Safety — source reliability

The AI is the interface. The archive is the source.

H0U53 is loaded into a third-party AI tool. The AI can repackage, summarize, and route — but it cannot be the source of truth for home-repair facts. Here’s the order of sources H0U53 expects the AI to defer to.

  1. Tier I

    Manufacturer instructions for your specific model

    The single most authoritative source for installation, torque, voltage, pressure, capacity, warranty, and recall details. Always specific to the exact SKU. Found in the printed manual or the manufacturer’s website (search by model number, not product name).

  2. Tier II

    Your local authority having jurisdiction (AHJ)

    City or county building department, plus utilities and HOAs. They tell you what edition of the code is adopted, what permits and inspections apply, and what local amendments exist. They override generic code references.

  3. Tier III

    Model codes — NEC, IRC, IPC, IFGC, IMC, etc.

    Authoritative when current, but each jurisdiction adopts its own edition with its own amendments. Treat a code reference as a starting point; verify the adopted edition with your AHJ.

  4. Tier IV

    Industry / trade organizations

    ICC, ASHRAE, NFPA, IAPMO, EEI, AHRI — they publish standards, technical bulletins, and trade education. Reliable but specialized.

  5. Tier V

    Licensed-trade explainers

    Plumbing-supply websites, electrical-distributor blogs, manufacturer’s knowledge bases. Generally accurate, but trade context varies and they’re sometimes selling something.

  6. Tier VI

    Generic web how-tos

    Use cautiously. Often outdated, often missing local-code context, often skipping safety steps for brevity or content-farm reasons. Verify against tiers I-IV before acting.

  7. Tier VII

    Forum posts, social media, and uncited advice

    Useful for “am I crazy or is this normal” pattern matching. Never authoritative.

What this means in practice

When the AI gives you a specific number — torque, voltage, pressure, capacity, fitting size — and there’s no Tier I or II citation in the response, treat it as a starting point that needs verification. The AI is fluent. Fluency isn’t the same as accuracy.

H0U53’s routes are designed to make the AI label uncertainty out loud — “possible,” “likely,” “verify with the manufacturer,” “ask your local authority.” If you see definitive claims without that hedging, push the AI to cite a Tier I or II source.
