Why does the water in the toilet bowl move back and forth?
Toilet bowls are connected to sewer pipes, and there is air in the pipe between a toilet bowl and the air vent. Wind gusts cause the air pressure in the sewer pipes to fall, causing the bowls’ water to be drawn downward somewhat. When the air pressure goes back up as the wind slackens, the water goes back up a bit.
Why is my toilet water swaying?
When the wind blows really hard above the opening of the pipe, it creates rising air inside the pipe. So, the air tries to rise out of the pipe as a result of strong wind above it. That causes the water level in the toilet to drop slightly. As the gust subsides, the water level rises back to normal again.

Why is there a hole in the back of my toilet tank?
