Pipe corrosion can lead to costly repairs and system failures. Discover the main causes of corrosion, signs to watch for, and practical prevention methods to maintain your plumbing’s integrity.

Licensed plumbers must understand the regulatory requirements to install appropriate backflow devices for each situation, perform ongoing testing and maintenance, and repair or replace faulty equipment. Their expertise is critical for properly functioning devices.

A non-testable dual check valve is sufficient for backflow prevention device installation in low-hazard environments with minimal risk of dangerous contamination. Simple single-story homes and standalone commercial buildings often fall under the low-hazard category.

Any recycled or reclaimed water system for non-potable reuse must have a reduced pressure zone device or registered air gap installed to separate it from drinking water supply lines. This prevents any accidental cross-contamination.

Critical protection is required for high-hazard situations involving severely toxic and dangerous contamination risks. A reduced pressure zone device must be installed for these scenarios to prevent backflow.

Backflow occurs when water flows in the opposite direction from its intended supply line and course, allowing contaminants to enter the drinking water system. This reversal in flow direction can be caused by back pressure or back-siphonage. Backflow contamination can lead to widespread outbreaks of illness from bacteria, chemicals, or other hazardous substances.

Potentially hazardous situations require a testable backflow prevention device like a double-check valve to be installed. This includes hospitals, multi-story buildings, food processing plants, and complex plumbing systems.
