Backflow devices are an essential part of residential and commercial plumbing systems. The primary purpose of a backflow prevention device is to keep wastewater contaminants from getting into the freshwater supply. These devices provide peace of mind when there is a drop in wastewater pressure or clean water pressure that can result in water moving in the wrong direction and causing cross-contamination. The plumbing pros at Merrimack Valley Plumbing can help you make sure that your home or office water supply is not being contaminated.

Common Causes of Backflow

The water pressure in your plumbing system is designed to prevent backflow and keep clean water and contaminated water separated. However, some factors cause a reduction in water pressure, resulting in backflow. Common causes of backflow include:

  • Extremely high demand on the system
  • Backflow preventer failure
  • Frozen pipes
  • Burst water mains

Backflow is most common in commercial buildings, but it can also occur in residential buildings, which is why it is important to install backflow devices in your home.
