Review on 🌀 Camco Cyclone Rotating Sewer Plumbing Vent - Eliminates RV Holding Tank Odors, 360-Degree Rotation for Effective Odor Extraction - Black (40597) by Jason Melvin

He works and does his job. It definitely got rid of the smell in no time, but before you get the full result, it's important to keep the tank as clean as possible. This cyclone will do most of the job of preventing the gas, but before you head out put 1-2 bags of ice in the tank by flushing them down the toilet. This will bounce off and remove most of the dirt that has built up over time. Then hook everything back up and wash your back at least 3 times. This type will prevent most of the gas, but it's also important to make sure the tank is as clean as possible.
