Rhino Black Tank Connector Elbow

The Rhino flush valve probably isn’t “better” than the installed flush system, but it is more convenient because it is on the same side as the tank drain valve. You can use the Rhino coupling every time you drain the tank.I hook a water hose to the Rhino unit at the same time I hook up the sewer hose. There is a valve on the Rhino unit that opens and closes the hose connection. Once the tank is initially drained, you open the water hose valve and water goes into the tank under pressure. You watch the water going in and as soon as it starts reversing, you shut off the hose and let the tank drain again. You can easily see the results as you stand next to the tank drain and can repeat the procedure as many times as necessary until you get clear water exiting the black tank.

We have the same connector. Agree that it works great. The black tank is clean. The only downside that I have experienced is that sometimes the line at the dump station is so long that I feel guilty using it.

I was out shopping last week and decided to buy the new model (I think) of black tank connector. It's the usual 45 degree, clear tube. But this one has a port that you can attach a hose to it. Once you've emptied out, you can blast a stream right up the black tube. I tried it today and it worked really well. By the time I finished, the water was coming out pretty clear. I've never had great luck with the high pressure wash that comes with the camper. I know many dump stations don't supply a garden hose, but if you go to one that does, this thing is pretty good. I have stopped going to the rinky dink dump stations that many campgrounds have, and I go to my nearby dealer. For ten bucks I get free gloves, their sewer hose, and a nice garden hose all ready to use. Well worth it.
