Backflow Tester Exam Prep vs Journeyman Plumber Exam 2027

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 c**k 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 c**k 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 c**k 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.
