If you've got a "straight shot into your black tank" it might do you some good. If, however, your dump valve connection (where you'd install that device) is three 90 degree elbows, a slide valve and a "steep vertical climb" from the connection to the entry point on the tank, then pretty much all you'd be doing is "back filling water into the black tank without any possibility of having a "pressure stream" that would "knock the stuff off the tank walls"....

When using it, be sure to keep your gray tank valves closed or you'll flow black tank contents into the gray tanks as that device adds water which can "equalize the level" in all your tanks if the gray valves are open.

Try it, you may like it or you may find that it's another piece of plastic that takes up space in the bucket of sewer fittings.
