Winterizing with Air this time
As the summer is winding down and students are going back to school in a few weeks, I am thinking about trying a new process for winterizing my trailer. I have been using the Antifreeze in the pipes ...

Best write up I've seen and works like a check list, so I follow this one. Change to your situation. I follow pretty closely but have to include the outdoor shower wand.

1. Drain the fresh water tank. Leave the **** open.
2. Remove the plug on the HWH tank. Leave it in the compartment. Close the compartment door.
3. Bypass the HWH (in and out closed, crossfeed open).
4. Run the fresh water pump and open all faucets until no more water comes out.
5. Shut the fresh water pump off.
6. Apply 50 PSI air to the lines.
7. Open the low point drains and allow the water to drain out until you get just air.
8. Close the low points to allow pressure to re-build.
9. Run upstairs and open each faucet, one valve at a time, first cold, then hot. Allow the water to run out until you get nothing but air.
10. Do all the faucets in this fashion, closing them up as you go from one valve to the next.
11. Do the toilet last. Put your foot on the pedal until it is just air coming out.
12. Repeat again for all the faucets (kitchen, bathroom, shower) and the toilet.
13. Leave the shower wand on the shower floor to drain.
14. Remove pressurized air from the system.
15. Open the low points.
16. Open all the faucets.
You're done.
I winterize at least 50 motorhomes each year using this exact process and I've never had any freeze related damage, ever. I don't routinely use any of the pink stuff, but occasionally if I have some laying around, I will pour a little bit down into each drain and a little down the toilet. I've done the p-traps and potty both with anti-freeze and without with no ill effects either way. And this is in Chicago weather which is in a deep freeze from December thru March. I don't personally like to store any motorhome with any substance in the lines. Lines filled with air will never freeze. Lines filled with anti-freeze and water....well, how do you know for sure what concentration of water:anti-freeze you have? For me, it's just too much of a risk. I know for sure that air doesn't freeze.
