Where is water heater bypass 2020 321RSTS

[rmorrison9773]

Next week is my last week of camping for the season so I would like to winterize before I leave the campground. I can't find the water heater bypass anyone with a 321 RSTS able to help. Thanks in advance

Your unidock with all the water hookups has a setting for winterize. It does the bypass on the hot water heater. I am assuming your 321rsts has the same unidock.

I was just researching this and the above post is correct. I’ll add that believe it or not, the manual has more detail about the system that’s actually useful. I was surprised.

Thats where I found the information. Our manual had two different dock configurations. It actual works pretty well.
When winterizing couple things to remember Don't forget to pump a little pink stuff into tje black tank flush.
If your unit has the washer prep you need to pump the pink stuff into the washer hot and cold lines. We don't have the washer so I added two ball valves to block the lines up to the washer prep from the low point drains door side in basement.

Even if you don't have a washer and dryer or haven't use it and if so how do you go about it?

I use a washing machine hose to run the antifreeze into a bucket or out the window on each hot and cold. If you have a washer, it will tell you how to winterize it in the manual.

When I have finished adding antifreeze, I just open the low point drain and open each of the washer valves. This allows any water / antifreeze in the lines to run out .

With my previous trailer, if I took it out in January or Feb, I’d winterize before I packed up. This one seems a bit more complex.

Winterizing valves are always behind the WH or on the Uni-dock. The pump AF inlet will be always close to the pump area, Uni-dock or on the outside wall as separate inlet.

Also run some "pink" thru the outside shower.

How would you do this? You don't really "pump" in the antifreeze. The pump sucks it in. Do I can't really see how you could force antifreeze into the black tank flush.

I use the outside hose/shower connection hose inside the unidock on our 321rsts. Thread hose shower hose into black tank input fitting.
With pump on open cold or hot tap in uni dock. It pumps the rv antifreeze thru no problem. I am just ensuring there is no water trapped in the black tank flush piping. It should just run thru the nozzle inside the tank.
I have looked at all the plumbing on our trailer. There are spots for water to lay in the lines. The pex pipe can take freezing but the hard plastic elbows and fitting I think not.
The pump connection to pull water out of the fresh water tank
Is actually lower than the fresh water tank drain. So I pump a very small amount of pink stuff into the fresh tank. Open the fresh tank drain until I see pink
Rv antifreeze is cheap. Fixing burst plumbing fitting is a pain.

YMMV

Had to think about this for a minute but then I got it. Very clever. I'll have to do that. Thanks!
