What good are low point drains?

What good are low point drains on a trailer that is supposed to be good for 0 degrees? My drains are solid, slightly flexible, plastic pipe. It seems like they’re going to freeze and bust at anything close to zero degrees. I do have tank heaters, but 10” of ½” pipe hanging down in cold air seems like a problem waiting to happen. All other pipes run in heated areas. I see the purpose of low point drains for folks that winterize just by blowing out with no antifreeze. However, since I use antifreeze, I see no value in the drains along with an increased risk of freeze/bust.
1) What am I going to regret if I remove the low point drains?
2) How can I keep them from freezing until I get them removed?
Thanks
  • My last 5th wheel the low point drains had a valve up inside the trailer. I never used them but they channeled cold air up to the lines so if the line froze while winter camping I knew exactly where the problem was. Solved the problem by opening up the area so interior heat could get to them.

    My ‘15 5th wheel has two lines hanging down with caps on them. I don’t use them and so far... down to 14 degrees F have not been a problem. I’ve forgotten they are there until reading your post.
