A plumbing drain trap treatment mixture is disclosed. The mixture is poured into a plumbing drain trap to form a layer of the mixture that floats on top of the water in the trap. The mixture layer forms a boundary to prevent evaporation of the water from the trap, thereby maintaining the water in the trap to prevent sewer gas infiltration and pest infiltration to the building. The anti-pest and antimicrobial properties of the mixture may serve to further prevent migration of pests from the sewage drain beyond the trap through the plumbing trap and into the building and/or to protect the barrier itself from microbial infestation. A method of use of a treatment for a plumbing drain trap is also disclosed.

Disclosed herein is a structural drain trap for preventing spread of pathogens between floors, which has an improved structure in which it includes a cover and an outer chamber that are easily coupled to and decoupled from each other and provides a drain line configured to have a double structure at inner and outer portions thereof. Therefore, it is possible to prevent pathogens such as Coronavirus as well as odors or pests from flowing backward as much as possible, and thus to prevent pathogens from spreading through the gap between the floors of buildings such as apartments.

A malodor reflux blocking unit using the cardiac valve principle, includes a space providing portion inserted into the drain pipe through the drain hole and configured to provide a drain space for the drainage, blocking portions which are, in a non-draining state, disposed to face each other and configured to block communication between the drain pipe and the drain space due to a water film phenomenon which occurs due to drainage water being present between the blocking portions, and intermediate portions configured to mediate connection between the blocking portions and the space providing portion.

Certain exemplary embodiments can provide a system, machine, device, and/or manufacture that is configured for operably releasing condensate received from a condensate-producing unit toward a drain without allowing a substantial quantity of gas to flow through the system, machine, device, and/or manufacture, those embodiments including a float and/or a housing.

A removable cartridge for a low or zero water urinal outlet comprises a body comprising a side wall including one or more locking projections projecting out from the wall. One or more resilient elements are provided in the wall and each resilient element includes one of the locking projections.

A toilet flange cap with cleaning basin is presented. The toilet flange cap with cleaning basin contains a cap body and a flange seal. The flange seal is connected adjacent to the cap body. The toilet flange cap with cleaning basin allows a user to plug and seal a flange aperture along a toilet flange insert, preventing sewage gas and airborne pathogens from emitting from the flange aperture.
