I have a mystery pipe in my garage which spews water occasionally (can't tell when why). The black flexible pipe is just a small pipe that connect to any drain and just lies on the ground. This is how the previous owners left it. The water that comes out of the pipe can be cloudy/dirty with food particles which makes me think this is connected to the kitchen sink drain somehow.
What's the purpose of this pipe? Where should it lead to? What should I do with it?
