ASSE 6020 study guide
ASSE 6020 · Work through your exam, one topic at a time.
ASSE 6020 is a professional-qualification exam in the ASSE/ASSP 6000 series, the family of personnel certifications administered by the American Society of Safety Professionals (ASSP), the organization formerly known as the American Society of Sanitary Engineering (ASSE). Our catalog publishes the blueprint as six weighted domains: cross-connection control program administration (15 percent), hydraulics and backflow principles (15 percent), backflow prevention assembly types and operation (20 percent), field testing procedures and test equipment (25 percent), troubleshooting, repair and maintenance (15 percent), and codes, standards and regulations (10 percent). The ASSE 6020 study guide has 6 sections and about 1,757 words.
01Cross-Connection Control Program Administration
A cross-connection control (CCC) program is a legal and operational document, not just a list of devices. A candidate must know the core elements: an enabling ordinance or authority, a written policy manual, a hazard classification scheme, a survey/inspection schedule, device tracking records, tester certification and test-report retention, enforcement procedures for noncompliance, and a public education component.
330 words, about 2 min02Hydraulics and Backflow Principles
Backflow is the reverse flow of water in a piping system, caused by backsiphonage (negative or reduced supply pressure) or backpressure (downstream pressure exceeding supply pressure). The governing relationship is pressure difference: flow goes from higher to lower pressure, so the exam question often hinges on identifying which side has the greater pressure.
308 words, about 2 min03Backflow Prevention Assembly Types and Operation
Know each device by its mechanical operation and its approved use. An air gap is the only non-mechanical protection and provides the highest degree of protection when properly sized and maintained.
306 words, about 2 min04Field Testing Procedures and Test Equipment
Field testing of an RPZ follows a defined order: (1) flush and inspect, (2) test the relief valve opening point, (3) test check valve 1 against backpressure, (4) test check valve 2. Record the differentials and compare to the assembly's published minimums.
288 words, about 1 min05Troubleshooting, Repair, and Maintenance
Troubleshooting starts with the symptom. Continuous relief discharge from an RPZ can mean a fouled first check, a failed relief valve seat, or debris.
251 words, about 1 min06Codes, Standards, and Regulations
Candidates must know how codes and standards interact. Model plumbing codes (such as the Uniform Plumbing Code and International Plumbing Code) set installation requirements, while consensus standards (such as those from ASSE, AWWA, and USC FCCCHR) define device performance and testing.
