Some bathroom sinks on NEWER RVs did plumb sink drain to black tank.
Regardless......
Sink faucet would have to be running/dripping and/or toilet water valve would have to be running/dripping to cause well pump to cycle on
The more I replay this nightmare in my head I think you may be correct. The bathtub did not fill with any water which is usually the first indication of a full grey water tank. The grey dump valve left open and the well pump cycling might just be coincidences that I thought were related to the problem. Of course the black tank monitor doesn't work either. I think I can pin it down tomorrow.
