Identity
Rely on professional or Town confirmation rather than pipe position alone.
Sheet 45 / Diagnostic set
Document the confirmed control before a crisis
Identify and label a confirmed control without forcing an unknown valve.
A main control is useful only when its identity, ownership, access, operating direction, and effect are understood. Do not force an unmarked, leaking, corroded, or resistant valve.
