Backflow Testing, and Why It's Important

Understanding What Backflow and Backflow Testing Is

Fresh, safe drinking water is now so ubiquitous that most people don’t understand everything that goes into protecting treated water. The plumbing infrastructure for transporting clean water is designed to keep water safe. 

If certain components of the plumbing system, such as backflow prevention devices, are damaged, the clean water within the pipes could be subjected to contamination called backflow, which could lead to serious health problems. Backflow prevention devices are essential but must be professionally tested to ensure they can prevent backflow and protect the water supply. Here is a short guide to backflow and backflow testing. 

Dangers Associated With Backflow 

One of the essential features of plumbing is that water only flows in one direction. However, when large pressure changes occur, water can siphon backward through pipes, causing backflow. If backflow prevention devices aren’t present and operational, the siphon can pull dirty, contaminated water or pollutants back into freshwater piping. 

Some of the contaminants that people can be exposed to due to backflow are fertilizer, dangerous chemicals, biohazardous waste, and more. Backflow is an extreme health hazard since it can cause people to use contaminated water for drinking, cooking, or bathing, leading to diseases and illnesses.

How Does Backflow Testing Help Prevent Backflow?

Plumbing codes have come a long way in preventing backflow. Codes requiring backflow preventers, such as vacuum breakers and air gaps, diminish the chances of backflow occurring. However, it’s essential backflow testing is done routinely to check that backflow prevention devices still work. 

Some backflow preventers, like an air gap, prevent backflow by creating a separation between the water supply and the start of the sewer system, while some work by sensing small fluctuations in water pressure. When water is sensed to be flowing backward, the backflow prevention device stops the flow of water. Since these devices are critical for public health, they must be professionally inspected and tested annually to ensure reliable operation. 

Importance of Testing Backflow Devices 

Water is one of the most essential nutrients for human life. Backflow prevention devices play a critical role in preventing water from becoming contaminated. Backflow testing offers several benefits, including ensuring the safety of the water supply, protecting public health, and meeting plumbing code requirements. 

By regularly testing backflow preventers, homeowners and businesses can help prevent the backflow of contaminated water into the freshwater supply, reducing the risk of diseases and illnesses. Additionally, it can help identify and address any issues with backflow prevention devices before backflow occurs, allowing for prompt repairs or replacements and ensuring a safe water supply for everyone.
