One Black Tank Flush For Two Black Tanks

[BenFish’n]

I have a 2020 3931FB with two black tanks, but only one black tank flush. Are both black tanks connected to the one flush port in the wet closet? I have looked around the trailer and I don’t see a second black tank flush. Thank you for your knowledge and help.

The two tank flush ports you see in the convenience center are both black tank flush systems. The port on the left will flush the front bath black tank and the port on the right will flush the (rear) half bath black tank. Gray tanks do not have a flush system.

That is the problem. There is only one tank flush port, so I was wondering if the one tank flush port flushes both black tanks or if I’m screwed?

To the right of the black tank flush is the Fresh Water Fill. Sorry the pic is not properly oriented.

It would be nice if Keystone had labeled the connections...or maybe use black plastic caps for the black tank flush connections instead of white plastic. These pics are screen shots from online sales videos. My unit is in the shop right now so I can't take a pic of mine.

MikenDebbie,

Thank you very much for your patience with me and the time you took to provide me with the labeled pics. It all makes sense now. With the location of the 1/2 bath black tank flush located amongst the clutter of labels for the fresh water power fill valve I was over thinking what the fill port was for.

I agree, with Montana being Keystone's flagship models, it is so frustrating that they won't take the time to do a better job making the systems very user friendly. We owners paid a premium and those little details should be a priority to keep owners brand loyal.

Would you please share the link for the sales training video that you retrieved the photos from? Thank you again.
