At the heart of our production line for flue-type gas water heaters lies a critical checkpoint — the final safety and integrity test. This step embodies our unwavering commitment to quality and customer safety.

Each unit is carefully mounted onto our dedicated testing station, where it undergoes a rigorous examination for any potential gas or water leaks. Our technicians conduct a comprehensive dual-pressure test, meticulously checking all connections, valves, and seals under simulated operational conditions. This precise procedure ensures that every heater meets the strictest safety standards before it leaves our facility.

Only after passing this stringent inspection does the unit receive the official QC Pass stamp — a mark of trust, symbolizing that the product is certified safe, reliable, and ready for its lifelong role in your home.

This final seal is more than just an ink mark; it is our promise. A promise of security, durability, and the professional diligence we apply to every single product we make. Because your safety is not just a step in our process — it is our foundation.
