Blowing Out Rv Water Lines With Air

I helped him do his.

Blowing out rv water lines with air. It can t do this because the pump has internal valves to prevent backflow and is. Rvs have low point drains in their water system. I do not recommend you just antifreeze and skip blowing out your system. Antifreeze comes after you have blown out all the water you can.

You simply need to remove the small amount of water that remains after gravity draining your water lines. When using an air compressor to winterize you don t need to blow out the water with force. Prequel to my other winterizing video. Pick one that also has an adjustable pressure gauge so you can control how much air gets pumped into the rv.

That s where antifreeze comes in. Smaller compressors are fine for winterizing your rv. Set your air compressor to 30 psi with a maximum air pressure of 50 psi and start blowing air into the water inlet. Remember to flush the.

And no messing around come spring. There are various ways to ensure you have no water in your lines. The compressed air does not blow out the water that is inside the water pump. I learned how to do this by a kind gent at our regular campsite.

Get a portable air compressor to blow air into the water lines. By opening these drains most of the water in the system will drain out by gravity. 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. Compressed air does push most of the water out of the lines but not all.

One way is via a small pump that pushes rv antifreeze through everything. We ll still need a couple of gallons of rv anti freeze specifi. 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.

Filling the water lines with rv antifreeze you should still blow out the water lines with your air compressor first. At the very least open all of the faucets and the shower to drain away as much water as possible. Rv plumbing has many up and downs as it runs through various cabinets and over various obstacles and the water that collects at these places will freeze. Clean and flush your black and gray water tanks drain the fresh water tank completely then close the drain valves.

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. It s clean and quick. I mentioned above that blowing water out of rv lines cannot be done 100 percent using air. Pour one quart of special rv antifreeze into the gray and black tanks to protect the drain valves and seals.

You will need to use at least 2gallons or more of rv antifreeze to full all of your water lines. My way is blowing out the lines using an air compressor.
