My wife has finally joined me down here in Florida at the campground. Well, she likes to use a lot of toilet paper. A few days ago, I came home from work, and she told me she thought the black tank was full. A peek inside the toilet bowl confirmed it was FULL. A trip to the rear of the trailer, and the black tank valve was opened. Nothing happened. I opened and closed the valve several times and still no dice. Great, I thought. I got out my handy tank washing wand and shoved it up waste pipe, while carefully holding the waste hose waiting for the avalanche.
It never came. Nothing more than a few pieces of TP and some brown water, trickling out. I poked and prodded for an hour and made no progress.
I really couldn't tell if the valve was broken or I had a blockage. The valve seemed to be open.
I gave up, and dumped a quart of RV digester bacteria stuff from Wally-World in and crossed my fingers. I let it set for 2 days, while we used the campground facilities. (A real pain at 4 AM).
Tonight, I decided to give it a go. The valve opened, the hose started shaking, and the tank emptied
So, if you think you may have a stuck or broken valve, or just a plain old blockage, try using some digester bacteria first, and let it set for a few days. It may just save you a huge repair bill, or worse yet a brown bath.
