PROBLEM TO BE SOLVED: To provide drain piping that comprises a drain port and a side drain port and has piping from the side drain port connected to piping of the drain port and that easily and securely prevent an air bubble from the side drain port from flowing backward when waste water including the air bubble is discharged from the drain port.SOLUTION: Drain piping for a tank body consisting of a drain port provided at a bottom of the tank body, a side drain port provided on a side face of the tank body, a main drain pipe for discharging waste water from the drain port to a sewage side, and a branch drain pipe for discharging the waste water from the side drain port to a halfway part of the main drain pipe comprises a check valve which is normally closed to prevent an air bubble from flowing backward from the drain port at the side drain port, and is opened only when waste water is discharged from the side drain port to allow the waste water to flow toward the main drain pipe.SELECTED DRAWING: Figure 2
【課題】排水口と側面排水口とを備え、側面排水口からの配管を排水口の配管に接続した排水配管において、排水口から泡まじりの排水を流した場合に、側面排水口から泡が逆流することを容易且つ確実に防止する排水配管を提供する。【解決手段】槽体の底面に設けられた排水口と、槽体の側面に設けられた側面排水口と、排水口からの排水を下水側に排出する主排水管と、側面排水口からの排水を主排水管の途中部分に排出する枝排水管と、からなる槽体の排水配管において、常時閉塞して排水口からの泡の逆流が側面排水口に生じることを防止すると共に、側面排水口から排水を生じた場合のみ開口して主排水管側への通水を行う逆流防止弁を備えて構成する。【選択図】図２
