What is the reason for the 'chemicals' -----in other words WHY do you need to use it or want to use it :H
RVs have waste holding tanks....not treatment tanks
There should be NO odors INSIDE from waste tanks----IF there is then a 'vapor barrier' is bad
(Do you have sewer/septic odors in your House?-----same odor barriers)
So what is it you are trying to accomplish with the use of chemicals???
Not trying to change any ones methods/ideas.......just trying to understand what it is about RV waste system that requires different approach then same waste system in S&B
I use water and have GREAT results......
