Abstract: A trap seal protection device may provide an evaporation barrier for a drain and reduce odors and gases emitting from the drain. The trap seal protection device includes a housing including a flange engaging a radial surface of a drain assembly to support the housing relative to the drain assembly, a gasket coupled to the housing, the gasket having an outer diameter engaging an inner diameter of the drain assembly, a seal member positioned within the housing and selectively forming a seal against the housing. The seal member is movable to permit fluid flow through the trap seal protection device, wherein an axial distance between the flange and the seal member is greater than the outer diameter of the gasket.
