Pacific Backflow Warns San Diego Property Owners: Winter Weather Increases Backflow Risks
SAN DIEGO, CA, UNITED STATES, October 23, 2025 /EINPresswire.com/ -- As San Diego heads into the winter months, Pacific Backflow, the region’s trusted backflow prevention and testing specialist, is urging homeowners, HOAs, and commercial property managers to inspect and certify their backflow systems now—before colder weather and seasonal rains compromise water safety.
While Southern California is known for its mild climate, winter remains one of the most dangerous seasons for backflow incidents due to increased rainfall, water pressure fluctuations, and irrigation system inactivity.
According to data from the City of San Diego Public Utilities Department, the region experienced over 500 reported cross-connection or backflow incidents between 2022 and 2024. The majority occurred between November and February, coinciding with seasonal irrigation shutdowns and stormwater pressure changes.
“Backflow doesn’t just happen during major storms—it often occurs when property owners least expect it. When irrigation systems are shut off for winter or heavy rains alter pressure zones, that’s when contaminants can reverse-flow into the public water supply. Preventive testing is the only way to stop that from happening.”
Backflow events can allow pesticides, fertilizers, bacteria, and industrial chemicals to enter potable water lines, putting communities and businesses at risk. Many property owners are unaware that annual testing is mandated by state and local law, with fines for noncompliance ranging from $100 to $1,000 per incident.
