style="text-indent:25px">家居裝修時一定會涉及到一些管道的安裝，其中下水管道的安裝是比較簡單的，因此不少消費者會選擇自己安裝。那么在進行下水管道安裝時，不同排水方式的安裝方法是怎樣的呢?又有哪些注意事項呢? 下水管道安裝—下排水和側(cè)排水下排水: 下排水是排水口在地面上，下水管豎著穿過樓板，管道直接通向樓下，裝下排水我習慣把返水彎裝在底下，這樣要是還有別的下水，可共用一個返水彎。做下水一般用50的返水彎，要是還有別的下水，就加三通，要用上面途中那種斜三通，這樣水流得通暢。大多時廚房下水都比較復(fù)雜，有時自己都繞進去了，水路之所以難做主要是因為地方太小，櫥柜里還裝著別的電器，如垃圾處理器、小廚寶、凈水器等，有的還要連接洗衣機等。管道安裝過程中螺旋出渣機做冷態(tài)試車和爐排試運轉(zhuǎn)時，必須有暫設(shè)電工配合進行。管道安裝后一定要進行增壓測試。宿州雨水管道安裝需要多少錢</p><p
