The first thing that I did in preparation to de-winterize and sanitize the fresh water tanks was to print out my own article that was written after I did this process for the first time last year. It is all there step by step and while I had a fairly good memory of what I did, I wanted to have it all down in front of me to follow.
I got out the fresh water hoses, the hose-line water filter, and the tank filler nozzle.

The tanks filled with no problem at all - which they should but as we go along you will understand why I make note of this here.
The Roadtrek tanks fill through the door frame - with the 190 and its two fresh water tanks, one fills from the driver's door frame and the other fills from the passenger side cargo door frame. Some find it easier to fill the tanks by moving the valve to fill on the city water connection and connecting the hose (with water pressure regulator) to that directly and filling. We have found it much easier to just use the gravity fill openings in the door frames.

The tanks were full and we were ready for the next step in de-winterizing - flushing the antifreeze out of the pipes. Remember that my instructions for winterizing do not have you put any antifreeze actually into the water tanks - they are kept empty all winter. The antifreeze goes directly into the plumbing. This is when you open all the faucets (I am not going into the details as you can read them in the de-winterizing article. But I took photos this time and want to share with you what you will see and can expect.
|You cannot see it in the photo but the city water valve is NOT set to FILL. It should be straight up and down. This is either a red or black handle valve right above the outside shower faucet.|
When the tanks are empty for so long mold can start to grow in them so it is a good idea at this point to sanitize the fresh water tank(s). It is a simple process and it is also detailed in the original de-winterizing article. It is good to keep in mind that this process is a long process because it involves a four hour wait in the middle. I knew this but we started late and decided to keep on going not paying much attention to the time. We added the bleach mixture to each tank (some water still remained in the front tank) as per the directions in the original article (one half cup of bleach - Chlorox or whatever you have - into each of the two tanks - if you have only one tank, add a cup of bleach to the single tank) and then filled each tank - through the door fill holes with fresh water. Filling the tanks now through the door fill holes now is important as you want to flush the bleach that you just poured down the fill holes into the tanks.
