This is called a siphon. Very dangerous in plumbing. It's why outdoor spigots need to be anti-siphon by code in many places. Imagine if the chemicals in a weed killer hose sprayer attachment ended up in your water supply.
I had this happen in a hotel in France. There were three floors of guest rooms. I was on the 3rd floor. I turned on the shower one morning and heard the water going backwards down the pipe. I think everyone was taking showers at the same time and there wasn't enough water pressure for it.
