ABSTRACT:
A trap incorporating an access fitting and of the type that may be designed into a P-trap, or S-trap configuration, the trap including an inlet segment and an outlet segment, both being integrally joined together, and a lower arcuate portion forming the access fitting that intervenes and joins together for communication the interior channel through the trap, the interior channel being of a fixed diameter throughout its extent, and forming a continuous smooth wall interior surface along the entire length of the trap. A flange projects integrally from both the combined upper inlet and outlet integral sections, while a corresponding and registering flange extends from the arcuate portion for arrangement in alignment with the upper segment flange to facilitate assembly of the trap. The plane of separation between the upper segments and the lower arcuate portion or fitting is provided between the weir formed by the interior surface of the channel formed between the upper inlet and outlet segments, and that location downwardly therefrom where the fixed diameter of the channel commences to reduce in dimension below its full diameter due to its lower disposition within the arcuating portion of the access fitting of the trap.
