What causes the water level in the toilet bowl to drop?

In the case of your toilet water levels, when pressure shifts within the pipe system, the water in the toilet bowl is consequently affected. With a decrease in pressure within the pipes, there is a suction effect. The toilet water is pulled to this area of low pressure, and as a result, water levels drop.

It’s usually above the main bathroom. Inspect the opening and pull out any debris you find there. Birds and small animals are known to crawl into vents occasionally. They can create enough of an obstacle to block air flow.

Why does toilet bowl water move when it’s windy outside?

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. This continual ebb and flow of wind above the vent pipe makes the water in your toilet jostle.
