1. A transition coupling assembly for use with a vertical pipe during construction of a floor, the transition coupling assembly, comprising:
a body having a first end and a second end, a first opening defined at the first end and a second opening defined at the second end, the body having a first inner wall section extending from the first end to a mid-portion, the first inner wall section having an inside diameter sized to receive the vertical pipe;
a protuberance extending inward from the first inner wall section, the protuberance configured to provide an obstruction limiting how far the vertical pipe can extend inside the inner wall of the body, the protuberance combining with the inside diameter of the first inner wall section to provide a first socket for receiving the vertical pipe;
a second inner wall section having an inside diameter substantially equal to the inside diameter of the first inner wall section, the second inner wall section disposed on a side of the protuberance opposite from the first inner wall section, the inside diameter of the second inner wall section and the protuberance configured to provide a second socket to receive a second pipe to be joined with the vertical pipe;
a third inner wall section having an inside diameter larger than the first or second inner wall sections, the third inside diameter extending to the second end of the body;
a lateral wall section extending between the top of the second inner wall section and the third inner wall section, the lateral wall section forming a shoulder adjacent to the third inner wall section;
a cover sized to fit inside the third inner wall adjacent to the shoulder, the cover having a top surface disposed above the second end of the body when the cover is installed on the body; and,
a locating device extending from the top surface of the cover.
