Common Backflow Risks That Require Professional Attention

Cross-Connections

Improperly connected plumbing systems can allow contaminated water to enter clean water lines, creating serious health risks.

Poor Maintenance

Skipping annual testing or neglecting minor repairs can cause backflow devices to fail when needed most.

High Water Pressure

Fluctuations in pressure can overwhelm backflow devices, allowing dirty water to reverse flow into drinking water systems.

Damaged Backflow Devices

Worn or broken RPZ/DCV units lose effectiveness, requiring immediate servicing or replacement to ensure compliance and safety.

Commercial Equipment Risks

Restaurants, irrigation systems, and industrial sites often require specialized backflow devices to prevent contamination from chemicals or waste.
