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 anythin...

I use my low point drain lines to empty the hot water tank so I don't have to remove the plug every time I want to drain the tank when not in use.
You just have to open the pressure relief valve and open the low point drains and you get pretty much all the 6 gallons of water out of the HWT.
I blow out my lines and don't use the RV AF. I made an adapter that screws into the city water inlet with a ball valve on it and hook it to my air compressor and set the compressor to around 40 psi and just go round and round on the faucets, toilet, pump, shower, outside shower, etc and open hot cold let it build pressure back up, repeat until I'm satisfied that I've got the water out of the lines. I also close and open the low point drains too, so it just all works for me..
I can see your point on the low point drains if you are in 0 degree weather and have water in the system.. Mine are exposed under the trailer too, so in theory, they would freeze up at the end.. Would they freeze up enough to split the pipes? Dunno.. For me, that's a non issue, as I don't camp in that kind of weather... But I know there are a lot of folks that do camp/live in freezing weather, so I guess that would be a concern..
Not real answer for ya, other than to say "good luck".. :)
