If you have not modified your flush system, that water is just clean water in the first half of the flush system. And can’t flow back as long as connected to a pressurized water system. In the middle the pipes rise a couple of feet or so. At the highest point there is an antisiphon valve that prevents any water being siphoned back to the water connection port. The water in the last part of the system drains into the black tank. And all of that is clean water.
