As long as you poke a hole in the blockage the pressure eventually forces through, as long as the blockage is not hardened. Same thing happened to me. I guess it is not the U that is usually blocked.

有一個方法就係將水注直接射入個去水口,更好既方法塞水管落去沖

呢個單位不是用 樽型隔氣,塞渠未必先塞 U 型位。而且現用的 U 型隔氣裝有 防啜力裝置, 疫情期間,好易病毒從 防啜力位傳入。 最好用回無啜力裝置的 樽型隔氣 比較。安全 dd。
