AND..... once you get the problem solved, in the future, if you are not already doing it - never never never dump the black tank unless it is at least 3/4 full, even if you have to add water first. Also, leaving the dump valve open when connected up to a sewer inlet is bad practice as it can cause a build-up of solids in the black tank. It's actually quite surprising how many folks I have seen at campsites who leave the black tank dump valve open while connected to the sewer system.

Got things working again. I had (briefly) considered trying to backflush the system, but couldn't figure out a clean or safe way to to that. The level in the toilet had dropped enough that I thought I had enough room to use the Turbo Wand. I had tried the OEM flush system, but got a sprayback at the docking station that makes we wonder if it's installed correctly.

At any rate, after about 30 minutes of flush/fill/dump/repeat, I was getting reasonably clearish water out. I added a full bottle of tank enzyme treatment, a couple of gallons of water and called it a day. More later when I get wifi. Thanks all.

Likely your OEM Flush system was clogged with junk IN the tank. There is a backflow preventer in the line to the black tank to prevent black water from being pushed (or siphoned) out of the tank through that hose to the outside of your rig.

If the line is blocked at the tank the backflow preventer will not allow water to enter the tank and will gush water out when you disconnect the flush hose. Most likely it is working fine and will work properly when you get your black tank stabilized and cleaned.
