I was a little skeptical of how good this thing was going to work. So after I drained the black tank, I hooked up the water hose and turned it on. With the tank valve open, I let it run for a minuter or so. I was thinking this isn't really going to do much. Well, once the water started coming out, I was amazed at how much "stuff" came out with it. Jerry.
