Pennsylvania Statutes Title 53 P.S. Municipal and Quasi-Municipal Corporations § 4632. Setting and kinds of traps

All traps must be well supported, and set true with respect to their water levels.

All bath-tubs shall be supplied with drum, “P” or running traps with clean-out trap-screw on floor or ceiling line.  In case where an additional fixture is required in a building, and it is impossible to get revent pipe for the trap, the board or bureau of health  1 shall designate the kind of trap to be used.  This shall not be construed to allow traps without revents, in new buildings, or any one particular kind of an antisyphon trap.  No trap, which depends for its seal upon the action of movable parts or submerged interior partitions, shall be allowed.
