How Cross-Connection Control Surveys Identify Hidden Risks

Clean, safe drinking water is something we often take for granted. However, hidden dangers can lurk within our plumbing systems. One significant threat is a cross-connection, a point where the potable (drinkable) water supply could potentially mix with non-potable water or other contaminants.

This contamination often happens through backflow (reversal of water flow due to pressure changes).So, how do you proactively protect your water supply? The answer lies in a comprehensive Cross-Connection Control Survey.

This survey isn't just a quick look around; it's a vital assessment designed to pinpoint potential hazards before they cause a serious contamination event. Here’s how a professional survey helps identify risks:

Systematic Plumbing Inventory

A certified surveyor meticulously examines your entire plumbing system. They identify and document every point where potable water connects to equipment or systems using non-potable water.

This includes common culprits like: Irrigation systems Boilers and chillers Fire suppression systems Hose bibs (especially those potentially submerged) Chemical dispensers (soap, cleaning solutions) Industrial process equipment

Identifying Unprotected Cross-Connections

The survey's primary goal is to find cross-connections that lack adequate backflow prevention assemblies or have the wrong type installed. Without the correct device, contaminants can easily flow back into the clean water supply during backpressure or backsiphonage events.

Assessing Existing Backflow Preventers

Even if backflow preventers are present, are they the correct type for the specific hazard level? Are they installed correctly according to code? Are they potentially damaged or malfunctioning?

The survey evaluates the suitability and condition of existing devices, identifying those needing repair, replacement, or initial installation.

Evaluating the Degree of Hazard

Not all cross-connections pose the same level of risk. A connection to a lawn sprinkler system (low hazard) requires different protection than a connection to a chemical tank (high hazard). The survey assesses the potential contaminant and classifies the risk level, ensuring the protective measures match the potential danger.

Detecting Unapproved Plumbing Modifications

Over time, plumbing systems can be altered. A survey helps identify any unapproved changes or additions that might have inadvertently created new cross-connection risks without proper safeguards.

Why It Matters

A cross-connection control survey provides a clear roadmap to water safety. By identifying these potential points of contamination, property owners and managers can:

• Implement corrective actions (installing or repairing backflow preventers).

• Ensure compliance with local water authority regulations and plumbing codes.

• Prevent costly contamination incidents and potential health crises.

• Gain peace of mind knowing their drinking water is protected.

Don't wait for discolored water or a boil water advisory. Investing in a professional cross-connection control survey is a proactive step towards safeguarding you
