Winterizing

[Olefrank]

I have a 2019 Thor Gemini 23TR. I'm winterizing it. I drained the water tank by opening the 2 valves in the back of the coach. The holding tanks are empty. I put antifreeze in the water tank and then ran the faucets. They all ran until the pink showed up. This RV has a tankless water heater. Is there anything I need to do to drain its lines. I can't see any other valves but I'd like to make sure. I tried finding schematics showing the water lines but could find nothing. I sure would appreciate help on this.

Girard says not to do anything special with their water heater when winterizing. It is ok to run antifreeze through it.

Surprised you had to put antifreeze in your water tank. My Axis has a three way valve that lets you bypass the tank and suck antifreeze directly from the jug.

Thanks. I dumped it in the tank since I didn't have a pick up tube and wanted to get it done. I know I'll have to clean out the holding tank well next spring. I did find a couple of valves under the drawer located under the stove top. i opened those and hear water dump. A while back I saw a schematic and hoped to get it again and print it out this time. I'd like to know where all the wires and water lines are.
Again, thanks.

Here's what I got from Thor regarding the request for schematics for my Gemini: schematics Compass-Gemini (RT-GT) 23TR, 2019.pdf
I hope this works. If not, drop Thor an email with the request.

Use hydrogen peroxide next spring after flushing your tank

It oxidizes the bittering agent residual on the tank and line surfaces

Simple and safe

Thanks. I really appreciate it.
