專家解答家居座廁排氣管疑慮 預防細菌病毒散播

曾經有單位內的廁所排氣管因改裝而漏氣,造成新型冠狀病毒經渠管傳播,令人驚覺家中座廁的排氣管到底有沒有問題。今次請到 @裝修中伏大全(裝修學院)的顧問 Andy 講解一下,有關座廁排氣管的用途和保養。

 

Andy 表示座廁排氣管的作用,就是防止樓下單位內的隔氣彎道的水被抽走,令細菌病毒有機會走入室內。
現時法例規定廁所必須有排氣管連接污水渠。
當樓上污水渠排走某個量的水時,會引致樓下單位的渠產生負氣壓,形成虹吸作用,抽走隔氣彎道的水。
但很多人為了美觀等原因將座廁貼牆,將排氣管 cut 走,其實這不合乎法例規定。
因為 u 形隔氣能阻隔帶有細菌病毒的空氣進入室內,要注意維護它的功能。
如果發現家中排氣管已截斷,就要驗查有沒有臭味傳出,與及樓上沖廁時,家中座廁的水位有沒有不正常郁動。有臭味的話要趕快封好渠的接駁位,並盡快找師愽維修。

另外要注意每星期倒半公升清水到 u 形隔氣,沖廁時要蓋上廁板。
