What good are low point drains?

just fill then with antifreeze. the drains are good to get rid of the antifreeze next spring.

If you don't have them how are you going to drain the tank. They will be fine and won't break

Do you really think the other 1000's of RV's also need to get rid of their low point drains? Every type of RV has a low point drains.
Do you think you just discovered a flaw:h.
Winterize as normal they won't freeze.
Cracks/breaks happen due to expansion. That little nub of pipe has room to expand if it drop to below 32º briefly overnight.
It's really nothing to worry about

“I see the purpose of low point drains for folks that winterize just by blowing out with no antifreeze”

No, you don’t see the purpose. How do you propose folks fully drain their freshwater tank after using bleach to sanitize? As the “lowest” point, that’s where the nastiest water and other stuff is located.

I'm speaking of two pipes, one hot water, one cold water, that are tapped into lines running along under the water heater, that protrude down 10" under the bottom of the trailer, and are labeled low point drains. I also have a single line from the bottom of the fresh water tank used to drain it. The fresh drain is crossed link flexible PEX. It should handle some freezing. The low point drains are hard plastic probably not going to handle freezing. And, sticking out 10", I don't believe that they would not freeze down close to zero degrees. My concern is how do I prevent freezing and busting when I'm still camping in weather between zero and 32 degrees. I don't have a problem once the trailer is parked for winter full of antifreeze. Eliminating them eliminates busting from freezing, and I don't see why I need them to fill the system with antifreeze.

If you remove the drains, how will you drain your system and get rid of the antifreeze in the system?

Seems like there is some confusion about the difference between low point drains and fresh water tank drain.

Remove them and give it a try.

I was having the same thought on my trailer this fall, and I use air to winterized... they serve me zero purpose and are a section of water line outside the headed envelope of my trailer. Defiantly not needed on my setup, and I struggle to see where they are a benefit if using air to blow out water lines. Maybe they have a use when using antifreeze (yuck) to winterize.

You all too mean! LOL

Just put a sleeve of foam, like the ones you put on your pipes sticking out the ground for those leaving in harsh winter countries.

Everyone who said it's alright are right -- but then putting sleeves will assuage you of your worries and you'll have better sleep at the dead of sub-freezing weather camping out.
