How backflow occurs

 How backflow occurs

Backflow conditions exist in two forms:
 
Backsiphonage occurs when the water pressure drops in the water supply system, associated with high demand conditions, main breaks, firefighting, or construction activities. When pressure in the water supply system drops, water from the customer’s system (and potential contaminants) are sucked into the main water distribution system.
 
Backpressure occurs when pressure in a customer’s plumbing system exceeds the supply system pressure and forces water (and potential contaminants) into the water supply system. Increases in pressure can be generated by pump, elevation of piping, heating applications, or steam or air pressure.
