Well Pump Service Reports: Pressure, Flow and Handoff

Consider an illustrative no-water call at a rural restaurant. The owner hears clicking near the tank, and a technician restores flow after replacing a control. “Working now” would leave the next crew without the original readings, test conditions or water-use status.

A plumbing service report should connect the symptom, evidence, authorized repair and tested result. Restored pressure and drinking-water clearance are separate outcomes.

Identify the customer, well and system category

Record the customer's words, symptom timing, affected outlets and preceding events: outage, repair, flood, freeze, demand change or repeated trip. Identify who can approve diagnosis, further testing, parts and emergency charges. Carry that authority onto the plumbing work order, as explained in the general service work-order workflow.

Private ownership does not establish regulatory status. EPA's public-water-system definition includes systems supplying human consumption through pipes or constructed conveyances to at least 15 service connections, or an average of at least 25 people for at least 60 days annually. Privately owned systems can qualify.

Record connections, people served, operating days, uses, system ID and responsible operator. If the classification is uncertain, consult the applicable drinking-water program before bypassing treatment or representing return-to-service status. Check jurisdiction-specific contractor credentials and reporting duties as well.

Map the equipment before diagnosing it

Identify the well location and record number, pump, controller, pressure tank, gauges, treatment equipment, distribution branches and alternate power sources. Preserve models, serials, ratings, settings and prior repair history.

Label old completion-log data by date. A historic water level or pumping rate is not today's measurement. Photograph labels and the flow path, including treatment and bypass positions.

A useful report separates five possible problem areas: power/control, pressure storage, plumbing restrictions or leaks, pump/well performance, and sanitary condition. Oregon's dry-well guidance illustrates why no water does not necessarily mean a permanently dry well: pump placement, structure and maintenance may require assessment.

Establish the safety boundary

Identify electrical sources, stored pressure, lifting needs, wet equipment, pits or vaults and other task hazards in the job hazard analysis. Record the qualified person, governing work procedure, isolation points, verification and deferred work.

For covered general-industry work, OSHA §1910.333 generally requires exposed live parts to be de-energized unless a specified exception applies. Section 1910.334 limits electrical testing to qualified persons and addresses suitable test equipment. Identify the rules governing the actual work classification and any State Plan requirements; a report form does not authorize energized testing.

Do not treat a pressure switch as proof of electrical isolation. Record pressure relief before opening a pressurized component, using the applicable procedure.

Make readings repeatable

For each material reading, include instrument ID, units, point, time, system state and comparison source. The inspection report should distinguish observed readings from setpoints and assumptions.

NGWA's professional checkup guidance includes output, water levels where possible, motor performance, pressure equipment and sanitary condition. It is an inspection framework, not a universal diagnostic recipe.

A short faucet flow check does not prove sustainable well yield. Tank drawdown means water delivered between cycle pressures; water-level drawdown means a change in well level. Keep those meanings separate.

For an equipment-specific example, Pentair's Pro-Source manual calls for checking precharge without water in the tank and distinguishes control arrangements. Use the installed model's instructions rather than a universal pressure setting or the tank's nominal shell volume.

Record the approved action and its limits

State the diagnosis and supporting test, or label it inconclusive. Obtain approval before pump pulling, excavation, electrical alteration or replacement exceeds the original scope. Use a change order for the revised work and price.

List exact installed parts, compatibility basis, final settings and removed-part disposition. If treatment was bypassed, record authority, implications and the position left behind; connect treatment work to the filtration proposal.

Retest under a defined demand, with pressure, flow, duration, cycling, accessible leaks and control status recorded. Identify untested branches and temporary measures.

Give water-quality status its own handoff

CDC recommends private-well testing at least annually for total coliforms, nitrates, total dissolved solids and pH, and after repair or replacement of any well-system part. Use a state-certified laboratory and local advice for additional analytes.

Record applicable disinfection, sampling, interim-water instructions and clearance responsibility. Distinguish “mechanically restored,” “sample pending” and an actual laboratory result. Deliver those limits and follow-up dates with the completion sign-off.
