Washed & Winterized For the Season

[RDTC]

5th Wheel is put away for the winter. Will look for some off season improvement projects.

Washed, waxed, and winterized it this week.

Winterize Process
- Empty fresh water tank
- Blow out all lines with 25 psi
- Fill fresh water tank with 10 gallons antifreeze
- Use water pump to purge system with antifreeze
- Blow out all lines with 25 psi
- Empty holding tanks
- Clean sinks, shower, and toilet

Probably a bit overboard on the winterizing. But, with potetial lows -10 to -20. Don't mind taking the time to get every bit of water out.

Plan to retire in February. This will open up year round camping options.

Just curious as to why you put so much antifreeze in your fresh water tank or any at all for that matter. I put antifreeze in the rest of the system on my RV but have never put any in the fresh water tank after draining it. Doing it your way requires a really good fresh tank flush in the spring not to mention a whole lot more RV antifreeze solution.

Mostly what I do! We get down to -30 at my place, and much colder where I use to store it for the winter. I need just a bit under 2 gallons using the winterizing bypass feature.

I have never put antifreeze in the FW tank, but In know people that do. I also had a former coworker who's husband fills the water heater totally full and leave it that way all winter. She had no clue why, but it was what he did every year.

As for the FW tank it really does not need any in it as long as you drain the tank. The little bit of water left in it does not have the destructive strength as it is just thin film. In the spring the FW tank will also be much harder to rinse out, lots of water, and time. To ensure the water is out, after my last trip, I leave the drain valve cracked open on the way home to ensure any water has a way to escape.

Our last trip is still over a month away.

Happy future Retirement
