my house got the same problem. and the plumber did the same thing to what you did. it worked out.
and plumber said it got too much fat into the pipe. ( must be because we used too much oil while we're cooking ). 作者: 飞天雪狐 时间: 21-1-2014 15:15
如果是厨房,十有八九是油渍堵塞。 如果不是全部堵塞,还有一点点下水的话,我一般烧热水烫,水少 了就加热水,通常2到3个小时,会疏通开。我已经屡试不爽了。
