2024 Tab 400 Boondock and Black Canyon Winterizing: Schematic of Valve locations?

Mother_Tree

I am frustrated by the lack of schematic drawings that assist the owner in winterizing.  We have “text”, but under my bed, the lines are not like any I’ve seen online, and the yellow valves seem to require that you hold them open to drain.  Any suggestions, my fellow NuCampers?

Welcome to the Forums.  You have the Nautilus 3.0, and the manual has the rundown on the basic valve positions for the various functions.  The "Nautilus Panel" is on the driver's side of the trailer.

In your 400, the two yellow valves are down near the Alde.  They are spring loaded devices that are "closed" when horizontal and open to drain when pointing "up".  In the "up" position, they should stay in that position.  

Your other "low point drains" for the hot and cold water lines are on the driver's side of the trailer, on the frame just behind the wheel.

I have the picture below marked as a "2023 400".  This is what the drain "handles" look like in most of the Nautilus trailers, but NuCamp does make various changes from year to year.  This photo shows the hot and cold water low point drains, and the fresh water tank drain.  If your fresh water drain is not located in this spot, it may be over on the frame rail on the other side of the trailer. The little round  white "tubes" are where the water actually drains from each low point drain

The "blue spout" in the photo is the "fresh water tank vent" and overflow spout.

Welcome to the Forums!  Start with the Nautilus manual, and that will help a lot. Keep in mind the Nautilus is a "generic" product, not specifically for the NuCamp trailers.  

Please do not hesitate to ask questions as you go about this.  We love questions!  There are many owners here who have used the Nautilus for several years to help, and there are tons of threads with advice.

Thanks for such a clear response! By your photo I see that I have a missing valve handle. Is this intentional on the 2024 model?  

Horigan

Probably not.  You could temporarily move a handle from one of the other locations to operate it and confirm it functions.  NuCamp may be able to get you another valve handle and screw.

I don't think that is intentional.  Have a good look at the "stem"" where the handle should be and try to sort out the condition of the post itself.  You can see the other handles have the screws that hold it to the post, so check to see the condition of the threads, if you can.  

The parts are available from various sources, but a quick search shows the prices are all over the place. 

This link has the various "handles", but it is not clear to me if the screw holding everything together is included!

Parts can be ordered from various dealers and they will order them from NuCamp and then ship them to you.  Again: the pricing can get strange, so shop around.

We can help with that sort of thing, too.

Excellent suggestions!  I’ll take off one of the other handles and “open” the fresh water valve...

Mother_Tree

It appears that the threaded part the handle screws onto is not present either.  Oh my.  I’ll have to call Nucamp and talk to someone

Is the "stub" where the handle goes "splined"? Does it have grooves that the handle will fit into?  The grooves/splined handles would give support to helping the valve turn, and the screw would just be there to help hold things together.

Never seen a situation like this, so please let us know what NuCamp thinks.
