Drafting the Hydrant Valve

Drafting the Hydrant Valve is an industrial heritage catalog and hydraulic head-loss simulator designed for municipal engineering preservationists, historic fire-apparatus collectors, and waterworks historians. This application provides a structural ledger for cataloging mid-19th-century cast-iron municipal hydrant barrels, leather flap-gate foot valves, square operating-nut drive ratios, and frost-case sleeve tolerances, capturing early municipal water supply mechanics before modern standardized fittings.
