Clack V3003 is the WS1 meter assembly; V3118-01 is the turbine subassembly listed inside it. Ordering the turbine alone does not imply the meter housing, nut, plug, mixing valve, or every seal is included.
Assembly boundary
| Number | Manual description | Confirmed relationship |
|---|---|---|
| V3003 | WS1 Meter ASY | The manual note says V3003 includes V3118-01 turbine assembly and V3105 O-ring 215. |
| V3118-01 | WS1 Turbine ASY | Turbine subassembly; do not imply the complete V3003 meter package. |
| V3003-01 | WS1 Meter Plug ASY | Separate non-meter plug configuration. |
Selection checklist
- Confirm the body is WS1 and the existing connection is the metered configuration.
- Inspect the housing, turbine, cable/drive interface, and O-ring separately.
- Retain the complete V-series number and package evidence.
- Do not infer WS1.25 or other body fitment from controller appearance.

Service safety and limits
These checks identify a valve and narrow a parts search; they are not a substitute for the manufacturer service procedure. Before opening a valve, use the documented bypass procedure, isolate water, relieve pressure, and disconnect power. Water-treatment valve service should be performed by a qualified person. Stop if the label, flow direction, wiring, or part suffix does not match the cited manual.
