But this time, it’s a very different story than what we saw during the big freeze five years ago. What they're saying:Since Saturday, the Austin Fire Department reported responding to more than 90 calls for broken pipes. A local sprinkler fitter for fire protection systems said he has seen progress since 2021. "We had about 280 out of 450 properties down here five years ago, and we only received about 20 calls for service this week," Sprinkler fitter Tray Davenport said. "Most of the apartment complexes seem like they've at least made more effort to do a winterization type service," Davenport said.
