Breakdown of common devices like air gap systems, check valves, and reduced pressure zone devices—explaining their uses and advantages
When testing a backflow preventer, a technician is checking several key components to ensure the system is functioning properly and preventing contaminated water from flowing
There are two main types of backflow: backpressure backflow, caused by downstream pressure exceeding supply pressure, and back siphonage, caused by negative or reduced pressure
