Options for black tank flushing?

Why do you feel the need for such a device ? Many of us have been RVing for twenty or thirty years with out one !

Your probably right and you have much more experience then me. My personal reasoning is that my tanks are small so I don't have a lot of room to leave extra water in the tank. I try to completely drain it when I leave the site. I also only get the TT out once a quarter. I hate to let it sit stagnate for months. On a last note, my sensors always read 1/3 full. Hoping this flusher can get the sensors back to working.

Thanks for all the replies.
