Water Mapping | Less Fatigue, More Knock | Residential Firefighting | Fully Involved (Ep. 10)

Water isn’t going where you think — and you’re getting smoked in the hallway. This episode shows how to map water on a second-floor push so you cool faster, protect the search, and save energy on short-staffed stretches.

Fireground problems this video tackles:
🚫 Water not reaching the fire room while you whip the nozzle around
🚫 Fatigue from constant nozzle movement on low-staffed pushes
🚫 Accidental fog/air entrainment while advancing a combo nozzle
🚫 Sloppy pre-staging on the stairs that kills your reflex time
🚫 “Shooting down” from above and missing the attic/voids

With Pete Morotto and Brian Hurst from Connecticut Fire Academy, you’ll learn how to:
✅ Bank the stream off the top doorframe to map water deep into the bedroom from the hallway
✅ Cool the common hallway with minimal movement, then advance with purpose
✅ Pick the right package: 1¾", 7/8" tip, ~160 gpm straight stream (and when dispersed patterns belong)
✅ Pre-stage hose smartly and keep the stairwell tenable for search
✅ Use high stream angles to reach ceiling/attic spaces; aim up under eaves to slow attic fire spread
✅ Flip to Vortex for hydraulic ventilation after the knock, then back to smooth bore — all at 50 psi

🧠 Use this video to train on:
– Residential second-floor fire attack with 1¾" and a 7/8" smooth bore (≈160 gpm)
– True “water mapping”: pattern, angle, and minimal-movement placement from the stairwell and hallway
– Coordinating nozzle cooling with search so you don’t soak the team or lose the hallway
– Pre-staging hose for the stairs and using position of advantage at door frames
– When to use hydraulic ventilation after knockdown to finish stronger
