Well Pump Installer study plan

Draw and label the full water path of a submersible system from well screen and drop pipe through pitless adapter, pressure tank, and service line, stating the function of each component.

Differentiate submersible, shallow-well jet, deep-well jet, and booster pump families by practical lift, depth, and flow limits, and match five scenario descriptions to the correct family.

List the purpose, normal setting, and common failure mode of the check valve, torque arrestor, safety rope, pressure switch, pressure tank, and relief valve.

Explain in your own words what a published pump curve shows, how efficiency peaks, and why a pump running far off its curve overheats or short-cycles.

Calculate total dynamic head for five given wells by summing static lift, drawdown, pressure head, and friction loss, converting freely between feet of head, psi, and meters.

Use a friction-loss table for galvanized, PVC, and polyethylene pipe to select a pipe size that keeps velocity under 5 feet per second for a stated flow.

Determine static water level, pumping water level, and drawdown from a described well test and explain how each changes the required pump setting depth.

Explain how a pressure tank stores usable water, and compute drawdown volume from tank size, precharge, and cut-in/cut-out settings.

Select a pump model for two case-study homes by plotting required flow and total dynamic head on candidate curves and choosing the model whose best-efficiency range covers the duty point.

Size the pressure tank, service line, and pressure switch settings for those same two homes, and justify each choice in two or three sentences.

Compare standard fixed-pressure, constant-pressure, and variable-frequency drive designs on cost, cycling, and water-hammer risk, and state when each is preferred.

Identify the electrical information on a pump and motor nameplate, including rated voltage, full-load amps, service factor, and phase, and explain what each figure means for circuit design.

Apply Ohm's law and the power equation to compute current, voltage drop, and wattage in single-phase and three-phase motor circuits.

Size branch-circuit conductors, overload protection, and disconnect means for three sample motors using nameplate full-load amps and the applicable derating factors.

Explain grounding, bonding, and ground-fault protection for a submersible pump installation, and describe what makes a well casing a shock hazard.

Interpret motor insulation resistance readings and describe how to take a megger reading correctly on a submersible motor.

Adjust a pressure switch cut-in, cut-out, and differential, and describe the symptom produced by each of four common misadjustments.

Trace the control circuit for a system using a control box, capacitor, and start relay, and explain the role of each device during start and run.

Describe start methods for three-phase and large single-phase motors, including magnetic starters, overloads, and the reason for reduced-voltage starting.

Set up and interpret a variable-frequency drive's basic parameters (pressure setpoint, minimum frequency, sleep mode) and list two failure modes caused by wrong settings.

Sequence a full installation from site verification and well inspection through pump assembly, setting depth, pitless connection, tank placement, and wiring.

Assemble a pump end correctly, including torque arrestor, cable guard, splice sealing, and safety rope, and list three assembly errors that cause callbacks.

Write and walk through a startup checklist covering electrical checks, air purging, gradual valve opening, pressure verification, and disinfection with the correct chlorine dose and contact time.

Perform a yield test and drawdown measurement, then record results on a commissioning form a customer could sign.

Diagnose eight written fault scenarios (no water, low pressure, short cycling, tripped breaker, noisy pump, dirty water) by naming the likely cause and the confirming test for each.

Demonstrate the sequence for electrical troubleshooting: de-energize, lock out, verify absence of voltage, measure winding resistance, megger insulation, and check the capacitor and switch.

Apply job-site safety rules for confined spaces, trenching, rigging, hoisting, and electrical lockout, and identify the required personal protective equipment for each task.

Summarize the regulatory duties that apply to a well installation, including wellhead protection and setback, backflow prevention, disinfection, and reporting to the local authority.

Complete two full-length timed practice exams under test conditions and score each domain separately to expose remaining weak areas.

Re-teach the two lowest-scoring domains by rewriting the missed concepts in your own words and building a short reference sheet for each.

Rehearse a full customer-facing service call script, from intake questions through diagnosis, repair recommendation, and safe return to service.

Verify final recall of safety, electrical, and sizing formulas by completing a 40-item rapid-fire review with no reference material.
