Why Should I Be Concerned?
Backflow can be caused by mainline piping failures or unexpected loss of supply pressure. For example, it is a condition that can occur when the drinking water system pressure drops below that of a system containing unknown water quality or chemicals,drawing the questionable contents into the drinking water system.
Another instance is your lawn sprinkler system. If the water pressure suddenly drops, your drinking water may become contaminated with bacteria, chemicals, and poisons that can be siphoned back through the lawn sprinkler system piping.
