I live in Las Vegas, and we are just now getting into the season when we can use our TT most weekends (Summer necessitates a 5 hour drive to the nearest mountains to escape the heat). My question is how cold does it have to get before I need to worry about blowing out the lines? We get occasional cold fronts that will drop the temperatures into the mid 20's for 5-6 hours. I know that that's enough to ruin pool pumps and outdoor irrigation systems that aren't covered. How cold does it have to be before I need to worry about blowing out my lines and pouring antifreeze down my p traps?
