What is a potential consequence of not repairing a faulty backflow preventer?

  1. Increased water bill

  2. Contaminated potable water supply

  3. Low water pressure

  4. Reduced system efficiency

The correct answer is: Contaminated potable water supply

The potential consequence of not repairing a faulty backflow preventer is that it can lead to a contaminated potable water supply. Backflow preventers are essential devices designed to keep non-potable water or other contaminants from entering the clean water supply. When these devices malfunction, there is a risk that pollutants from irrigation systems, industrial processes, or wastewater can siphon back into the potable water lines. The integrity of the water supply is critical for public health, and contamination can lead to serious health issues for consumers who rely on that water for drinking, cooking, or personal hygiene. Therefore, ensuring that backflow preventers are functioning correctly is a vital aspect of maintaining a safe water system.
