ABSTRACT:
A sink trap having a novel clean out arrangement. The clean out arrangement comprises an upwardly extending branch that projects obliquely from the long vertical leg of the J-bend portion of a sink trap. The clean out branch has a relatively large diameter, being of substantially the same diameter as the J-bend itself. At its upper end the clean out branch has an easily removable, sealing closure. With the arrangement provided, the clean out opening is in a readily accessible location and the closure can be removed without tools to permit the trap to be cleaned.
