Abstract
A method and apparatus for freeing an obstruction from a plumbing fixture using a flexible diaphragm. The diaphragm is constructed of flexible membrane and is adhered to a top ring of the plumbing fixture. The diaphragm is operated by allowing air into the space between the diaphragm and the wastewater through an air valve and then pushing and pulling the diaphragm to create forces of air that dislodge the obstruction.

A method of freeing an obstruction from a plumbing fixture, comprising a top ring, a surface of water below said top ring and a layer of air above said surface of water, said method comprising the steps of:
- a) positioning a diaphragm on the top ring of said fixture;
- b) employing a sealing means to seal the edge of the diaphragm to the top ring of the fixture;
- c) operating said diaphragm by pushing and pulling said diaphragm to create forces of air on said surface of water until the obstruction is dislodged;
- wherein said diaphragm comprises a tab for operating said diaphragm.
A method of freeing an obstruction from a plumbing fixture, comprising a top ring and a surface of water below said top ring, said method comprising the steps of:
- a) positioning a diaphragm on the top ring of said fixture;
- b) employing a sealing means to seal the edge of the diaphragm to the top ring of the fixture;
- c) allowing air through an air valve located in said diaphragm into a space between said diaphragm and said surface of water;
- d) closing said air valve by pinching it;
- e) operating said diaphragm by pushing and pulling said diaphragm to create forces of air on said surface water until the obstruction is dislodged.
A method of freeing an obstruction from a plumbing fixture, comprising a top ring, a surface of water below said top ring, a layer of air above said surface of water, and an overflow pipe, said method comprising the steps of:
- a) positioning a diaphragm on the top ring of said fixture;
- b) employing a sealing means to seal the edge of the diaphragm to the top ring of the fixture;
- c) temporarily plugging the overflow pipe;
- d) operating said diaphragm by pushing and pulling said diaphragm to create forces of air on said surface water until the obstruction is dislodged;
- and
- wherein the diaphragm comprises a tab.
