Tank to Pump

Checkoff Prep

Checkoff Prep is a structured study path for firefighters getting ready for a driver/operator checkoff (skills test). It pulls the right lessons, drills, and calculators together into one curriculum so you can show up prepared.

This is a preparation aid — it does not certify you and is not a checkoff record. It does not replace hands-on pump training, instructor evaluation, or your AHJ's requirements. Use it to walk in ready.

Checkoff Prep tracking is part of Pro (see Account & Progress).

The curriculum

The path is organized into four sections that build from the mental model up to whole-incident decisions:

  1. Know the pump — trace how water moves from intake to discharge, name every gauge and control, and get water on a line from your own tank.
  2. Water supply & pressure — read static and residual pressure to judge a hydrant, keep the pump cool while holding water, manage recirculation and heat, plan so your tank doesn't run dry, and hold a line on a weak hydrant.
  3. Pump hydraulics math — friction loss, building a pump discharge pressure, reading the pump curve and capacity tag, automatic nozzles, attack-line and high-flow pressures, uphill corrections, and pumping through a wye.
  4. Put it together — avoid the common pump-operator myths, flow the first line start to finish, transition from tank to hydrant, balance two working lines, and recalculate when the stretch changes.

Each item links you to the lesson, drill, or calculator that teaches it, and your progress through the curriculum is tracked.

Hands-on skills checklist

The app also gives you a printable checklist of hands-on skills to complete with an evaluator on real apparatus — for example: priming from a draft source, completing a tank-to-pump transition with water on a line, establishing and transitioning to a hydrant supply, setting and checking the relief valve or pressure governor, flowing two attack lines at once, and recognizing and recovering a loss of prime or a cavitating pump.

These hands-on items are not graded or tracked in the app — they're a prompt for what to practice and demonstrate in person with your instructor.

Checkoff Prep helps you prepare; it does not certify competence or replace hands-on training and instructor evaluation. See Safety & Disclaimer.
