Abstract: An in-line P-trap chlorinator that ensures water contact with a water-leachable algicide and/or antibacterial tablet while water is flowing through the P-trap, and after the flow of water has stopped. The in-line P-trap chlorinator is inserted in a condensation drain line of an air-conditioning or refrigerating unit to prevent formation of growth from bacteria or algae, which would plug the line, and/or to destroy any such growth already in the line. The inlet to the P-trap chlorinator is above the outlet, to prevent back-migration of harmful and/or corrosive gases, vapors, and/or liquids/mixtures/solutions. The P-trap chlorinator performs and combines the functions of a P-trap and a chlorinator. No additional P-trap is required.

Abstract: A disposable solid waste detainment plumbing trap. The trap has a container for collecting water and solid waste discharged from a sink through a line threadably connected to an inlet of the container, and for discharging water through an outlet threadably connected to a waste line. It has a lid which seals the container, and a valve for venting either air or water from the container, to relieve the pressure of air trapped in the container. Using this disposable trap, solid waste from a sink can be quickly and easily collected and disposed of without spilling of or contact with water or the solid waste.

Abstract: A solid-sediment retainment plumbing trap devised primarily for a sink from which substantial amounts of solid material are discharged; e.g., eyeglass manufacture and dental plastic grinders. The plumbing trap is connected to the sink, and collects sediment in a bottle having a fill line. When sediment collecting in the bottle reaches the fill line, the bottle is exchanged for a similar bottle, and the plumbing trap is once again in service. Because the bottle is connected to the rest of the trap by threads, bottle exchange is rapid and easy.
