2017 T@B 320 CS plumbing guide?

mmcneil72

Finally getting back to learning our fun little camper.  Bought in mid March, towed 800 plus miles home then let it set until an inaugural trip to San Isabel National Forest in CO in July.  Managed to figure out the toilet and the exhaust fan, didn't need anything else.  A big step up from tent camping!

Now we're decoding the plumbing under the sink.  Managed to fill the fresh water tank and purge MOST of the air out of the lines, but that's about it.  No apparent factory guide to the red, white and blue spaghetti under the sink - see photo.

We do a lot of rough camping - no hookups - so often the only water need is the toilet (and #2 goes in the campground pit toilet).  However we want to camp more, including full hookup campsites, so need to learn these systems.

Any EZ Guides to T@B 320 plumbing available?

The blue cold water line with the yellow valve (Alde Sadety/Relief valve) is used to drain the Alde tank.  Briefly compressing the yellow flapper will allow air into the Alde hot water tank (needs an air cushion).  

The metal valve that joins the blue and red lines is the Alde Bypass valve.  It should remain closed (as pictured) until you winterize the system.  If you use antifreeze to winterize the plumbing, you should open the valve to allow AF to bypass the Alde and to enter the hot water lines.  You should also keep it open until after sanitizing to prevent bleach from entering the Alde.

The 2 floor drains (hot and cold) are the low point drains for the hot and cold plumbing pipes.

The valve on the blue line on the left is the cold water shut off.  It should also be closed when you bypass the Alde.  Ditto with the hot water shut off way to the right.

I can’t see the mixing valve well enough to comment.
