I don't see why that's a problem.

It really is not a problem because the flush has a vacuum breaker. It just looks bad!

so you actually trust those cheap plastic anti flow valves? I don't.

Well, I don't believe the nozzle actually sits down in the water so it's unlikely that even if the vacuum breaker doesn't work you'll suck up black water.

It's probably best to have a couple hoses for different uses, but if necessary one will work.

I think that the main function of these sprayer/flushers is to move the stuff down to the exit point and out of the tank to avoid the pyramid build up. not to make the sides of the tank squeaky clean. there will always be some residue on the sides of the tank and the best solution for that is like you do, put 10 gallons of water in it with some dish detergent perhaps a water softener and slosh it around on the trip home.

My technique is to drain the black tank first, then use the flush. I have one of those clear spool pieces at the trailer drain outlet that let's me monitor the (ahem) color & contents of the liquid being drained. I do flush with the black water drain valve open. I let the flush water go until it runs clear for a while. Every now and then, I will close the drain and let the flush build up in the tank for a "surge" cleaning approach, but I never leave it unattended. I also concur with the separate dedicated hose to conduct this flush.

AND MY INSTRUCTIONS SAY NOT TO TURN HOSE TO THIS FITTING ON UNLESS THE SEWER IS OPEN

And disconnect the hose when not in use so that it doesn't get turned on by a neighbor while you are gone.

A friend of ours had his trailer flooded with Poo water. Trailer was ruined and had to be replaced.
Yuck!

X2, this happened to our neighbors down in Ariz. and they did have to finally just trade it in:(

I have seen this a few times. One hose to the water connection with a Y with two valves. Water for the rv or water for the black water tank. This is as stupid as an rv'r can get. I saw what happened first hand to what happened to a MH when another person turned the black water on and the couple were at the pool. It was ugly and the MH was a total loss. Why take a chance of this I have told guys but deaf ears was what I saw from them but to each their own.

I open my black tank valve and have the flush going at the same time. When it looks like most of the stuff is out I close the valve with the flush running and set my timer for 5 minutes (so I don't forget the valve is closed). I then open the valve and keep the flush going. When the water runs clear I close the valve with the flush still running and count to 60 then shut off the flush valve. Now the tank is thoroughly cleaned. I then fill the toilet bowl i/2 way and add chemicals then flush. Now I am good for one week easily. I also use Charmin no RV approved junk.

I also do the above method the day before I leave, this lets everything slosh around real good without a lot of extra weight.
