Backflow Prevention

50 Any Service_Banner

Do you know what a backflow device is? Do you even know what the term “backflow” refers to? It’s okay if you don’t, but all of us here at Lake Cook Plumbing, your local Buffalo Grove and Suburban Chicago plumbing experts, want you to be fully aware.

When a water line connects with pipes containing a non-potable substance – like sewage water, for example – it’s considered “cross connection.” Backflow is when your water becomes contaminated as it flows through a cross-connection from a non-potable source into the drinking water line.

A backflow device will ensure that drain water never makes it into your drinking water. If you have a lawn watering or irrigation system, having one of these devices is mandated by state law. So, if you find yourself without one, look no further than Lake Cook Plumbing!


More Information on Backflow

Backflow is water flowing in the opposite direction than it’s supposed to. When hydraulic conditions within any water system stray from the norm, the direction of water flow can be reversed. This creates a backflow condition and the potential for contaminates to get into the water you and your family drink. Our backflow prevention technicians are expertly trained to keep clean and drinkable water flowing directly to your home.


How Does Backflow Happen?

There are two different ways you can see backflow occur – through back siphonage or back pressure. Back siphonage occurs when the water pressure in your plumbing suddenly drops from fire fighting or a water main beak. During an extreme water pressure reduction, it’s possible for the water flow in your pipes to become reversed. This reversal can create a suction effect which draws the contaminants to your drinking water pipes.

Back pressure, on the other hand, occurs when the pressure in your pipes surpasses the pressure in the potable system that provides the make-up water. This, then, forces the drinking water to reverse the direction of its flow through the cross-connection between both systems. Much like back siphonage, this reversal causes contaminates to enter the drinking water system.
