Black water tank filling up

If you leave the valve open all the time you're hooked up to sewer you will probably build the famous "poo pyramid" in the black tank.

X2. My first trip as a newbie we camped for a week with the valve open .a weeks worth of liquids runs right out. A weeks worth of paper will plug everything up. I now run mine up to about 2/3s then dump. Every other day or so. Never had a black tank problem since.

One point not mentioned, is that your system is a chemical toilet, so the solids and paper are 'breaking up' while they sit in the chemical. This makes it easier to get a good clean dump.

(Clean? - OMG)

Not exactly. The black tank is just a tank, not even a septic tank, just a reservoir. Same thing for the grey tank.

If you add chemicals or probiotics/bacteria to digest and liquefy the waste then you would be correct but some don't add anything, some use the Geo Method (water softener and detergent).

So, why do I need to add chemical?

Didn't you answer this already in your post #22?

I think whatever method you choose the goal is to break it up so it has an easier time draining out.

I do it mostly for odor control.

Another benefit of using chemicals!
