Abstract
A self-sealing drain vent cover that allows for a vacuum to be created within piping of a plumbing fixture for unclogging purposes. The vent cover includes a outer cover and a seal insert. The outer cover includes a first tubular body and a first disk top to yield a closed off structure to support the seal insert. The first disk top is terminally and perimetrically connected to the first tubular body. The seal insert adheres to a surface around an overflow port to enclose said port. The seal insert includes a second tubular body, a second disk top, and an annular self-sealing mechanism. The second disk top is terminally and perimetrically connected to the second tubular body. The seal insert is mounted within the outer cover. The self-sealing mechanism is positioned adjacent to a bottom end of the second tubular body and is concentrically mounted to the second tubular body.
