We were backing out of the driveway, taking off into town yesterday when my son piped up, “Mom, it’s 1 degree out! It’s nearly ready to snow, right?!”
Yes, son, it’s nearly ready to snow. And good golly, I could have busted my travel trailer! I had forgotten to drain the the water lines and no one needs pipes to freeze and burst.
So I’m going to show you how to winterize an rv by blowing out the lines. Many had expressed interest in how to care for one of these
beasts trailers, so here’s the scoop about how to do this feat with no yukky antifreeze in the lines. Ready to impress your friends, family and even spouse with your newfound knowledge? 🙂
How to winterize an rv by blowing out the lines
Every winter before it freezes, it’s important to winterize any trailer that has running water capabilities. For if you don’t, the pipes or the hot water tank could expand and burst from the ice. This causes all kinds of fun for those that repair these things.
There are various ways to ensure you have no water in your lines. One way is via a small pump that pushes RV antifreeze through everything. The con with that is you have to flush out your system really well come spring so you don’t end up digesting antifreeze in your drinking water. No like.
My way is blowing out the lines, using an air compressor. It’s clean and quick! And no messing around come spring. I learned how to do this by a kind gent at our regular campsite. I helped him do his so I could do mine when I got home.

You will need an air compressor to do this. (Amazon affiliate link)
And a blow out plug. (Amazon affiliate link)
1. Crank your compressor pressure down to 30-40 PSI.
2. Drain your water tank first. And any other water holding tanks you may have. Then close them again.
Tip. DO close them again unless you wish to wear all the water. It’s no fun getting soaked when it’s near zero degrees out and you’re on your way to town right after. (oops)
2. Attach the blow out plug to your water intake valve.
3. Have someone go inside the trailer and turn off every tap except the one closest to where you are. This would likely be the kitchen sink. Have them turn on just the hot or cold and to yell and let you know when the water has stopped running.
4. Using the air compressor, blow air through the blow out valve with a tire pump tip, until you hear the yell.
5. Have them turn off the one side and turn on the other side. Repeat.
6. Once water has stopped running, turn off that sink, and move to the next closest, and repeat. Do this with every tap, including the toilet lever.
Take some breaks rather than push the air through all at once. It’s easier on the lines. And your fa-reeeeezing hands.
Leave your socket where the hot water tank drain resides. Just leave it there. Year around. It sure beats tripping over crap in your garage, and going through 5082 sockets trying to find one that fits!
7. Pour some antifreeze down each drain, and into the toilet tank. Then leave some in the toilet bowl for good measure.
8. You are done! And are free to change your wet shoes and head into town.
And here’s why it was a VERY good idea to delay our trip to town. An icicle transpired the very next AM!
Why I don’t do this when it’s warm and lovely out in September, I’ll never know.
Now, for pure entertainment value, I’d like to draw one thing to your attention because this is slick. See how parallel the trailer is lined up along the edge of that concrete pad?
I have this ‘thing’ for straight. It has to be straight or I get itchy. I backed that guy into that tight little area on my own and got it that straight. It may have taken me a few (30ish) minutes, but it’s straight!
But there’s a trick to that too, of course. Want to know the secret to backing up a trailer straight?

Kinda makes you want to go camping again, doesn’t it?
