All tested sections (tank, supply and return pipes, remote fill, and various sump locations) passed the tightness tests with minimal reading changes and no visible drops. The service technician, Danny Lemos, used a 0-30 inHg vacuum gauge and 0-15 PSI pressure gauge, and holds an ICC license valid through 04/24/2025. The testing was performed in compliance with California Code of Regulations and followed industry standard procedures outlined in PEI/RP-1200.
