PROBLEM TO BE SOLVED: To provide a drain connection pipe at low cost by cutting off bad odor.SOLUTION: A drain connection pipe body is formed by connecting an upper body 17 and a lower body 18, the side of a lower part 14 of a main body 1 is connected to a house-side drain pipe under the floor of a house, and a drain hose of a sink or the like is connected to the side of an upper part 13 of the main body 1 by being fitted to an induction protrusion 7, such that drainage is performed stably without disconnecting the connected drain hose. A descending drain flow passage 2 formed within the main body 1 becomes an ascending flow passage 3 in which a stagnation part 11 is formed for stagnating water within the drain flow passage 2 in order to cut off bad odor while utilizing drain water. The ascending flow passage 3 then becomes a re-descending flow passage 5, thereby stagnating water from the stagnation part 11 to the re-descending flow passage 5, such that bad odor from the house-side drain pipe is cut off. |
