A standard diagram shows the valve body, inlet and outlet connections, nuts, gaskets, and shut-off stems. Identifying these parts ensures accurate diagnosis and replacement when worn or damaged, saving time and preventing water damage.

The core components include a valve seat, stem, washer, and nut. The stem turns to open or close flow, while the washer seals against the seat to stop leaks.
