Also put a cup of RV antifreeze in each trap after draining black and grey tanks.
Blowing out the lines with an air compressor is much easier than filling all the lines with RV antifreeze and then having to flush it clean again.
This is sensible advice. I think you should take it.
All the other suggestions about using heat will work if you can get the heat into EVERY SINGLE place where there is water.
I have changed a tank that split open because it froze. Itís a lot more difficult than blowing out the water lines and draining the tanks. I was new to RVing then and havenít made that mistake again.
I guarantee that if a pipe, or even worse, a tank, freezes, you will regret that you didnít spend the hour or so that it would have taken you to winterize your rig.
