Pump
This is the main calculator. Set up your engine once, then run fast, consistent numbers on the fireground.
Walkthrough
Set up preconnects (required): add 1–3 lines so “Line 1/2/3” matches your engine.
Deploy a line: toggle Line 1–3 on, then use the + at the nozzle end to edit length/nozzle/elevation.
Pick a water supply: Hydrant % drop or Tender shuttle.
Tap Why? to see the pressure breakdown (NP + FL + elevation + appliance loss).
Tip: If your lines don’t match your engine, run Preconnect Setup again (you can change it anytime).
