抽水马桶

I flushed the pills down the lavatory.

我把药片丢进马桶冲掉。

Install a flush toilet with small pondage.

安装一个贮量小马桶。

The lavatory won't flush.

马桶不灵。

94. unstop a sink, toilet, drain, etc

疏通洗、马桶、下道等.

The worst thing is that the water closet is clogged and when I flushed it, it overflew.

最糟马桶堵住了，我一冲，就冒出来。
