Why Does It Always Have to be Done That Way?

Paul Shapiro

Myth #10

Myth 10: The nozzle pressure for a smooth bore tip on a master stream is 80 psi. Pressures higher than this will create a broken stream.

Reality: Again, I feel that the opposite is true. Nozzle pressures higher than 80 psi can create a harder hitting, farther reaching stream that is capable of penetrating deep into the seat of the fire problem. Nozzle pressures pushing 175 have been successfully used in master stream operations. The rule to remember is to not exceed the maximum allowed inlet pressure for the appliance being used.

This master stream is delivering 614 GPM through a 1-1/4” tip at 175# NP
