First winter for my van. Is it ok to blow out the water lines with a compressor and not add that pink fluid? I removed toilet and capped black sewer line, capped water line that was used to flush toilet, and will never use the shower. Basically, all I have is running water in the kitchen sink, hot and cold. I know if have to drain the hot water tank. There is a black tank and a grey tank, black tank no longer used. Appreciate any assistance!

The pink will absorb moisture rather than let it pool. I'd use it.

 

Thank you, I will use the pink antifreeze. Can I ask you something else? Should I fill the propane tank for winter or leave it empty? The answers I am seeing online say to fill it for winter but I'm not sure that's correct.

 

Propane is often cheaper in warm weather with less demand. You can fill it or not. It's up to you. There isn't any water in there is it was purged properly. I'd fill it in case you need it during the winter.
