Abstract
Improved apparatus for unclogging a toilet. The apparatus includes a resilient sealing ring shaped generally to conform to the shape of the rim of a toilet, a support plate attached to said sealing ring configured such that a force exerted on the support plate is transmitted to the sealing ring to compress the sealing ring against the rim of the toilet forming a substantially airtight seal around the toilet bowl. The apparatus further includes a sealing device insertable into the toilet tank including a sealing surface configured to form a substantially air tight seal over the vent tube, said sealing device further including a member configured to mechanically block the operation of the valve such that air is substantially prevented from escaping from the bowl through the tank when the sealing ring is compressed.
