Abstract
An in-the-wall plumbing trap having integral connections for waste and vent lines wherein in the vent connection is located on the top of the trap housing and the waste connection on the bottom thereof. A substantially vertical wall formed by an overflow member separates the housing interior into two chambers with a liquid seal chamber located beneath a waste intake line and a separation chamber disposed on the other side of the overflow member. Effluent waste entering the liquid seal chamber builds up until reaching the top of the overflow member where it then spills over into the separation chamber and any gases contained therein rise to the top of the housing and escape through the vent line as the fluid flows to the bottom of the separation chamber and exits through the drain pipe.
Claims11
An in-the wall plumbing trap with integral waste and vent lines comprising:
- a) a housing that is substantially rectangular in cross section having a top plate, a bottom plate, a front plate, a rear plate, a first sidewall, a second sidewall and a substantially hollow interior;
- b) an overflow member within said interior of said housing and sealed engagement with said front plate, said rear plate and said second sidewall where it traverses medially therefrom to a central portion of said housing interior and then extends upwards prior to terminating well short of said top plate thereby defining two distinct chambers in communication with one another through the open passage formed between the top edge of said overflow member and said top plate with the chamber defined by said overflow member and said second sidewall being the liquid seal chamber and the chamber defined by said overflow member and said first sidewall being the separation chamber;
- c) a cylindrical vent pipe coupling exteriorly disposed on said top plate and extending perpendicularly therefrom having a central cavity to provide passage therethrough from said housing interior;
- d) a cylindrical waste line coupling exteriorly disposed on said bottom plate and extending perpendicularly therefrom having a central cavity to provide passage therethrough from said housing interior;
- e) a cylindrical wall flange assembly having a body exteriorly disposed on an upper portion of said front plate, offset to a region residing above said liquid seal chamber and extending perpendicularly therefrom having a central cavity forming an inlet pipe opening to provide passage therethrough to said housing interior, the distal end of said body wall flares outward and then forms a cylindrical finishing flange having a greater internal circumference than the internal circumference of said body;
- and
- f) a removable flexible insert fabricated of a resilient impermeable material and comprising a cylindrical sealing head with an exterior circumference slightly less the interior circumference of said body of said wall flange assembly, said sealing head having a first end and a second end with said first end having a substantially flat sealing face extending peripherally therefrom with the exterior circumference thereof greater than the interior circumference of said finishing flange, at least one sealing flange extends peripherally from a central portion of said sealing head with an exterior circumference greater than the interior circumference of said body of said wall flange, a discharge tube projects from said second end of said sealing head at a substantially 90 degree angle.
