I have zero odor leakage after discarding my foot flush Aqua Magic and replacing it with a Thetford Style II. Replacing the flange gasket didn't help. Somewhere in the housing of the Aqua Magic is a leak and the whole housing is open to the tank. The leak may be around the flush linkage. You'll see how lousy of a design the toilet is when you pull it out. There's no sealed connection between the bowl and waste chute. If you look online for pricing (hint PPL), you'll see that there's no reason to buy the Aqua Magic over the higher end Style II.
