Blow Lines or AntiFreeze, or both?
I've read a lot of threads about winterization. Some say blow the lines, some say fill the lines with antifreeze. But I still have a few questions. I'm sure I'll get a number of opinions, but I fig...

If done correctly either way works well.
Blowing out the lines just seems to be easier and quicker for me. I can blow out the lines and winterize in about 15 to 20 minutes. Could do it much quicker before I had a W/D. I have a portable commpressor and I can winterize and de-winterize on the road. Don't forget to drain your hot water heater
The advantage of blowing out the lines is you don't have that yucky stuff in your water lines. Every spring check out the posts about water still tastes funny after flushing RVantifreeze out. No matter what you read air does't freeze and not enought moisture in lines to hurt anything.
I use a regulator on my compressor To keep pressure below 45 pounds. Plus I always have one water valve open all the time during the process. Open 2nd valve then close the 1st valve.
W/D: I disconnect the water lines from the washer and blow out those valves/lines the same way. I pour about 1/2 gallon of antifreeze in my Washer and turn it on and spin it out. That antifreeze will fill the washer drain trap
I pour antifreeze in all the drains. Make sure it is enough so some goes down into the grey tank and keeps the grey dump valve moist.
Don't forget to open toilet flush valve so that also gets blown out & also outside shower valve if you have one. If you have a water filter remove the filter housing because water will drain back into it. I also add some antifreeze to black tank to keep black tank dump valve moist. Then add some to toilet bowl.
Works for me. We get chilly in NW WY and no problem with blowing out lines. Down to 20F this morning. We will get down to 25 to 30 below in the winter.
