A sound attenuating drain stop for an orifice in an automotive floor pan has a resilient plug portion disposed in the orifice and a drainage bore extending axially therethrough, an annular groove for receiving the body panel so as to secure the plug portion thereto, and a compliant element completely obstructing the bore and selectively unobstructing cross-sectional areas of the bore in response to weight variation of fluid thereabove. The compliant element has a resilient, three-legged bridge member spanning the bore and deflectable under the weight of a first predetermined quantity of fluid to drain fluid above the element, and three pie-shaped flexible flaps defined by the bridge member and extending from an interior surface of the bore to the bridge member, the flexible flaps deflectable under the weight of a second predetermined quantity of water when the bridge member is undeflected.
