Our low was 19 this morning about 8AM. That's the lowest since 1996 for the Houston area. I saw a friends post on social media. His truck was indicating 16 deg as he was heading in to work. Glad I am not that guy. He is a lineman for CenterPoint Energy. The good thing is, he is a supervisor so maybe he got to sit in the truck.
We had one pipe plug (freeze) overnight but it has since thawed out. It was on the north wall of the house and supplies water to the toilet. I may have to set an alarm and get up and flush it a couple of ties during the night. Low for tonight is forecast for 22 degF.
If the cold was going to continue for more than just tonight, I could shut the water of to the house via a valve located in the wall in the garage. All outside pipes/water faucets are insulated and wrapped.
That's my story and I'm stickin' to it!
