Black Flush

[BigJohnD]

Well my black flush finally quit. Seems to be plugged up, which doesn't shock me due to the tiny holes in the sprayer. This one is a bit of a bear to get to, so hopefully I can get it out and drill the holes out a little bigger. I got a couple of spare black flush nozzles like that one so I may experiment with the drill hole size first. I've already filled the tank up with water and strong soap in hopes it would loosen up whatever is stopping up the jet, but that failed. Anybody removed one on a 3121 or the SS 3120?

I have never taken my black flusher out but I have installed a gray tank flusher which was easy. My 2012 doesn't have the tank cover panel that the newer models have so it is pretty easy to get to.

Mine has the cover, which is easy to remove, but even then it's in a tight spot between the tank and sidewall. The tubing 90's straight up from the fitting and under the bathroom sink. I believe you're the one who originally helped me dissect the plumbing on this thing. Hoping to disconnect it from the antisyphon valve, remove the flush nozzle and take the whole assembly out, tubing and nozzle. Can't do it now cause we're camping and I can make due without. The gray tank is easy to get to, the black tank nozzle is forward of that hatch opening, back right wheel as yours probably is. Been a while since I had the cover off, I just remember it being a little cramped and thinking if I had to remove it, it wouldn't be just terrible. We'll see soon enough.

How about trying an air fitting used to winterize the water line. Screw it into the connection for the black flush and start with low air pressure. If the sprayer is clogged from the outside this may work. I carry that fitting and a very small air compressor on-board.

Might try it when I get home. You'll never know if you got all the holes unplugged unless its removed and checked / bench tested. I'm putting 60 psi water pressure to it now. I still want to take it out and drill out the holes. I'm not diving into it for another week when i get home. My tiffin did the same thing and drilling them was the most popular and successful fix amongst many. I usually don't let my tank get that full, but we did, now its plugged. No biggy.
