What is the primary goal of backflow prevention?

The primary goal of backflow prevention is to protect drinking water from contamination. This is essential because backflow can cause non-potable water or other contaminants to flow back into the potable water supply, posing serious health risks to the public. The mechanisms in place for backflow prevention help ensure that there are barriers preventing any potential contamination, thereby maintaining the safety and quality of drinking water.

The need for this protective measure stems from various factors, including changes in pressure within the water system, which can lead to back siphonage or back pressure scenarios. By effectively preventing these occurrences, backflow prevention devices play a critical role in safeguarding public health.

While cost reduction in pipe installation, maintenance of valves, and improving water taste are important considerations in water distribution systems, they do not represent the primary objective of backflow prevention efforts. The main focus is always on ensuring that the water consumed is safe and free from any harmful contaminants.
