You should see some more water drain from the water heater and hear the air entering it. With the water heater bypassed its time to blow air out of the hot water lines. Now close the warm water and open the cold water side and use your air compressor to blow out water on this side.
How to winterize a travel trailer by blowing out the lines. Good golly, I could have burst my travel trailer plumbing system due to freezing! I had forgotten to drain the the water lines and no one needs pipes to freeze and burst. Here is how to winterize a travel trailer by blowing out the lines with compressed air, alleviating the need for gallons of antifreeze through your drinking lines!
Connect the “Blow out plug” to the city water inlet-not the fresh water tank. If you use the water pump, you’ll need to install a pump bypass kit if it’s not already equipped since it draws from the RV’s fresh water tank and you don’t want antifreeze in there. The only difference is that the water pump bypass valve is used to draw RV antifreeze into the pump and distribute it throughout the water system.

What size air compressor do I need to winterize my RV?
Volume – not pressure – is what you need. A 20 gallon air compressor is probably more than you’ll need to simply winterize an RV. If you’ve got one that large, it will work fine, but others use much smaller compressors.
What air pressure should I use to winterize my RV?
Your rig should have low-point drains on all the water lines — when you open them, gravity will remove most of the water for you. But when winterizing an RV, what you really need is air volume, not air pressure. You’ll only be blowing out your lines at 35-50 psi — any higher may damage your plumbing.
Can you winterize RV without antifreeze?
No matter what your reason might be for winterizing your RV sans antifreeze, the process is the same. The goal with this winterization method is to remove as much water as possible from the lines and tanks. This is done using an air compressor to blow the lines out after emptying all tanks.
Do you have to use antifreeze to winterize an RV?
What is this? So, antifreeze is not only used for storing an RV in cold winter climates, but also for using it. RV antifreeze is readily available, and can be used to winterize an RV that will be used for cold-weather camping.

How long does it have to be below freezing for RV pipes to freeze?
In general, the temperature has to dip below freezing (32 F) for approximately 24 hours for RV pipes to freeze. This is all dependent on many factors such as if you have an enclosed underbelly, heated underbelly, heat tape, insulation, or other preventative measures in place.
What temp should you winterize RV?

Is blowing out RV water lines vs antifreeze?
