What is a backflow device and why do I need one?
A backflow device stops water from traveling backwards, caused by Backpressure (higher pressure on the customer side of the meter) or Backsiphonage (low pressure on the City side of the meter). Backflow devices are required by City Ordinance and Federal regulation where a potential hazard exists (on the customer side of the meter) which could cause contaminants to come into contact with the city water supply. Some examples of potential hazards are: chemical injection, chemical manufacturing and handling, gasoline storage, exterminators, food preparation, automatic car washes, greenhouses and nurseries, laboratories, irrigation systems, swimming pools, but there are many more not listed here.
