water in black tank

After setting up at our destination, we fill the toilet bowl 2-3 times then flush to make sure water has filled the plumbing lines to the toilet sink/shower in the rv and to make sure there is water in the black tank. This is assuming you're starting out with an empty tank; if not disregard the 2-3 times fill step. When doing #1, we make sure the bowl is 1/2 full of water especially to ensure the tissue that is used by the ladies) is flushed into the tank. #2 requires the bowl be 3/4's full for proper content disposal. Most manual rv toilets that I've seen will only let enough water in after flushing to usually fill 1/5 to "maybe" 1/4 of the bowl. We simply lift or pull the foot pedal or lever and make sure it is 1/4. If your rig doesn't have a blank tank cleaning valve, it would be a very good thing to add. They are mounted on the outside of the black tank about 8-12 inches from the top. They should be used regularly to clean the tank insides especially if you dump before the tank is 1/2 full. Just remember that water is your friend when using the holding tanks.:B
