Gray water
Gray water from shower and bath lavatory. Can this tank leak if the tank is overfilled?

YES it can leak
Drains from sink/shower go into top of tank as does the vent pipe
Some RV MFGs glue the pipes to tank fittings
Some RV MFGs use 'grommets' that the pipes slip thru......this type allows for slight movement of tank/pipe but can leak if tank is overfilled
Shower is typically the lowest point so when trank is overfilled it should backup into shower pan.
But that also requires tank level to be high and if grommet is leaking water would come out from there
Also there is the possibility of tank crack
This is also quite true. Depending upon the connections to the vent and the drain at the top of the tank, it could easily cause a leak if the connections are loose. I had a similar issue in my past coach and finally just learned to live with it and ensured I never overfilled the gray.
