Toilet Water Plumbing 2017 Vista LX 35F?

[car54Don]

greeting from great white north, not to far north.

Has anyone replaced the water "line in" - on toilet in rear main bathroom.
2017 Vista lx 35F

* I want to know where the line goes once it is thru the floor. On Winnebago 3d schematics, it shows the line going into water cabinet area but doesn't show real clear where it branches off of. At least I can't determine exactly where it goes.
Everything works fine, except had small water leak due to real high shore water pressure. Reduced pressure, removed elbow where it attaches to toilet, applied teflon tape. No leaks. Want to be ready to fix if fitting is compromised and leaks again. I can buy replacement "line in", just need to know where it attaches below.
thanks in advance

It looks like the line is shown on the interactive parts drawings. Really good info but it does take some time to get the controls down to drive it!

There apears to be two builds for your RV and it does change this water line and connection very slightly. The suspect tee may be in about the same place on each , however, so I ran them both in as info. It depends if you have a serial number with 7th digit of 1 or if it is 2!

Almost directly behind the joint in the metal of the wet bay on both?
