Winterizing Question
Have a 2022 3100RD. This is the first rig I’ve had with a valve to fill the fresh water tank from the city water connection. Is there a step I need to perform to clear the water from this valve in BOTH the tank fill position and the city water position?

Hi Rabbit,
I don’t think so, the city water connection is like a pass through bypassing the water pump using the pressure of the city water to feed the faucets. No need to winterize on the city water setting.2019 GMC 3500 SRW Sierra Denali Duramax

Look in your owners manual in the packet of paperwork from GD. The owners manual lists the various Nautilus systems and exactly what steps to follow to winterize your rig.
Mine has instructions for certain valves to be placed in the 45° position in one of the steps to ensure that the valves, etc, are cleared of water and winterized.Bill & Colleen ~ Schwenksville, Pa

I have the “Universal Docking System” not the Nautilus. The instructions do not specifically address the tank fill valve. Just asking if anyone has knowledge about winterizing it.

I use a compressor to blow the water lines before pumping anti-freeze thru the water lines. I connect the air hose to the hose connection in the docking station and blow some air thru with the valve in the fill position and then repeat for the city water valve position.
If you don't have a compressor you could pump a bit of anti-freeze thru the fill/city lines while running anti-freeze thru the outdoor hot/cold faucet in the docking station by connecting the coiled hose to the hose connector in the docking station.

Winterizing Question
Hi Rabbit,
Thanks for clarification. I just assumed you had the Nautilus, my apologies for that. Definitely a different process. I can’t offer any insight to the process other than to be sure you have your water heater in bypass, the system drained and that the valve for winterization is located behind the kitchen base drawers is open. It is there that you introduce the antifreeze.
You could do like many of us and once ready for antifreeze just blow out the lines. Your call.
Seems to me the hardest part of this job on your rig is gaining access to the winterization valve because you need to remove the drawers.
Here is a picture from the Imagine manual.
Good Luck,
BillLast edited by Redapple63; 11-27-2021 at 09:33 AM.
