What Are Some Common Causes Of Backflow?

Backflow is a plumbing issue that can cause contaminated water to flow backward into your clean water supply. This is a serious issue that can put people’s health at risk. The good news is that backflow can be prevented with professional installation and regular testing. Read on to learn more about what causes backflow, why it’s so important, and how you can protect your property from this hazard. 

Back Pressure 

Back pressure is one of the most common causes of backflow. It occurs when a piece of equipment in your home or business generates more pressure than the water distribution main. Usually, it’s caused by heat expansion from a boiler, but it can also be the result of high pressure from fire sprinklers or pump systems. This pressure can cause an undesirable contaminant to enter your potable water supply. If this happens, it could lead to serious health consequences. Backflow prevention is the key to preventing this type of contamination from entering your system. It’s a simple yet effective way to safeguard your family’s health and safety. 

Back Siphonage 

Back siphonage occurs when the pressure in a pipe drops to atmospheric or below, creating a vacuum. During times of high demand from firefighting, a water main break or customer demand during a heat wave, a vacuum can cause foreign items to be sucked into the water supply. Back siphonage can contaminate clean, potable water with pollutants that can make residents moderately to severely ill. These contaminants can include pesticides, chemicals, sewage and more. 


Backflow can occur when contaminated water from one system, such as a laundromat or irrigation system, is introduced into another system, such as your home’s drinking water supply. A common cause of this is chemicals, which can be in a liquid form or in powder form. When the backflow preventer does not work properly, contaminants such as pesticides, herbicides, and other chemicals can enter your drinking water system. These chemicals can then contaminate your family’s water supply, leading to health problems.
