Plumbing and hydronic wholesale valve and connection data for AI
Two valves can look alike while using different connections and documented applications.

Two valves can look alike while using different connections and documented applications. EPA WaterSense publishes plumbing product specifications in covered categories. A wholesaler can create a catalog and visual matching exercise with an unpowered display. EPA WaterSense product specifications
Lay out two inert valve shapes and photograph the end profiles. Give one a matching product card and the other a card with the connection field missing. Ask what each photo and record can establish. Keep physical appearance separate from the claim that a product fits the fictional order.
Use original diagrams and no live plumbing, pressure, heat or client records. Keep engineering and installation decisions with qualified staff.

Original Fiund exercise
Similar end profiles do not supply a missing documented connection field
Two original inert valve shapes and a dummy order use abstract connections. There is no real plumbing, pressure, heat, engineering specification or installation instruction.
| Record | Source | What it records |
|---|---|---|
| HVW1 | Practice order | Requires model family V, connection C1 and documented application A1. All three fields stated. |
| HVW2 | Prop A | Matching product card V-A/C1/A1 and readable A label. Photo shows end profile consistent with the fixture drawing. |
| HVW3 | Prop B | Similar end profile, card names V-B and A1 but connection field blank. No calibrated geometry or reviewed C1 association. |
Question for the model
Which prop has full documentary support, and can B's visual profile substitute for the missing connection specification?
Show the reference answer and checks
HVW1 and HVW2 match A across the required family, C1 connection and A1 application in this exercise. HVW3 supports B's identity and A1 field, but its similar profile does not establish C1 without a matching specification or reviewed measurement. Flag the partial match instead of relying on shape or treating one documented application as proof of all fit conditions. No actual plumbing selection or installation is recommended.
- Inferring a connection type from an uncalibrated lookalike profile.
- Treating a matching application field as full fitment when another required attribute is absent.
Fields to preserve
- Valve model and required application
- Defines the target.
- Connection and supporting card
- Supports exact match.
- Visual profile and missing measure
- Limits inference.
Test another case
Add B's card confirming C2 rather than C1. Require a documented mismatch instead of accepting the visual resemblance.
Use original inert props and drawings. Exclude actual client and operating data; qualified staff retain engineering decisions.

Describe the sources you control, the task they could support and what has already been checked. Use the existing-data assessment for an archive or the collection brief for a new recording project. The contributor agreement defines Fiund’s licensing authority and compensation. A guide or fictional exercise does not establish an accepted collection or a sale.
