For anyone who hasn't seen how this really works.

This guy also debunks the ice cube myth in another video . . .

Interesting video. But if you look at an actual RV black tank, the bottom is not flat, but molded with the slope front to back AND TO THE CENTER. A (any) rinser at the opposite end of the drain will push the debris out the drain.

Not what I would call a "real" test, but it does show an intank rinser is better than the clear piece with the sprayer.

As far as the ice cube video, his "experiment" is in the bed of his truck. I don't know of a trailer that rides down the road as "smooth" as that. Anybody that has put stuff in a trailer and found it on the other end can figure out these things have some bounce.

I was entertained to a degree.

You beat me to it.. But I had to get to bed because 4am comes early when you're my age...

Here is a drawing of a 38 gallon tank similar to what is in my Cougar..

As can be seen, the fellow in the video wasn't using the proper design of prop for his experiment and so the results are for all intents and purposes invalid...

The real point is the in tank flush works better than anything, in a really short time. Where anything without a straight and direct shot into the tank from outside does very little. The full tank fill and rinse did very little.

I also know my wand (old trailer) would take twice as much time, effort and mess and finally produce the result of sensors not registering. The new trailer flush does it in a couple minutes.

I think the guy put an inordinate amount of the and effort into doing these videos. IMO the shape of the tank would have made minimal difference to the outcome. Until, someone takes the extra time and effort to build a clear odly shaped tank and repeat this effort, I'll accept his results as better than what we can tell from the outside, not looking in.


And yes, it was humorous watching his wife try to wash a pan with ice cubes.

That's the only way to clear it in my experience. I let my tank set full of water and Ridx for a month to no avail. I had to get under there, cut the hose, unscrew the plug and stick a wire in to break it up as well can clean in out of the hose. No idea how it got backed up but it did.
