The Problem

Backflow theft is an epidemic

Thieves steal backflow preventers for $40-$250 in scrap copper. Property owners pay $3,000-$10,000 to replace them. It happens overnight, often repeatedly. Cities are mandating protection. The math is simple: a $300-$600 cage prevents thousands in losses.
