Black tank - unpleasant surprise
Took the TT out for my 3rd trip. When I went to connect the sewer hose I took off the cap and had brown, smelly water splash out onto the ground. I had drained, filled, and drained again the black water tank after my last trip and then added the water/chemicals.
So my questions are why did I have black water coming out when the valves were closed? Is this normal or does it indicate a problem? Are you supposed to open the cap with a bucket underneath? This is so gross that if I have to deal with this it could be a deal breaker.

I had found that with the cable operated remote valves, there is always some water that drains down from the pipe. I added a twist on valve at the connector that you hook up the stinky slinky.

If you want to test the remote valve you could put some water in the black tank, leave the cover off of where you hook your tube and put a bucket under it. If the valve is leaking, of course there will be water in the bucket.

Possibly your valve was not completely shut or you had residual liquid left in the pipes. I put a twist on slide valve and a clear elbow on the discharge so I can see if there is anything behind the cap.

Ditto on the "end of line" valve.
It prevents "wet shoes," when:
1) Any tank valve leaks due to dry seals
2) Any tank valve fails to close due to a cable or stem cotter key failure or TP stuck in the valve's slide way.
3) Quickly shut off the flow is you have a sewer hose spring a leak while dumping or your portable holding tank starts to get full before you are finished emptying.
or
4) Some wise guy from opening your black tank valve; then pushing it closed when you stop for lunch.

I had it happen once in 8 years. Tank drained, valve closed then RV towed a few hundred mikes and bam! About 1 gallon blew out. Seemed like it was under pressure.

Exactly the same happened to me after my last trip, found it while winterizing right there on the ole driveway. No idea what happened. Never happened before, hopefully never will again.

Had the same thing happen to me when I took the ol 5er out on its maiden voyage. Pulled up to the dump station (2 trucks behind me... it was a busy weekend), uncapped the pipe and out came a good bit of who knows what. I thought to myself "Surely this is grey water..." and entered that state of mind as I emptied my tanks... That was aweful smelly grey water...
When I pushed the valve shut, I gave it a few extra whacks to make sure it was shut tight
