Check valve columbus 320rs

Wife and I picked up our new 2015 columbus 320rs last weekend. We took it out for a one night stay. After trying to flush out black tank noticed no water going into tank. Have read in other threads check valve my have been installed backwards,
Questions are where's the check valve located? And dealship is about 50 miles away, Should I bring it back or change it myself?

Thanks for everyones help with this

Check valve could also just be stuck.
It's right where you hook up the hose.
Pretty easy to get to.

My money is stuck.

They (Valve) are normally directly behind the (Garden hose hookup).The Pex goes (Up) the wall to the valve then returns (Down) thru the floor into the tank. Most of the time in a Very (Inconvenient Location)! Youroo!!

Thanks for the replies

Picked up from dealer earlier this week. The person that worked on the trailer stated whoever put the black tank flush line in ran it between the plywood floor and frame, figure that one out no wonder water wasn't going in.

It's fixed now and ready to geaux, if you know want I mean

Will try it out this weekend
