dumping gray water, apparently no vent?
Black water dumps fine. Gray water tank is obviously not vented. Should it be? What can I do to overcome the vacuum issue while dumping?

IF the Air Admittance Valves failed grey tank would still drain properly unless vent line is obstructed.
Reason for the AAVs is to keep 'P' traps from getting sucked dry when drain grey tank.
Grey tank vent is plugged.
Need to go up on roof, locate vent and clear the vent pipe
