Where should the hydraulic design information sign be located in systems with semiautomatic standpipes?

• A. Standpipe outlet
• B. Main drain valve
• C. Fire department connection
• D. Water supply control valve

Answer: (D)

Hydraulic design information signs carry the vital data about how a fire protection system is supposed to perform—flows, pressures, and the expected hydraulic behavior during operation. For semiautomatic standpipes, this information is most useful at the point where the system’s water supply is controlled and adjusted, because that’s where the operator or Fire Department responders will need to interpret and verify how the system is delivering water. Placing the sign at the water supply control valve puts the design data right where changes to the water supply are made and where the system’s hydraulic performance can be monitored during testing or a live incident. The standpipe outlet is where water exits, not where you determine or adjust the supply characteristics. The main drain valve is part of testing and drainage, not the primary control point for hydraulics. The fire department connection is for external water supply input from fire personnel, not for on-site hydraulic data reference.
