The shower drain is much higher than the gray tank drain valve. I agree, unless the tank is full, I don't see how in the world the water can back up to the shoer drain. Doesn't make sense.....even with the roof vent clogged and not allowing any air to escape. The air in the tank (if empty) would definitely push air up the shower drain as the water flowing into the tank displaces it, but I just don't see how the water could do that. Got me stumped.
