Water connection not labeled

[6stringminstrel]

Just acquired a 2018 Cougar 30RLS. In the maintenance compartment, the city water connection is labeled, but two other water hose connectors are not labeled. We assume they are tank flushing connections. Ideas or experience with the panel shown in the attached picture?

It would bey guess based on location, the one on the right is the black tank flush and the one on the left is for winterization. Ashley section of hose into pink antifreeze, turn winterization valve turn water pump on and pump thru water lines

^^^^Terry would be right.

The cautionary label under the connection on the right advising not to use the black tank flush unless the termination valve is open would confirm this in my mind.

That makes sense. Thanks for the response.

I’d say far right black tank flush second from right city water connection. 3rd from right fresh tank full and far left winterization. Just my ideas
