Draining low point water in Freezing Weather
We live in our 2007 Flagstaff Classic Super Lite full time, 95% of the water lines are inside the TT, we heat with two Dr. Infrared heaters, no propane, our TT is total electric. My question is, should l drain low point drains when it is going to be below 32 degrees for an extended time, and leave all the faucets open? Even with the temperature at 70 plus degrees in the TT the water lines are covered or under cabinets, just don't want busted water lines. What do any of you other full timers do, or any advice do y'all have?
