Valve ID

Can someone verify what these two black handled water inlet valves on the right side are ? Assuming rinse valves for tanks maybe ? If so, which is for which tank ? Crossroads Cruiser 30RLS

I appears to be a black tank flush inlet. Attach a hose and listen if the flush is working.

If you can access the back side it would help to determine what they are for. I would say 1 is for a black tank flush and the other is the winterizing port to pull from a antifreeze jug. Did you ask the dealer?

I don't own one, but I was curious, and after a lengthy search, I found a YouTube video on a similar model, part of with includes the explanation of those ports.
For those that watch it, the portion you want to see is just after the 4 minute mark.
The upper right port is the black tank flush, the lower right is the fresh water tank fill inlet.
The lower left is the city water.
Interestingly enough, they are not labeled in the video either.
This configuration is going to make winterizing pretty interesting. I wasn't able to find anything about that.
