PROBLEM TO BE SOLVED: To connect a simple water closet having a deodolant function to a sewer without detaching a closet by laying the underfloor horizontal piping of the discharge pipeline of a simple water closet at a specific angle, cutting off a closet tank connecting piping at the near position to a house on an outdoor part to fit a piping trap to it, and connecting it to a sewer. SOLUTION: The underfloor horizontal piping (vinyl chloride pipe) of the discharge pipe line of a simple water closet having a deodolant function by a balance closet dish is laid at an angle of 25-45 degrees relative to the horizontal line. When a piping connected to a privy closet tank is connected to a sewer, the piping to the closet tank is cut off at a place to the utmost near by a house on an outdoor part and being easily connected to the sewer, and a piping P trap 3 is fitted to the position through a Y-pipe 4 to be connected to the sewer. The P trap 3 is desirable to be largely bent in the bend part, and the sealing water depth is desirable to be 5-7 cm. Further, an inspection pipe (straight pipe) 5 is connected to the Y-pipe 4, and a cover 6 is provided on the ground part to be used as an inspection hole.
