Understanding Backflow Prevention

To ensure the safety of our water supply, it is crucial to understand the concept of backflow and the importance of backflow prevention. This is where RPZ testing plays a vital role.

What is Backflow?

Backflow occurs when the flow of water in a plumbing system reverses, allowing non-potable water or contaminants to enter the clean water supply. This can happen due to changes in water pressure, such as a drop in supply pressure or an increase in downstream pressure. Backflow can lead to the contamination of drinking water, posing serious health risks to individuals.

Importance of Backflow Prevention

Backflow prevention is of utmost importance to protect the integrity of our water supply. By implementing backflow prevention devices, we can prevent the reverse flow of water and contaminants into the clean water system. These devices act as barriers and ensure that water flows in only one direction, safeguarding the potable water supply from potential pollutants or hazardous substances.
