Tab 400 == Plumbing Diagram - - Draft

There are several threads & resource section posts on the Tab 400 Nautilus System Operation however I've not located any diagrams for the general Plumbing of a Tab 400.  We have Tab 320 diagrams (~2016 version) that are still useful with today's production models yet no Tab 400 diagrams . . .

As part of my "Tab 400 Most Likely Next Trailer" {since 360 has a cassette and weird kitchen} I'm researching/investigating the Tab 400 systems.

TAB 400 owner observations, comments on the attached PDF file plumbing diagrams are welcome.

Do keep in mind that there has been a lot of variation since the initial 2018 production year . . . goal of diagrams is to capture most common or most current plumbing configuration nüCamp is using.  I've tried to show 'connections' that is the T Joints in the correct sequence for a given line.  Everything is based on various posted plumbing pictures.

Side Note:  One owner reported nüCamp told them the Kitchen CW line had a Check Valve at the sink . . .? . . . perhaps due to the Sink Faucet design?
         Any other items like that . . . 

nüCamp has above average Build Quality and with the Alde a luxury heating system yet they lack documentation for owners.  A few RV Builders do provide greater detail/information. InTech being one of the better examples with Model & Year referenced schematics/diagrams for nearly every trailer they build . . . would be nice if nüCamp did so as well . . .

    Not a single Comment, Like, or Agree so far . . .

    Is this topic/information of no interest?  Or so incorrect No One will Correct it   ;)

    Confused here.by lack of feedback.

    This is a useful project for many, so I too was hoping for some feedback. My suspicion is that a lot of folks have their 400s stored away so not so easy to check the plumbing configuration.

    I’m about to take my 400 out so will look around but my 400 does not have the Nautilus. Just a single bypass valve for the Alde water heater.

    The schematics are a worthwhile contribution! Thank you! However, it is difficult to comment, in part because that requires transferring a visual inspection, in my case of the Alde compartment and the bottom of the closet, to a diagram representation. That is not so easy to do, at least for me. I can say that the 2018 model, and perhaps all of the pre-Nautilus ones, have three low-point drains near the Alde: cold water, hot water and Alde. I believe the only check valve is to prevent backflow to the fresh water tank, but I don’t know exactly where; I haven’t recognized one yet.
