Blowing out rv water lines with air. I learned how to do this by a kind gent at our regular campsite. By opening these drains most of the water in the system will drain out by gravity. It can t do this because the pump has internal valves to prevent backflow and is. We ll still need a couple of gallons of rv anti freeze specifi.

To keep our pipes from freezing we winterize the water lines in our rv using compressed air. Pour one quart of special rv antifreeze into the gray and black tanks to protect the drain valves and seals. And no messing around come spring. I mentioned above that blowing water out of rv lines cannot be done 100 percent using air.

When using an air compressor to winterize you don t need to blow out the water with force. Try getting one that holds at least 2 us gal 7 6 l of air so you have enough to completely flush out the lines in one go. At the very least open all of the faucets and the shower to drain away as much water as possible. That s where antifreeze comes in.

I do not recommend you just antifreeze and skip blowing out your system. One way is via a small pump that pushes rv antifreeze through everything.

Prequel to my other winterizing video. 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. When the water has been blown out then close the valve and move on to the next water opening. While your compressor is blowing air into your water lines walk around your rv and open up water valves one at a time to blow the water out from the lines.
