I have owned 3 Newells over the last 18 years, and I never understood how the odor control system worked. Thank you Richard for explaining it. I have seen the control knob but I didn't know that you had to add salt to the sewer tank to make it work. That is why I have been buying Always Fresh and adding it to my sewer tank. You have just saved me $$$$ Richard, thanks again.

Salt is much cheaper than Always Fresh!
