Hey, that is mine! But, yes, it is just a bit short. Honestly, the only thing that is a little hard to see is the Alde Yellow Valve in the upper left, and the "Cold Water Shutoff). Everything else needed for winterizing the trailer is included in the photo.

There are three "drains" in the picture: the Yellow Valve, (#1), which drains the Alde hot water tank. Cold water low point drain over on the right (#5) that drains part of the Alde tank and the cold water lines. Hot water low point drain (#5, bottom center) drains the hot water lines.

What is not shown in this photo is the fresh water tank low point drain, which is between the door and the driver's side tire, behind the step.

The important valves, after you drain the trailer, are the valves on the main hot and cold lines near the middle of the photo: Valve #2 shuts off the hot water lines to the Alde, and Valve #4 shuts off cold water to the Alde. (Valve #4 is hidden a lot by the outdoor shower line in the photo).

After the trailer is drained, and the Alde isolated with valves 2 and 4 closed, valve #3, the "Bypass" valve, allows liquid (either RV antifreeze or sanitizing solution) to circulate through the plumbing to the faucets without anything getting to the Alde hot water tank.

The photo shows the Alde plumbing in the "Camping Season Mode". If your valves are not in this position, the hot water may not be able to work properly. There are extensive Winterizing/Sanitizing documents in the Files. The link below will show you "Winterizing 101", and there are sections for the standard 320 and the CS models. With pictures of both the "Winterizing Mode" and "Camping Season Mode".

Great photo, it helped a lot. I am trying to DX a hot water issue, heat works, hot water gives out after a minute or so, I replaced the mixing valve, but still no resolution. I have a full tank of the century fluid.

The valves need to be in that "Camping Season Mode" as in that photo. If not, you can get those sorts of "hot water inconsistencies" you mention. If the "bypass valve" (#3) needs to be closed. There can also be odd things that happen if the outdoor shower faucets are open, so make sure they are closed. Which mixing valve did you install?
