11) of the drain hose (12). The universal adaptor (10) has a generally cylindrical body portion (20) which terminates in oppositely disposed proximal and distal ends (23 and 28, respectively). A passageway (21) extends axially through the body portion (20) and opens through the oppositely located proximal and distal ends (23 and 28). The proximal end (23) is adapted to be secured to the drain hose (12). The body portion (20) also has outer surfaces (25 and 26). A plurality of flexible, frustro-conical fins (30) project conically outwardly from the outer surfaces (25 and 26). The fins (30) have progressively stepped outer diameters (D.sub.A through D.sub.
