What is backflow prevention?

Backflow prevention is a critical measure designed to protect the public water supply from contamination. This process involves using various devices and methods to ensure that water flows in only one direction and does not inadvertently flow back into the distribution system, which could happen due to changes in pressure or other factors. When water is drawn back into the system, it can carry pollutants and contaminants from its source, which poses serious health risks.

The goal of backflow prevention is to maintain the integrity of the potable water supply, ensuring that it remains safe for consumption. It is essential in various settings, including residential, commercial, and industrial water systems, where potential sources of contamination are present.

While other options mentioned have their own purposes, they do not focus on the key aspect of safeguarding water quality from backflow risks. For instance, increasing water pressure, filtering water, or enhancing taste are all important for overall water system management, but they do not specifically address the prevention of contamination that backflow prevention targets.
