black tank odors after storage

Hi Roo

Since the tanks are holing tanks and not septic tanks the cleaner you keep them the better.

For the back tank I pour two caps of Calgon liquid water softener in the toilet. It will make the tank walls slippery. Then I travel with about just less than 1/3 tank of water. Let it slosh around while driving. At camp I let it fill up before draining. If not full before draining I fill it. Get a good flow of water when emptying. I also use some little blue packet if deodreizer with each tank.

After emptying the tank I fill it again. Just water. Fill it full. When you empty it the second time you will be surprised how dirty it comes out. I suggest getting a clear drain tube connector. It connects between your sewage tube and your camper connection. It enables you to see how the water is as it drains.

When I prepare my camper for long-term storage I fill it a 3rd time and pour 1/2 galln bleech down the toilet. Fill the tank let it sit 30 mins and drain.

Do this and you should be good.

Thanks GW
The long weekend trip, we had both valves closed...to fill the tanks, found out that keeping an eye on the panel is a must when doing that, since my bff went to take a shower and the shower floor was full of water...luckily it all stayed IN the shower.. shewww.. so pulled the gray water and emptied that, left the black water closed. Then we closed the gray again to refill, so the day we left, pulled the black.. emptied that, then the gray to help flush things a bit. Only did it once though, so not sure it was enough "flushing out" or not.
I'll look into finding the calcon softener before i put more water in the black, and the trip in Sept..I also have those little blue packets as well..
