Abstract: A cartridge apparatus for use with a urinal (e.g., a waterless urinal) is configured to be received at least partially within a cartridge housing associated with the urinal bowl thereof. The cartridge apparatus includes a cartridge top member having at least one opening configured to allow urine in a urinal bowl to pass into the cartridge apparatus and a fluidless cartridge trap connected to the cartridge top member that is normally in a closed state to prevent gases (e.g., sewer gases or other odors) from exiting from a cartridge housing and that is in an open state to allow urine to pass therethrough when urine is received in the cartridge apparatus through the cartridge top member. A urinal apparatus with which the cartridge may be used may include a cleaning apparatus for use in disinfecting and/or deodorizing the urinal apparatus.

Abstract: A pressure assisted flush assembly for use with a toilet includes a compressed air assisted flush water tank that includes a plunger device. One or more plumbing lines are used to connect an incoming water line to the flush water tank and the flush water tank to a toilet bowl. At least one panel is used to enclose the flush water tank (e.g., mounted against a wall). The enclosure comprises an access door configured to allow access to the flush water tank and the access door is secured with a lock mechanism to prevent unauthorized access to the flush water tank. Further, for example, an accessible activator mechanism is configured to activate the plunger of the flush water tank. The assembly may be, for example, configured to retrofit a previously installed flush valve toilet.
