Jim......Your hose connection in the water bay runs to the other side of the coach to the top of the black tank. You have a door panel on the passenger side, opposite the water bay, with no latch. If you look under that panel, there will be two screws. Remove the screws and that entire panel will hinge upward.
Once open, you'll see all three of your tanks. On top of the black tank you'll see the sprayer with a plastic hose plumbed to it. The reason they clog is that when the tank has waste in it, it sloshes around while driving and enters the sprayer. Once you stop, it hardens and dries, plugging the sprayer. This will continue to happen, even if you clean the sprayer.
I fixed mine by removing the hose, leaving the tank sprayer in place and using a 1/8" drill and drilled down through the sprayer several times to open it up. The sprayer is only at the one end and really doesn't spray anything or clean the sensors from that position. With mine drilled out, I get more flow from the sprayer, flooding that end of the tank and rinsing the waste toward the drain.
The hose line has a backflow device in it, so if debris gets in the sprayer or hose, it can't wash back to your hose connection. That's why when you remove your water hose for the hose connection, you always get a back flood of water.
