Fun Fact Friday: Backflow Preventers
What is a Backflow Preventer?
A backflow preventer is a safety device that stops contaminated water from flowing backward into a potable (safe to drink) water supply system.
Did you know that back in 1933, a backflow disaster at the Chicago World's Fair, caused widespread illness from a contaminated water supply, which highlighted the dangers of backflow and led to the creation of plumbing codes requiring backflow prevention.
Since 1974 when the Safe Drinking Water Act (SDWA) was passed, Backflow preventers have been required. Establishing the requirement to eliminate or protect cross-connections to safeguard drinking water.
Today Louisiana laws and regulations require buildings with backflow prevention to have the system tested and inspected once a year by a licensed professional, per NFPA25.
