How Backflow Prevention Protects Your Drinking Water


One significant advantage of receiving water via the public water system is the extensive treatment it undergoes. Before reaching your home, this water undergoes chemical treatments that eliminate many contaminants. However, even treated water can become recontaminated, particularly through backflow. Contaminated drinking water poses serious health risks to your family. That’s why MillTown offers expert backflow prevention services. By choosing our plumbing solutions, you can safeguard your water supply from harmful germs and pollutants.

Understanding Backflow: How Does It Happen?

Backflow generally occurs when there is a drop in water pressure within your home’s plumbing system. Situations like frozen pipes, a burst pipe, or using a significant amount of water simultaneously can result in reduced water pressure. This pressure drop causes the water to flow backward, potentially drawing contaminants from the municipal main into your home. Backflow can also occur if the pressure in your plumbing system exceeds that in your drinking water system. This reversal flow through a cross-connection can introduce contaminants into your potable water.

Preventing Backflow to Protect Your Water

If backflow issues are plaguing your home, we can help. Our certified professionals can install a backflow preventer. This device utilizes a specially designed valve or air gap to prevent reverse water flow effectively. These devices are crucial for maintaining cross-connections like the water main, ensuring clean water enters your system. Many municipalities mandate the installation of backflow prevention devices in homes. With four decades of plumbing expertise, MillTown can install your backflow preventer, ensuring it complies with municipal code regulations.
