In forward lay in water supply operations, which describes the placement of the supply hose?

• A. Laying supply hose from the engine toward the hydrant to bring water to the pump.
• B. Laying supply hose from the hydrant toward the engine to bring water to the pump.
• C. Running a booster line from the hydrant to the nozzle without the engine involvement.
• D. Using a Siamese connection to feed multiple lines from one source.

Answer: (B)

Forward lay means placing the supply hose from the hydrant toward the engine so the water can be pumped into the engine’s pump. That’s why describing the hose as being laid from the hydrant toward the engine to bring water to the pump is the best fit. If you lay the hose from the engine toward the hydrant, you’re describing a different setup where the engine is between the water source and the pump. The option about running a booster line directly from the hydrant to the nozzle bypasses the engine’s pump, which isn’t how a typical supply line is established. The Siamese connection idea relates to splitting or combining flows to multiple lines, not the direction of the supply hose toward the engine.
