Dirty water overflows and inconveniences are removed. In addition, when washing mop cloth and articles in the washing pool, the sewer port is often plugged with a rubber stopper or cloth. When the plug is removed and the water is drained, the dirt will be flushed into the sewer and easily become blocked.
