Working with the industrial equivalent to black tanks makes me think this flusher is not very well designed. When we want to clean out a tank, we set fan spray nozzles so they sweep the floor of the tank towards the drain. You can have dried / caked material laying in there and it's gone in seconds.....but I don't want to tear apart my new TT and re-invent the system......
Headed back out to drain again.
I suspect that the head on these flushers is a standard head similar to what is on a Tornado or a Quickie Flush, but I don't know if the head rotates. Maybe there is someone here who actually KNOWS what is commonly used on RVs.
I do know that the head is most likely plastic with simple holes drilled in it in all around, and the efficacy of the head will depend on the pressure of the water and where the water jts impinge upon, say, the tank sensors and the sides of the tank. Obviously no one size will fit all, so I would venture to say that (a) degree of cleaning will vary depending on tank-nozzle configuration and even from campground to campground, and (b) on average they are probably not as useful as we'd like to believe - more useful as a marketing gimmick. If it just hits my sensors I'd be happy. I'd not rely solely on my flusher for BW tank cleanliness.
