question for full timers re black tank
Hello Friends. We have involuntarily become full timers... We moved into our motor home in January after discovering black mold in our house. I'm no rookie, we've put 70k miles on our pace arrow o...

I don't have a tank rinser installed on the black tank, nor do I wand it from the toilet. My dump valves are configured so that the grey tank back flushes the black tank. This is what I do when it is time to dump the tanks:
1. top off both tanks.
2. dump the black tank - leave the valve open when it is finished
3. dump the grey tank - it back flushes the black tank as it dumps
4. close both tank valves.
5. repeat steps 1 through 4.
6. Add 3 to 4 gallons of water to each tank - to keep the seals wet and the bottoms of each tank wet as well.
I've been known to repeat steps 1 through 4 a second time.
About once every month and a half or so, I'll notice the odor in the black tank is rather strong - after dumping and rinsing twice. I'll fill the black tank with 5 gallons or so of water, add 8 ounces of Clorox Bleach, then top off the tank. Then I top off the grey tank as well - then let the black tank soak for 2 to 4 hours and let the bleach go to work. I call this "soak time". Then I repeat steps 2, 3, 4, and 6 - and I'm good to go.
After dumping and rinsing (or dumping, rinsing, bleaching, and rinsing) I add 2 cap fulls of Liquid Tide laundry soap to the black tank. My bathroom sink drains into the black tank - so I dilute the 2 cap fulls into a sink full of water before letting it go into the tank (otherwise I'd dilute it into a pail of water and then pour the pail down the toilet). Whether or not it helps to keep stuff from sticking to the walls of the black tank - I don't know, but doing so doesn't hurt anything.
