Eli5 when it’s windy outside why does the water in toilets swish a little bit?
In: 1241
Plumbing system has a vent, i.e. a pipe that connects to the outside air to allow air flow through the pipes as the water flows and displaces air.
As the wind blows, it also slightly disturbs the air in the vent pipes, which slightly disturbs the water.
