1、排水形式不(bu)同
同(tong)(tong)層(ceng)(ceng)排(pai)水(shui)是衛生(sheng)器(qi)具(ju)排(pai)水(shui)支(zhi)管(guan)(guan)和排(pai)水(shui)橫管(guan)(guan)均與衛生(sheng)器(qi)具(ju)在同(tong)(tong)一(yi)層(ceng)(ceng)連接(jie),不(bu)穿越樓(lou)(lou)板(ban)進(jin)入下(xia)層(ceng)(ceng);異層(ceng)(ceng)排(pai)水(shui)的衛生(sheng)器(qi)具(ju)排(pai)水(shui)支(zhi)管(guan)(guan)穿過樓(lou)(lou)板(ban),排(pai)水(shui)支(zhi)管(guan)(guan)在下(xia)層(ceng)(ceng)住戶(hu)衛生(sheng)間(jian)頂板(ban)下(xia)連接(jie),因為(wei)排(pai)水(shui)管(guan)(guan)道(dao)和衛生(sheng)器(qi)具(ju)不(bu)在同(tong)(tong)一(yi)樓(lou)(lou)層(ceng)(ceng),所以(yi)稱為(wei)異層(ceng)(ceng)排(pai)水(shui)或隔層(ceng)(ceng)排(pai)水(shui)。
2、結構不同
異層(ceng)排水(shui)(shui)(shui)系統的衛(wei)生器具都(dou)要有一個p管(guan)(guan)或S管(guan)(guan)用(yong)來存水(shui)(shui)(shui)封水(shui)(shui)(shui),而同層(ceng)排水(shui)(shui)(shui)就不需要舊(jiu)式P彎與舊(jiu)式S彎存水(shui)(shui)(shui)封水(shui)(shui)(shui)管(guan)(guan)。
3、聲音不同
同(tong)層排水(shui)系(xi)統下(xia),高(gao)樓層的(de)(de)居民使用(yong)衛(wei)生潔(jie)具沖(chong)洗時,樓下(xia)的(de)(de)居民幾乎聽不到水(shui)撞(zhuang)擊、流(liu)過(guo)管道的(de)(de)聲音;而異(yi)層排水(shui)的(de)(de)噪音要大一些(xie)。
4、堵塞時處理方式不(bu)同
發生管道(dao)堵塞時(shi),同(tong)層(ceng)(ceng)排水系統可以在本層(ceng)(ceng)內疏通(tong),然(ran)而異(yi)層(ceng)(ceng)排水系統就只能到下層(ceng)(ceng)進行(xing)疏通(tong)。
