Abstract
A contamination unit for isolating a building from contamination of a sewer is disclosed. The contamination unit includes a housing with an inlet and an outlet, a trap assembly, and a fluid trigger. The inlet is in fluid communication with a fluid source, plumbing equipment, and/or condensating equipment to receive fluid. The housing has a reservoir to collect the fluid therein and to define a reservoir portion of a contamination barrier about the outlet. The trap assembly includes a trap conduit between the outlet and the sewer that is shaped to collect the fluid therein and define a trap portion of the contamination barrier. The fluid trigger is positionable about the housing to selectively release the fluid through the inlet and into the reservoir of the housing whereby the fluid in the contamination barrier is maintained to prevent the contamination from passing from the sewer into the building.
