The issue on this new to my daughter 1982 C-30 is that the holding tank is full and cannot be pumped out. Twice the pumpout facility has been unable to remove anything from the tank. I removed the vent line from the top of the tank today intending to attempt another pumpout and determine if the vent line was plugged. Wellll, that is how I found out the tank was full. I quickly put the vent line back on the 90 degree elbow and cleaned up. Assuming the discharge line is blocked is it possible/advisable to "snake" the discharge line starting at the deck waste fitting? Thanks.
