I have a splitter I use after the water pressure regulator.
One hose goes to the fresh water inlet and the other can be used for the Black Tank Rinse.

When I used full city pressure, I would get a leak below the bathroom sink.
Mine has a valve there that apparently cannot handle that much pressure.
After dealer replaced it twice (under warranty) they recommended that I use a pressure regulator.
Since I started using the regulator the problem has gone away.
Even at reduced pressure the tank rinser does a very good job.

I agree with the previous post that you need a clear elbow or straight piece right at the exit point so that you can see what is exiting the tank.
I use a clear elbow I got at Wally World for $5.

It goes on first and then the hose.
It's kind of gross to sit there and watch you know, but that's the only way to make sure that "Elvis has left the building".
