What Causes Backflow in Commercial Plumbing? 

Robinson & Son Plumbing & Mechanical Explores the Reasons for Backflow   

Many clients wonder what causes backflow in commercial plumbing. Backflow occurs when water flows in the opposite direction, contaminating clean water with pollutants. In commercial plumbing, backflow often results from a sudden drop in water pressure. This creates a vacuum that draws contaminated water into the potable water supply.

Such a vacuum can happen when using a large quantity of water quickly, such as during a fire or when a main line breaks. Other causes include cross-connections between potable and non-potable water sources and poorly maintained backflow prevention devices. 


The Risks of Backflow in Commercial Plumbing 

The risks associated with backflow are serious. Contaminated water can contain chemicals, bacteria, and other harmful substances. This can lead to health risks, like waterborne diseases, for employees and customers in commercial settings.   

Businesses such as restaurants, hospitals, and schools face significant liability if backflow occurs, potentially causing illness or even legal repercussions. Additionally, backflow can damage plumbing systems, leading to costly repairs and downtime, which can impact a business’s bottom line. 


Effective Backflow Prevention Strategies 

Preventing backflow in commercial plumbing requires a proactive approach. Installing backflow prevention devices, such as reduced pressure zone (RPZ) valves or double-check valves, is the first line of defense. These devices prevent contaminated water from entering the clean water supply, even during a sudden drop in pressure.  

Regular maintenance and annual testing by certified professionals are essential to ensure these devices function properly. Businesses should also establish cross-connection control programs to identify and cut potential risks.
