As temperatures dip below 32°F, it’s important to winterize any exposed plumbing connected to your backflow preventer. Freezing conditions can cause serious damage to the backflow preventer and its internal components.

Cornerstone Mechanical can ensure your device is properly protected this winter! Call to schedule your appointment!
