Hello. I have always paid to winterized my RV but would really like to learn how to do it myself without just pouring antifreeze down the toilet and sinks. I would really like to use air on the lin...

I think both methods work if done properly. However anti freeze is foolproof with less chance for error and for the most part quicker.
To the guys that use the blowout method do you sanitize your water lines in the Spring?
Is the advantage to using the blowout method that there's simply no anti freeze to deal with? Is it the cost savings?
At the end of the day I want the most foolproof method.
No it's not. I always had that additude and never had one problem over many years, until last year. Done it the same way I always have, opened the low points and drained first, then added the red pop. Last year we had a line break over the winter at the water heater area. I ran at least 5 gallons thru our lines.
I think what the situation is (was) you must get red pop thru every line. The one that didn't get any was the city water connection as I didn't have a way to get red pop thru that. Whether that is the reason water got to were it did and caused the issue, I don't know. But that is the only reason I can think of other than the line was suspect all along and the red pop got slushy and swelled a little which edged a existing problem on its way.
So for what I saved from having the dealer winterize it I paid in repairs to get it fixed. General RV by us guarantees their winterization. If it leaks they pay for the repair. I'll let them do it from now on. I'd hate to have a line split in a area I couldn't get to.
IMHO either way works. You just better be confident all the lines are clear of water.
