Code Compliance, Survey Reports, and Local Program Requirements

Objective. The learner completes a cross-connection control survey form for a simulated building, identifies required assemblies by location, and explains the annual test and reporting obligations that the local water authority typically requires of the building owner and the licensed tester.

Why Cross-Connection Control Programs Exist

Every public water system is required to protect its distribution water from contamination at the point where it enters private property. Cross-connection control programs—run by local water authorities—carry out that protection by requiring building owners to survey their plumbing systems, install approved backflow prevention assemblies, and have those assemblies tested on a schedule. As a licensed tester, you are the professional who makes the program work in the field. Understanding the legal framework helps you fill out paperwork correctly, communicate with building owners clearly, and avoid liability.

The Legal Chain: Code, Program, and Owner Obligation

Federal and state safe drinking water rules require local water suppliers to maintain a cross-connection control program. Those suppliers then pass obligations downstream to their customers—the building owners—through service agreements and local ordinances. The International Plumbing Code (IPC) and the Uniform Plumbing Code (UPC) both contain chapters addressing cross-connection control, specifying where protection is required and what degree of protection applies. Local amendments may be stricter than the model codes; always check the authority having jurisdiction (AHJ) before you specify an assembly.

The building owner is responsible for:

Allowing the initial survey and any follow-up surveys requested by the water authority
Installing and maintaining approved assemblies at locations identified in the survey
Hiring a licensed tester to test each assembly at the required interval (commonly annually, though high-hazard sites or local programs may require more frequent testing)
Ensuring completed test reports reach the water authority by the deadline set in the program

The certified tester is responsible for:

Conducting the field test correctly using calibrated gauges
Completing the official test report form accurately
Submitting or transmitting the report to the water authority (in many programs the tester submits directly; in others the owner submits)
Notifying the water authority of any assembly that fails and cannot be repaired immediately, so the authority can take protective action on the service line

The Cross-Connection Control Survey Report

A cross-connection control survey is a systematic inspection of a building's plumbing to find every point where non-potable substances could enter the potable water system. The resulting survey report is a written record that documents each hazardous connection and the assembly required to protect it.

A typical survey form contains:

1. Property information – address, owner name and contact, water meter number, account number

2. Survey date and tester credentials – your name, license or certification number, and the certifying body (for example, ASSE International)

3. Hazard inventory table – one row per cross-connection listing: location in the building, connected equipment or system, degree of hazard (high or low), required assembly type, assembly manufacturer/model/serial number, and test interval

4. Installed assembly status – whether a compliant assembly is already present, needs replacement, or needs to be newly installed

5. Tester signature and date – you certify the accuracy of the report

6. Owner acknowledgment – the owner or authorized representative signs to confirm they received the findings

The water authority retains its copy to track compliance. The owner keeps a copy for their records. You keep a copy for yours.

Matching Hazard Degree to Assembly Type

The survey's most important technical judgment is matching each cross-connection to the correct assembly. The two main categories used in most programs are:

High-hazard connections (potential for health-endangering contamination): require a reduced-pressure principle backflow prevention assembly (RP) or an air gap. Examples in a commercial laundry include chemical injection lines for detergents and bleach, connections to boiler makeup water systems, and hose bibs where a hose could reach chemical reservoirs.
Low-hazard connections (potential for non-health-threatening contamination such as aesthetic or non-toxic substances): may be protected by a double check valve assembly (DC) where the AHJ accepts it. Examples include most fire sprinkler systems supplied with treated potable water and some irrigation connections without fertilizer injection.

Always verify with the AHJ. Some local programs classify all commercial laundry connections as high hazard because chemical concentrations are significant.

Annual Testing and Reporting Obligations

Most local programs require each assembly to be tested at initial installation, after any repair or replacement, and at least once every twelve months thereafter. The tester uses field test procedures published by the certifying body and records differential pressure readings at each check valve or relief valve port. Those readings must meet the manufacturer's minimum performance specifications and any code-required minimums.

When an assembly fails a field test, you must:

1. Document the failure on the test report

2. Notify the building owner immediately

3. Notify the water authority promptly—many programs require same-day or next-business-day notification for high-hazard failures

4. Re-test after the assembly is repaired or replaced and submit a passing report before the file is closed

Deadlines matter. Many water authorities set a fixed date by which all reports for a given facility must be on file. Missing the deadline can result in fines to the owner and, in serious cases, termination of water service.

Safety Reminders for Survey and Testing Work

Before entering mechanical rooms or accessing assemblies:

Wear required PPE: safety glasses, work boots, and gloves appropriate for the environment
Identify all energy sources on equipment adjacent to assemblies; follow lockout/tagout procedures before working on any pressurized system that must be isolated for testing
In commercial laundry environments, be aware of hot water, steam, and chemical exposure hazards
Confirm the space is adequately ventilated before entering enclosed mechanical areas

Accurate paperwork protects the public's health. A missed cross-connection on a survey form is not just a compliance failure—it is a potential contamination event.

Key terms9

Cross-connection control surveyA systematic inspection of a building's plumbing that identifies every point where a non-potable substance could enter the potable water supply, documented in a written report submitted to the water authority.

Authority having jurisdiction (AHJ)The organization, office, or individual—such as a local water authority or building department—that is legally responsible for enforcing code requirements in a given area.

Degree of hazardA classification of the severity of potential contamination at a cross-connection: high hazard indicates a substance that is health-endangering; low hazard indicates a substance that is non-toxic or aesthetically objectionable.

Reduced-pressure principle assembly (RP)A backflow prevention assembly containing two independent check valves and a pressure-differential relief valve, required at high-hazard cross-connections to prevent both backpressure and backsiphonage.

Double check valve assembly (DC)A backflow prevention assembly containing two independently operating check valves, acceptable for low-hazard connections in most programs but not approved for high-hazard applications.

Air gapA physical separation between the water supply outlet and the flood level rim of a receiving vessel; the only backflow protection method that is entirely mechanical and non-testable in the device sense.

Test reportThe official form completed by the certified tester documenting field test gauge readings, pass or fail status, and corrective actions taken; submitted to the water authority to demonstrate assembly compliance.

Test intervalThe maximum time allowed between successive field tests of a backflow prevention assembly, typically at least once every twelve months but more frequently if required by the local program or by the assembly's condition.

Local cross-connection control programThe specific rules, forms, deadlines, and enforcement procedures adopted by a water utility or municipality to implement state and federal safe drinking water requirements for backflow prevention.
