My toilet blew all the water out of the bowl. I went into the bathroom and there was water all over the toilet seat and the floor. The bowl was dry. When I flushed it, it returned to normal. There is no plumbing above it, so what’s up? I’m baffled!
I have seen situations when municipalities have been jetting a sewer main and have caused back pressure to discharge from the toilet. It has been known to scare the shit out of people sitting on it at that moment.
Sounds like you have a blocked drain and then empty’d either a bath or washing machine to cause the blow back of air
