Oh, the black water tank—the pit toilet of RVs. Actually, they are more like a pit toilet than a home toilet, where you flush and whatever is in the toilet begins an underground journey to the local sewer treatment plant.
With an RV toilet, you flush and the contents drop straight down, or through a plastic pipe that descends slightly and eventually deposits the contents into the black tank. When the tank reaches a certain level, you head off to a dump station, attach a special waste hose to a disposal valve, open it, and the contents of both the gray and black tanks flow into the RV park’s sewer system. It’s just like magic! Well, sort of…
But sometimes there’s a problem. Not everything in the black tank flows away. It gets stuck. It attaches to the bottom or side of the tank. You can flush it out with various devices made for that purpose, but they are not 100 percent effective. And if the situation gets bad, the tank can get plugged! And, no, putting ice cubes in the black tank and then driving your rig over bumpy roads is not effective—contrary to what YouTube experts say.
That’s when you summon the local RV waste expert. He has the high-powered hose and other equipment to clean the tank so clean that you could eat off it. (Yuck! We’re kidding about that, of course!)
So, our question today is, have you ever had your black tank professionally cleaned?
