Homeowner kitchen drain unclogger and method

A plumbing adapter for flushing a fluid drain, the plumbing adapter comprising:

• a water supply interface, the water supply interface configured to hydraulically couple with a water supply, the water supply interface including a threaded connector;
• a drain line interface, the drain line interface configured to hydraulically couple with one of a plurality of drain lines, the drain line interface including a stepped adapter configured to couple with each of the plurality of drain lines;
• and
• a conduit extending between and hydraulically coupling the water supply interface and the drain line interface;
• and
• wherein the water supply interface includes a flexible hose having sufficient flexibility to be manually manipulated by a user;
• wherein the stepped adapter of the drain line interface includes a plurality of internally threaded bores configured to threadably engage at least one of the plurality of drain lines;
• wherein the conduit further includes at least one threaded adapter configured to threadably couple to the drain line interface, and alternately to the water supply interface;
• wherein the conduit further includes a right angle elbow between the water supply interface and the drain line interface;
• wherein the stepped adapter of the drain line interface includes at least a one-and-a-half inch bore and a two-inch bore;
• wherein the threaded connector of the water supply interface is a one-half inch fitting;
• and
• wherein the threaded connector of the water supply interface is internally threaded, being configured to fasten to a male pipe thread.

A method for removing a drain obstruction, the method comprising the steps of:

• providing a plumbing adapter for flushing a fluid drain, the plumbing adapter including:
• a water supply interface, the water supply interface configured to hydraulically couple with a water supply, the water supply interface including a threaded connector,
• a drain line interface, the drain line interface configured to hydraulically couple with one of a plurality of drain lines, the drain line interface including a stepped adapter configured to couple with each of the plurality of drain lines, and
• a conduit extending between and hydraulically coupling the water supply interface and the drain line interface;
• attaching the water supply interface and the drain line interface to the conduit;
• coupling the water supply interface to the water supply, such that the water supply interface is hydraulically coupled to the water supply;
• hydraulically coupling the drain line interface to the drain line;
• opening the water supply;
• flowing a quantity of water from the water supply to the drain line;
• and
• flushing an obstruction from the drain line with the quantity of water.
