所述洗涤水水源来自洗漱池8、地漏9、浴缸10、洗槽11和拖布池12。
所述透气立管3伸顶屋面并设置透气管帽18，所述透气立管3设置立管检查口4，透气立管3下管口设45°弯头经短管连通中段斜三通15。
所述辅助透气管20水平设置；辅助透气管20管口设置45°弯头经短管连通下段斜三通19；辅助透气管20管口伸入透气管井22并设置弯头连通透气管帽18。
其工作原理如下：
本系统配置无存水弯蹲便器，盆内的污水污物可利用重力下落，下落到S型存水弯的水封里暂存，只用少许水量(0.5—1升)涮洗便盆，刷洗后的水排入水封。全部洗涤水流经S型存水弯水封，水封里的污水污物在洗涤水重力势能作用下被冲出，并继续推送进入化粪池。本系统排水立管A段设置气压差透气管，可促使立管内空气流动、清新，确保各卫生洁具在静止和排水状态时，异味不逸出。
无存水弯蹲便器：1.结构简单，价格低：售价为同品牌水封式蹲便器的二分之一。2.技术可行：无存水弯蹲便器排水口的下方管道配套设置S型存水弯，S型存水弯的水封功能等同并超出水封式蹲便器的水封功能。3.适用地域广阔：我国北方地区冬季寒冷，水封式蹲便器水封部位易冻裂或冻实，被迫中断使用。S型存水弯深埋地下不受影响。冬季使用时，停用水管，水箱冲厕改为提水冲厕。4.产品配套：无存水弯蹲便器排水口设置蹲便器防臭阀，市场有售，价格单只6元至60元不等。
S型存水弯：1.本系统涉及的S型存水弯及其他管件，管材均为UPVC制品，市场通用，便于采购。S型存水弯区分有门型和无门型，本系统适用无门型。2.本系统S型存水弯发挥两个功能，一是防臭防虫，二是暂存污水污物。110毫米管径的S型存水弯水封容积为1.5升，经计算，利用一半的容积可暂存2.5个成年人一天里产生的污物。污物的比重略大于水，置于水中先浮起后沉没。本系统运行时偶尔会有污物滞留于弯底，但不会影响S型存水弯的水封功能。
S型存水弯定位：本系统中，S型存水弯定位是施工细节，关系到系统内在的品质优劣。S弯水封相当于一个基准面，洗涤水重力势能的大小取决于它的位置，低位大，高位小，如S弯水封处于负1米的位置，此时处于地平位置的地漏，排放洗涤水的重力势能刚好为1米。洗槽和洗漱池则为1.6米。如S弯水封负1.5米，地漏即为1.5米，洗槽和洗漱池即为2.1米。因此，如果受室内外高差和排水进户管长度坡度的限制，S弯处于高位，即用P型存水弯替换S型存水弯，再调整排水进户管长度坡度比，以降低水封高度。1米和1.6米已经很可观，接近老式蹲便器高水箱的1.8米，大于现标准配备背水箱的0.6米。本系统运行时，洗涤水为动态水量，时大时小，时有时无可不必关注，两个数据提供保障：1.日常生活中洗涤用水量大于冲厕用水量，比例为7：3，即七分洗用，三分冲厕。2.重力势能比，如上所述洗涤水的重力势能为变量数值，施工中可通过技术手段获得最大取值，均可大于0.6米。
气压差透气管实验记录：试验环境、六层板楼的五层和六层楼梯间，外墙窗开启。实验材料Φ50毫米UPVC管材、蜡烛、香烟、纸片等。实验 过程：Φ50管制做成“L”型；L型中段为直管段，右段为弯头，弯头管口水平放置；左段为1米管段六节，以2米、3米、4米、5米、6米等五个梯次增高，同时观察弯头管口的反应，Φ50立管垂直固定在楼梯扶手上。实验反应：立管增高到5米时，效果显现：1.蜡烛和打火机的火苗明显倒向弯头管口。2.烟雾进入管口，不在管口弥散。立管增高到6米时，薄纸片吸附在管口上。实验结论：大气环境中两个管口垂直高差大于5米时，管内空气流动明显，气压差做功。
功能区：排水立管A段为本系统的功能区。现场制作时，排水立管A段为一小段UPVC管材，管外径110毫米，壁厚3.2～4毫米，长度约为1米左右，现本系统以此管段连通蹲便器、S型存水弯、洗涤水管口三通(连通洗涤水干管)、透气管口和辅助透气管口三通(连通上下透气管)共五个部件。五个部件在排水系统中均有独立功能，在功能区集合为整体功能。不同的是，五部件的独立功能在本系统功能区获得放大：1.蹲便器选用无存水弯型，利用直落式的构造放大了其节水并且不污染功能，而且价格低。2.S型存水弯利用水封容积放大了其存储功能。3.洗涤水利用位置能放大了其串级用水功能(废水不经处理重力转送到可以接受的生产过程或系统中使用)。4.透气立管设置并利用检查口和45°配管放大了其管道疏通功能。综上所述，本系统功能区单一部件功能被放大后，系统整体功能随之被放大，使系统具备节水冲厕功能，共同构建了平房排水冲厕系统。
另外，1.排水立管B段和排水进户管连通的弯头应选用45°双弯头，弯头和管径同时增大到Φ160毫米。2.系统需要疏通时，可在蹲便器排水口进行，如不便拆装防臭器，也可在透气立管检查口进行。3.辅助透气管从室 内地平下出外墙后，连通室外透气管专用小型管井。管井中心设置弯头连接管帽防鼠，不设向上立管，管井盖板留较大孔洞便于空气流通。对于透气管高差大于5米的需求为伸顶高度，平房高度，管井深度的尺寸相加后，以伸顶高度调整。
本系统善用资源，原理清晰，造价低廉，不用电，不污染，不堵管不需操作，易普及，节水减排，简单实效。所述平房排水冲厕系统作为一种节水冲厕技术为我国农村厕改增加一种选择。
