Fill the tanks roughly 1/4 full and add about 1/2 cup or so dishwasher soap (liquid) before you leave for next trip. When you get to the site, dump the tanks and most likely they will work. I've tried other methods and this by far works the best for me. The dishwasher soap is made to dissolve the grease and sludge that's grounding the sensors. I also do this every 5th or 6th trip as maintenance cleaning, have not had a sensor give a false reading in 5 years of doing it this way. Good Luck !
Agree 100 percent. Been doing this on 3 different travel trailers over the years and my black tanks sensors work quite well. I don't use that much water, just about 4 or 5 gallons, enough to really slosh the dishwashing liquid and/or bleach around real good. This is the best thing you can do.
Second best is to use a toilet wand, as pictured above. Shove it down the toilet, open the outside valves and spray away.
My current trailer has black tank flusher. I never close the outsdie valve when use it. I attach the hose, turn on the spigot, then open the camper valve. When everything gets dumped, the force of the spraying water will continue to push anything lingering behind, including hitting the sensors. But I found driving with clean soap water in the tanks does the best. I use Dawn, about 1/3 cup and about 4 - 5 gallons of water. Only rarely do I use bleach. Not necessary.
