I’m sure it’s not this simple… but really… couldn’t you just flush the toilet and see what happens? If it doesn’t go anywhere, or just goes outside, maybe it’s not connected to the sewer?
Why is this so hard to figure out?
But more importantly, does it even matter? Aren’t we supposed to be green and all? Forget “gray water”, that’s so last century. These days, it’s about yellow and-possibly-brown (if you’re coming back from Mexico having drank the water) water.
If you hate this house, you must hate the environment.
