If one of the two grey tanks totally fills will it overflow into the 2nd grey tank or back up into the sinks etc.

I can tell you my shower became a bath tub so I would say the tanks back up. Thankfully Judy was close by and I yelled to her to go out and pull the grey tank handle. She asked which one and I replied all of them, I am drowning.

Unless you open both gray tank valves and keep them open, the full gray tank will just back up to the sink (or shower if it is gray tank #1).
