  • Patent number: 6845527
    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.

  • Patent number: 6823540
    Abstract: A device for blocking or impeding the flow of water through the overflow drain of a bathtub of the type including a wall, an overflow drain opening in the wall, and a generally circular cover plate over the overflow drain opening, the cover plate having an annular skirt with at least one overflow opening in the annular skirt at the bottom of the cover plate. The device takes the form of a stopper including an arcuate surface configured so as to cover the overflow opening. The stopper is made of a material and is configured so as to be held in place, when water level in the bathtub is above the overflow opening, by water pressure or buoyancy only. As a result, the stopper, once held in place, falls away from the overflow opening when water level in the bathtub subsequently drops below the cover plate.

  • Patent number: 6425411
    Abstract: Improvements in retention of the oily liquid sealant (20) in a oil-sealed odor trap (10B-10M), for drain applications such as a waterless urinal or anti-evaporation floor drain, are accomplished by minimizing turbulence in the oil sealant, such as by making the liquid flow path (22A, 22B) substantially horizontal as a departure from conventional practice of substantially vertical flow and by positioning a barrier (40) above the oil sealant to prevent direct impingement of urine or other waste products onto the sealant. The trap is thus structured to realize the substantially horizontal liquid flow path and to locate the flow path immediately beneath the sealant layer or beneath a baffle portion (16B). The baffle portion may be sloped such that stray sealant droplets are encouraged to migrate upwardly to the upper surface of the flow path due to their buoyancy and, therefore, the stray droplets will be recaptured and returned to the main sealant layer.
