Winterizing 8289WS

This is the first winter with our 8289WS and I was looking to antifreeze it. It has the winterizer port on the outside. It says close the valve to the tank and open the valve to the inlet. I know where the hot water heater bypass valves are. I tried sucking the antifreeze in after closing the hot water heater bypass but nothing happened. I did not see anything else in with the water heater. Does anyone know where these other valves might be?

There should be a panel in the basement (same side as antifreeze inlet) that you remove which will expose the water pump and water lines. I have a rockwood 8280 and panel is attached with 5 screws. Once removed you will see all of the various water lines. One of them will have a black valve that you can turn which will allow you to siphon the rv antifreeze through the inlet.

It is the same on the 8289WS. There is a three way valve on the input line of the water pump. You'll need to get into that area anyway to drain the filter, if you haven't bypassed it.

Thanks, I will take a look. The manual tells you nothing but fill the fresh water tank.

I found it, and that did the trick. Thanks for the help.

For winterizing the rig, I use compressed air. I open the drain vales and also drain the water heater. I then blow compressed air through the city water inlet. I open the faucets in the rig one by one and let the water spit out. Don't forget the shower and toilet.

After closing the drain valves, pour RV antifreeze down all the drains and into the toilet. I have found that this method also blows all the water out of the water filter.

I did this many times last year and had no issues. We use our rig all year long, so I end up winterizing it several times each winter.

What about the 12V water pump, could that freeze and cause damage? As far as I can tell blowing air through the city water inlet does not clear the the pump and the few feet of those lines.

Good point. I did not do anything about that, and never had problems. Perhaps I should blow some compressed air into the fresh water tank while running the water pump. That would clear the lines, yes?
