It is designed to help you keep the black tank clean. After dumping the black tank, connect city water hose to this connection and add water... as much it takes and and as many times as it takes... dumping between "fills". Obviously, make sure you don't run the black tank over!
To be able so see how clean the water is (If you don't have one), you should get a clear elbow so you can see how clean the water is as you dump the black tank. It connects to the RV dump or sewer connection and the sewer hose.
Leave several gallons in the black tank after its clean.
