ASSE 6040 study guide
ASSE 6040 · Work through your exam, one topic at a time.
ASSE 6040 - the Cross-Connection Control Program Specialist credential - is a professional qualification aimed at the people who run drinking-water protection programs rather than at the tester who simply hangs a gauge on a valve. Typical candidates administer backflow prevention programs for municipal water utilities, campuses, hospitals, military installations, and large industrial sites: they decide which premises need isolation, review site hazard surveys, approve assembly selections, track annual testing, manage tester qualifications, and answer to regulators after a contamination incident. The ASSE 6040 study guide has 8 sections and about 2,294 words.
01Cross-Connection Control Concepts and Terminology
A cross-connection is any actual or potential physical connection between a potable water supply and a source of contamination or pollution. It becomes a backflow event only when a pressure differential drives water the wrong way.
335 words, about 2 min02Public Health Significance of Cross-Connections
Cross-connection control exists to prevent waterborne illness and contamination of the public distribution system. Candidates should understand the transmission pathways : a cross-connection can introduce pathogens (bacteria, viruses, protozoa), chemicals (solvents, pesticides, boiler treatment), and radiological or industrial contaminants.
304 words, about 2 min03Backflow Prevention Assemblies and Devices
Candidates must know the mechanical and non-mechanical options and their applications: Air gap : physical separation; highest protection; requires no testing but needs inspection. RPZ (reduced pressure principle assembly) : two check valves plus a differential relief valve; high hazard; backpressure and backsiphonage; must discharge from relief valve under failure.
323 words, about 2 min04Codes, Standards, and Regulations
Cross-connection control is governed by a layered system: federal safe drinking water laws set the baseline; state primacy agencies adopt rules; local ordinances and plumbing codes implement them. Candidates should recognize the roles of health departments , water utilities , and building officials , and understand that the authority having jurisdiction (AHJ) determines specific requirements.
297 words, about 1 min05Program Development and Administration
A cross-connection control program needs legal authority , administrative structure , hazard assessment , device requirements , tester certification , inspection and testing , recordkeeping , enforcement , and public education . Candidates should understand the program cycle : inventory, classify, require protection, verify installation, test, track, and re-evaluate.
255 words, about 1 min06Premises Isolation and Hazard Assessment
Premises isolation (containment) protects the public main at the service connection. Internal protection protects fixtures and points of use inside the building.
249 words, about 1 min07Field Testing, Inspection, and Maintenance
Field testing verifies mechanical operation (check valve tightness, relief valve opening, air inlet function). Inspection verifies condition, installation, orientation, clearance, drainage, and tagging.
263 words, about 1 min08Records, Reporting, and Program Evaluation
A defensible program keeps inventory records , hazard classifications , device records (make, model, serial, location), test and repair reports , tester certifications , notices , and enforcement actions . Records must be accurate, complete, retrievable, and retained per policy.
