What is a backflow?

A backflow is the detrimental reverse of water flow in your plumbing or sewer system. To cite and example, there may come a time when sewage comes right out of your drains even when it’s supposed to go straight to your septic tank or the public sewer. Instead of going the right direction, wastewater comes out of your drain pipes again. What’s not good about this is not the presence of dirty water but the possibility that your clean water lines may get contaminated.

Such a problem occurs in cross-connections or the parts of your plumbing system where the clean water and drainage lines meet or join. And when you potable water gets contaminated, you’ll have to worry about your health. Sewage contains different waste particles and bacteria that may put your lives at risk. Examples of these include protozoa and amoeba. Waterborne diseases and parasitic infections like cholera and dysentery are acquired from dirty water.

What causes backflows?

Backflows result from backpressure or back siphonage. Back siphonage occurs when there’s a sudden reduction in water pressure in the potable water lines. For example, when fire fighters make use of a hydrant to stop a fire, there’s an unexpected drop in water pressure in the clean water lines. Another example is when a water line breaks. In these situations, the flow of water in the system may actually reverse and create some kind of a suction effect. This suction effect will then lure the swage out of the drainage lines and into the clean water supply lines.

Another sample situation is when the water pressure in a sewage or drainage line exceeds the water pressure in potable water systems. This usually happens in systems that have acid, soap or antifreeze. Since the pressure in the drainage system is greater than the pressure in the potable water system, the sewage is forced out of the pipe.
