Causes of Backflow

1. Backpressure: Occurs when the pressure in the plumbing system exceeds the pressure in the water supply, often due to pumps or heating systems.
2. Backsiphonage: Happens when a sudden drop in water pressure creates a vacuum, pulling contaminated water into the clean supply.

The Health Risks of Backflow

Contaminated water can introduce harmful substances, including:

• Chemicals: Fertilizers, pesticides, or industrial waste.
• Biological Contaminants: Bacteria, viruses, and other pathogens.
• Heavy Metals: Lead, mercury, or other toxic elements.

Exposure to these contaminants can lead to severe health issues, ranging from gastrointestinal illnesses to long-term health conditions. - Call for after hours plumbing services in Millbrook NC

How Backflow Prevention Devices Work

Backflow prevention devices are designed to stop the reverse flow of water, ensuring the clean water supply remains uncontaminated. Common devices include:

1. Check Valves

These valves allow water to flow in one direction only, automatically closing to prevent backflow.

2. Reduced Pressure Zone (RPZ) Valves

RPZ valves are used in high-risk systems to create a barrier between potable and contaminated water. They feature two check valves and a relief valve for maximum protection.

3. Air Gaps

An air gap is a physical separation between the water outlet and the flood level of the fixture, preventing water from flowing backward. It’s commonly used in sinks and dishwashers.

4. Double Check Valves

These are used in systems with moderate backflow risks, offering a second layer of protection.
