Comparison index
Faucet part identification matrices
Use a matrix when no single model number settles the answer. Each comparison isolates a bounded set of attributes—such as handle count, control function, dimensions, broach, thread, ports, or connector geometry—and shows what evidence should send you to a record.
Use the index deliberately
Choose the record that matches the evidence you have
- Pick the matrix for the fixture and part class before comparing physical features.
- Measure with one method and one unit system; conversions and camera perspective can hide small differences.
- Treat pressure-balance, thermostatic mixing, and diverter functions as different jobs even when parts look related.
- Use the result as a route to a source-linked record, not as permission to force an uncertain part into the valve.
