Where are BPAs located?
BPAs are most often found on a location’s main service line where they prevent on-site contaminants from polluting the public supply of drinking water. They are also found at various locations within a building to protect the building’s occupants from contamination in one part of the building from affecting the water supply throughout the building. A very common application is to use a BPA to protect the drinking water in a building from the tainted water contained in the fire sprinkler system.
