I agree with Camper bob.
This ice video has been around for years and has been posted many many times on the forum. But there are always new people, so I suppose that's OK.
While there are those who "poo pooh" the idea of a black tank rinser saying there is no need to scrub the interior of your black tank, the results that I see flowing through my clear elbow make me a believer.
We use a lot of water when we flush. We don't drain unless we are near full. But once we drain the black tank and then I hook up and turn on the rinser, there is a considerable mass of somewhat thick effluent that is pushed out of the black tank for a few minutes until it begins to run clear. My opinion is that it is better to have that stuff out of my black tank than sitting in there.
Ice in your Black Tank certainly won't hurt, and it might help just a bit so if people want to do that, no big deal. Many major league pitcher go through a routine of touching their hat, scratching or whatever because they believe it makes them pitch better. So who is to say? If you think it works then continue doing it. As for me, I'll use my built-in black tank rinser.
