Trying something new with balck water drain

For the last 2 months I have been hooking up my black water flush line before opening black water valve. Then I open up the black water valve about 1/4 open making sure it is flowing then I turn on the flush line and let the spray mix whatever is in the tank making sure the line continues to drain. So far it has been working well. Hope it may help if you decide to try it.

So how did you do it before the last two months? Opening the flush line before or after opening the black tank valve (drain?) shouldn't make any difference unless your tank is 100% full. Also, you might want to open your gray tank valve first (instead of opening the black tank 1/4) for a few seconds prior to opening the black tank. Cleaning up the gray water is a lot less of a problem than the black water.
