I've been using one of those wands for years and years now, .... 4 different trailers ... same wand.

First 2 trailers did not have a black tank flusher. The wand worked great doing a great "power wash". I always used it at the end of the camping season and when winterizing.

The last 2 trailers have had black tank flushers. But the wand still works better. Again, I use the wand when winterizing, or just feel the need to give the tank a really, really good cleaning.

Fortunate, I can dump my tanks at home. So water usage and disposing of the water is not an issue at all.
