Hello everyone – in this video, I show you how I winterize our RV, Das Bus. We go out frequently in the winter, so I came up with this sequence of steps. There are a few caveats though. First, I wouldn’t call it “completely” winterized. It’s thorough enough that no damage occurs when it gets below freezing, but I don’t do things like take the batteries out and put them in the garage – or cover the AC unit. And the second caveat is that you’ll need a good, high-volume air compressor to do it this way.
Pay Attention to your Air Source!
The inside of an air compressor can be a nasty place – rust, oil, and condensation can all find their way into your compressed air. And if you’re going to use it to winterize, that means they can find their way into your water system, which probably isn’t what you want. The compressed air in my shop is dried and filtered, and I maintain the compressor regularly. If your compressed air isn’t clean, then you’ll need to consider other ways to winterize. Scuba divers don’t fill their tanks from just any compressor, and you should take just as much care with your water system.
But the most important thing for me is how quickly it goes, and how quickly I can get her going again when we head out next. I’ve laid out the steps in order below, and you can see me run through them all in the video:
1. Empty fridge, take anything else in that might freeze or spoil
2. Drain fresh water tank from valve inside – close valve
3. Connect city water and fill grey and black tanks to 90%
4. Disconnect city water
5. Drain water heater and close back up
6. Engage water heater bypass
7. Set air pressure regulator on compressor to 45 psi
8. Connect compressed air to city water
9. Open each faucet, one at a time, including toilet, until they run dry
10. Disconnect compressed air
11. Verify whole-house filter is empty
12. Head to dump
13. RV antifreeze down all traps and some in toilet to cover seal
14. Take batteries out of smoke detector
15. Kill power at battery cutoff switch
16. Cover windows
Nothing revolutionary, but it may help you. Enjoy!
