US 12,687,001 B2 · Trap seal protection device

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.

Dependent claims

A trap seal protection device for a drain assembly having a drain body, the trap seal protection device comprising:

a housing including a flange configured to engage a surface of the drain assembly to support the housing relative to the drain assembly;
a gasket supported by the housing, the gasket having an outer diameter and configured to engage an inner surface of the drain body;
and
a seal member supported by the housing and selectively sealing a fluid passageway, the seal member being selectively movable between an open configuration wherein the seal member permits fluid to flow past the seal member and a closed configuration wherein the seal member blocks fluid flow past the seal member, an axial distance between the flange and an upper end of the seal member in the closed configuration being greater than the outer diameter of the gasket.
