Store description excerpt
BACKFLOW TESTER EXAM PREP: PASS YOUR CERTIFICATION. NEVER FAIL A TEST. The only mobile app with a full test procedure simulator for DC, RPZ, PVB, and SVB assemblies. Most candidates fail the practical because they know the theory but freeze on the exact test sequence. Wrong step order means a failed assembly test. This app fixes that. TEST PROCEDURE SIMULATOR Step-by-step walkthrough for every assembly type. Checkbox each sub-step, enter your PSID readings, get instant pass/fail feedback. Common mistakes highlighted at each step. Animated assembly diagrams show hose connections and test cock positions. Double Check Valve (DC): two-check testing sequence, minimum 1.0 PSID for each check, return to service procedure. Reduced Pressure Zone (RPZ): all five test steps in order, relief valve opening point test, Check 1 minimum 5.0 PSID, relief must open within 2.0 PSID below Check 1. Pressure Vacuum Breaker (PVB): check valve test, air inlet opening point, backsiphonage protection verification. Spill-Resistant Vacuum Breaker (SVB): complete sequence with pass/fail criteria. DIFFERENTIAL PRESSURE CALCULATOR Enter high-side and low-side gauge readings. Instant PSID with automatic pass/fail against all assembly minimums. DC checks need 1.0 PSID. RPZ Check 1 needs 5.0 PSID. Know instantly before moving to the next step. ASSEMBLY PARTS IDENTIFIER Tap any component on the interactive diagram: test cock locations 1 through 4, check valve positions, relief valve on RPZ, shutoff valve locations, hose connection points. Quiz mode tests parts identification — heavily tested on both written and practical sections. 350+ PRACTICE QUESTIONS TEST PROCEDURES: Step sequences, correct order of operations, what to do when a check fails, when to declare an assembly failed. ASSEMBLY COMPONENTS: Parts by name and function, test cock numbering, check and relief valve operation. CROSS-CONNECTION THEORY: Backpressure vs backsiphonage, hazard assessment (high vs low hazard), when to specify DC vs RPZ vs PVB vs air gap, cross-connection control program requirements. DIFFERENTIAL PRESSURE: PSID calculations from gauge readings, minimum requirements by assembly type, gauge operation and calibration. REPAIR AND TROUBLESHOOTING: Failed check identification, relief valve replacement, disc and seat inspection, when to condemn an assembly. REGULATIONS: ABPA, AWWA, USC FCCC standards, annual testing requirements, test report completion, permit requirements by jurisdiction. FREE: 5 questions per day, DC simulator demo (first 3 steps), PSID calculator. No account required. MONTHLY ($9.99/month): Full simulator for all 4 assemblies, unlimited questions, all tools, 3-day free trial. ANNUAL ($24.99/year): Save over 75 percent. Best value. LIFETIME ($39.99): One payment. Permanent access. PASS PROMISE: Complete all questions with 80% or higher average, hold active subscription for 3 months, still do not pass. We extend your access by 4 months at no charge. voltexam.com/pas
