Commercial irrigation systems need winterization before South Lake Tahoe temperatures drop below freezing. Worth understanding why. Water left in pipes, valves, and backflow preventers expands as it freezes. That expansion cracks components and creates expensive repairs come spring. Riley Plumbing & Heating shut down this commercial property's irrigation system, verified the backflow preventer was properly drained and protected, and documented everything for the property manager.
