Backflow Testing: What is It and Why is It Necessary?

 

Here at Best Plumbing, we offer services to help with all of your residential and commercial plumbing needs. Backflow prevention and testing is a necessity for apartment and condominium buildings, restaurants, and other public places. Local municipal codes often require annual backflow testing, so if your property or business needs professional help, call Best Plumbing! We provide backflow prevention devices and testing in the greater Seattle area.

 

What is Backflow?

Backflow is contaminated water that has reversed flow, thereby entering clean water lines to homes and businesses. This is typically caused by a significant change in water pressure, from a burst water main, frozen pipe, or unexpectedly high demand on the water system. Backflow can occur at any cross-connection between clean and dirty water in residential, commercial, or industrial water lines. Backflow may contain hazardous materials like human waste, pesticides, or chemicals, so it poses a serious health concern.

 

Backflow Prevention and Testing

To safeguard against backflow, a backflow prevention device may be installed. In the case of an unexpected or dramatic change in water pressure, this device will prevent backflow from entering the clean water supply. However, it is important that this device is properly installed and tested to ensure that the clean water line remains free of contaminants.

Municipal codes require annual testing of backflow prevention devices to ensure that they are functioning properly. If testing is not completed on time, your property or business’ water supply might be interrupted and you may be fined. That is why we recommend scheduling backflow testing well ahead of time.

Fortunately, Best Plumbing is here to help! We provide a variety of backflow-related services in Seattle and Bellevue, including backflow prevention device installation and testing. Call us to schedule testing for your business or property.
