ASSE 5130 study guide
ASSE 5130 · Work through your exam, one topic at a time.
The ASSE 5130 credential - commonly described as the Backflow Prevention Assembly Tester certification exam - is a professional examination for individuals who test cross-connection control devices in potable water systems. It is intended for plumbing and utility tradespeople, water district and municipal field staff, irrigation and fire-protection contractors, and facilities maintenance technicians whose work requires demonstrating competence in verifying that backflow preventers are holding properly. The ASSE 5130 study guide has 6 sections and about 1,817 words.
01Cross-Connection Control Fundamentals and Regulations
A cross-connection is any actual or potential link between a potable water supply and a source of contamination or pollution. A backflow is the unwanted reversal of flow.
358 words, about 2 min02Backflow Prevention Assembly Types and Applications
Know the five core assemblies and their applications. The air gap provides the highest protection via physical separation and is not a mechanical assembly.
314 words, about 2 min03Testing Procedures and Equipment
Testers use a differential pressure gauge test kit with high- and low-pressure hoses and bypass valves to measure check valve opening pressures and relief valve opening points. Know the gauge's accuracy and calibration requirements; an out-of-calibration gauge invalidates results.
298 words, about 1 min04Troubleshooting, Repair, and Maintenance
Troubleshooting starts with the symptom. A continuously discharging RP relief valve usually indicates a fouled or failed first check, debris on the relief valve seat, or a failed relief valve diaphragm - not necessarily a bad relief valve.
297 words, about 1 min05Installation Requirements and Site Surveys
Correct installation determines whether an approved assembly actually protects. Key requirements: orientation per the manufacturer (horizontal or vertical), adequate clearance for testing and repair, proper elevation (PVB above the highest downstream outlet), drainage for RP relief discharge, and protection from freezing, flooding, and vandalism .
275 words, about 1 min06Recordkeeping, Reporting, and Safety
Accurate records protect public health and the tester. Maintain test reports with assembly make, model, size, serial number, location, test readings, pass/fail, tester name, certification number, and date.
