why does toilet water lower when it’s a windy day?
There's a vent system connected to your plumbing. Its purpose is to keep air pressure neutral in your plumbing, so that the bad stuff can go down freely, and to make sure it doesn't come back up into your fixtures (toilets refilling with waste or fumes). However, if it's a windy day, you can have…
The Short Answer
There's a vent system connected to your plumbing. Its purpose is to keep air pressure neutral in your plumbing, so that the bad stuff can go down freely, and to make sure it doesn't come back up into your fixtures (toilets refilling with waste or fumes). However, if it's a windy day, you can have air pressure changing across the vent, which in turn can travel down the stack. The pressure 'behind' the water can rise or lower in response, alternatively pushing or pulling the water, with a change in the visible water level accordingly. Enough pull, and it may even drain some of the water from the basin into the plumbing. For further information, this is a consequence of [Bernoulli's principle](_URL_0_)
