Series Part 5 of 8: Houston 3003.4 vs. ASME A17.1 – Pit Flood Detection

The water’s gone—now it’s time to reset the elevator. But how exactly should that happen?

🛠️ Houston 3003.4:

“Return to normal automatic operation… shall require a manual reset, accessible only by a Texas licensed elevator contractor.”

🗝️ ASME A17.1:

“to remain activated until the flood detection means is manually reset by elevator personnel. The reset means shall be Group 1 Security”

🔍 Summary:
✅ Both codes agree:

  1. Reset must be manual
  2. Reset must be done by qualified elevator personnel

They differ on how that reset is performed:

  • A17.1 requires a Group 1 key
  • Houston allows flexibility—keys, buttons, keypad reset, etc.—as long as access is restricted to licensed contractors

📊 Coming next: Which elevators are affected by these rules? Let’s look at the floodplain zones. 🌐

  • A100-PFD Pit Flood Protector

    When water is detected in the pit, the pit flood protector moves the elevator and its passengers to pre-determined safe floor.

  • A100-PFS Pit Flood Switch

    A robust, waterproof float switch for detecting water or other liquid intrusion into the elevator pit.
