Abstract: The present invention is directed to a system for reducing the noise that enters the vehicle compartment through a hole in a drain plug. In an embodiment, the system includes a drain plug with a washer, a shank with an inlet fluidly coupled to an outlet, a cylindrical wall and a disc configured to occlude the outlet. The assembly may include a seal. When installed, the seal seals the washer to the mounting surface while the disc occludes the outlet so as to reduce the entry of noise through the drain plug while providing a passageway that allows the accumulated water to drain away.
