Winterizing with compressed air has nothing to do with the p-traps. The author conflates the two. The compressed air clears the water lines. RV antifreeze protects the p-traps. It's not either/or.

Better yet........GO SOUTH! Ah.....forget I said that! I do like the emptiness in the south so far this season!

I typically take the extra step to blow out the lines first. That way as soon as pink starts coming out of the faucet, it is near/at full strength. Otherwise, the first few seconds of pink are diluted, so you will either have less protection, or will run it out the faucet longer and use more. Of course always remember to put several ounces down the drains - something just blowing out the supply lines does not address.

I remove the main water filter in the wet bay, make sure fresh water, grey and black tanks are empty, drain the water heater and then blow out my lines with compressed air. I cycle through all the faucets until no air comes out. Then I do the following
1. disconnect the shower head, kitchen sink head and the sprayer head for the toilet.
2. I remove the water line from the fridge and then go inside and remove the (2) water lines feeding the water and ice in the door as well as remove the internal fridge filter.
3. I disconnect the lines from my water pump. My pump os very easy to reach.
4. I turn on all fauces and leave them open. Don't forget the one in the wet bay.
5. I pour antifreeze in all p-traps and add some to the toilet bowl.

I do not put any antifreeze in the water system only the drains. I do not want the antifreeze taste in our water as believe it or not we use our water for cooking and drinking. Our water is triple filtered and always tastes fine. We do sanitize the tanks as well.

Do you put antifreeze in the bottom of your black and grey tanks?

Do you put antifreeze in the bottom of your black and grey tanks?

If they're both emptied to the point that nothing is draining to the discharges there's nothing any liquid remaing on the bottom of a tank could harm were it to freeze. The antifreeze if there were enough would would run to the blade valves which in any case wouldn't necessarily be a bad thing.
