Black holding tank censors

I do not use any chemicals, I do not add dish soap or water softening powders or follow the geo method. By and large my sensors usually work correctly. Once in a while one acts up, but it's not the norm. Make sure your tank is 3/4 full or more and use the 3 inch drain hose and let it drain. I do have an installed aftermarket tank sprayer. But after I've have to replace two sprayers and had three different times where the hose blew off and soaked the insulation of the underbelly; I would not recommend the aftermarket Camco tank sprayers.
