Black Tank what now?

Originally posted by mjlrpod Perhaps i've been wasting my time and money. If i'm throwing 6 bucks worth of ice in for nothing, I'd rather save the 6 bucks. The concept sounded believable.

Look up "Fit RV" on youtube.. great channel, and he has a great video about cleaning tanks, complete with transparent tank and home made poo substitute...

Remember that the contents of the black tank have to go somewhere, whether into a septic tank or public sewer system. Products containing formaldehyde or other products that kill the bacteria and cover the smell with perfumes eventually wind up in these systems and disrupt them. Biological treatments reduce the smell by breaking down the wastes. A properly working black (and gray) tank will contain the odor and vent them through the roof.

Two things: If you notice an odor, check the sink and shower drain traps to make sure they are not dry. I find that I have to add a little water to the shower drain every few days if we are not using the shower. Second is to not run the vent fan when you flush the toilet as it will create a vacuum and draw stinky vapors up as the tank will be the path of least resistance to fill the vacuum created by the fan. If windows are open and if the fan is on low, this might not be an issue. However, if the fan is on high, the closed door creates enough of a block to air that the fan will pull from the tank through the flush valve when the toilet is flushed.
