What is the purpose of low point drains?

New camper we bought has low point drains under the camper for both the hot and cold lines.

I assume this is for draining the water system, is this a good enough method for winterizing? Is it just for winterizing if you are caught off guard and don't have any antifreeze?

Just wondering exactly what the purpose of these are.

Thanks!

  • If all the plumbing was sloped towards the low point with absolutely no sags, then maybe it would work. But RV's are built any which way and you can't count on draining properly.
  • They are for draining the water out of the system at that low point. You'll still need to close them after draining and either blow the lines out with air or winterize with RV anti-freeze. I prefer the anti-freeze method. Your choice though depending on how much risk you're willing to take.
