Finally figured out what this valve is for.
It's a combination anti back flow and anti siphon valve for the black tank flush.
The system turned out to be inoperable due to the valve being installed backwards!!!!
Due to its configuration, I can't simply flip it around. I'll actually have to remove the fittings, shorten one of the tubes, then reinstalled the fittings. Of course this means buying a PEX crimp tool. Still better than taking trailer into moron central, the dealership, for repair.....
Their service department couldn't even identify what the valve was, or its purpose...... Had to determine that on my own!!!!!!
