The specific signals an experienced plumber hiring panel grades on during the eight-second scan.

• License tier + state in the summary

  'Journeyman plumber, TX license #JP-87654' beats 'plumber.' License + state is the first scan.

• Hours by work type

  Commercial new-construction, residential service, repipe, drain-and-sewer. Breakdown signals real depth.

• Code edition (IPC or UPC)

  Most states adopt IPC 2018 or 2021; California + 18 other states use UPC. Name yours.

• Specialty endorsements (gas, backflow, medical gas, sprinkler)

  Specialty endorsements command premium rates. Surface them with the certifying body.

• Service-call resolution metrics

  First-trip resolution %, callback rate. The service-plumber KPIs.

• OSHA + lift / confined-space training

  OSHA 10/30, confined-space entry, scissor/boom-lift, fall protection. Construction-site table stakes.

1. 1

   Open with license tier + state + number

   Journeyman: 'Journeyman plumber, TX license #JP-87654 (2021); 9,200 commercial hours.' Master: 'Master plumber, CA C-36 #1124567 (2018); 16,000 hours; runs 6-person crew on multifamily new-construction.' Apprentice: '3rd-year apprentice, UA Local 130; 4,400 hours; passed cross-connection control short-course.'

   License tier + state is the first scan. Lead with it.

2. 2

   Break out hours by work type

   Commercial new-construction, tenant fit-out, residential rough-in, residential service, repipe, drain-and-sewer, gas-fitting. Total hours + breakdown tells a foreman which work you'll be productive on day one.

3. 3

   Name the code edition + AHJ work

   IPC 2018 / IPC 2021 / UPC 2021 / UPC 2024 — name your state's adopted code. Surface AHJ inspection counts + first-pass rates.

4. 4

   Surface specialty endorsements

   Gas-fitter, medical-gas (ASSE 6010 / 6020 / 6030), backflow (BPAT / BPAR), fire sprinkler (NICET), hydronics. Specialty work commands premium rates — surface it prominently with the certifying body.

5. 5

   Close with service-call KPIs or supervisory work

   Service plumbers: first-trip resolution + callback rate + call volume. Commercial journeymen+: apprentice mentorship, sub-foreman work. Master plumbers: contractor work, bid wins, supervisory metrics.

Each follows the [verb] [object] [number] structure hiring managers grade against. Copy them as a starting point, swap in your own numbers, and read the annotation to understand why each one works.

• Hours

  Logged 9,200 commercial hours through 2024 (4,200 new-construction, 3,400 tenant fit-out, 1,600 service); journeyman test passed first try in 2021 after the 4-year UA Local 24 apprenticeship.

  Why it works: Hours by work type, apprenticeship program named, first-attempt pass.

• Code

  IPC 2021-compliant across all work (Texas adopted via amendment); passed 22 city + county inspections in 2024 with first-pass approval on 21 of 22.

  Why it works: IPC edition, state context, inspection count, first-pass rate.

• Medical gas

  ASSE 6010 medical-gas installer + ASSE 6020 brazer; installed medical-gas systems on 3 ambulatory-surgery-center buildouts in 2024 (oxygen, vacuum, medical air); zero NFPA 99 cited deficiencies on AHJ inspection.

  Why it works: Two ASSE certifications, project count, system types, inspection outcome.

• Backflow

  Tested + repaired 320+ backflow assemblies in 2024 as a TCEQ-licensed BPAT; 100% report-submission compliance for the municipal cross-connection program.

  Why it works: Certifying body, role, volume, compliance outcome.

• Service

  Service-plumber on the residential dispatch rotation; first-trip resolution 78% across 480 calls in 2024 (avg 14/week); callback rate under 4%.

  Why it works: Service KPIs (FTR, callback rate, volume).

• New construction

  Roughed in DWV + water for a 38-unit ground-up apartment building (1.5″ + 2″ copper, 3″ + 4″ cast iron); passed all 6 rough + trim inspections first try.

  Why it works: Project scale, materials + sizes, inspection outcome.

• Gas

  Gas-fitter scope on a 14-unit restaurant build (CSST gas runs to 6 commercial appliances + 2 rooftop units); passed AHJ + utility inspection on first attempt.

  Why it works: Project type, equipment count, materials (CSST), inspection outcome.

• Hydronics

  Hydronics scope on a 22,000 sq-ft office building (radiant heat + chilled-water cooling, glycol fill); commissioned successfully with no leak callbacks through 12 months post-occupancy.

  Why it works: Project size, system type, commissioning outcome, longitudinal callback metric.

• Drain & Sewer

  Repaired the main 6″ sewer line on a 4-story commercial building after a CCTV inspection identified a 14-foot belly; trenchless pipe-burst replacement completed in 2 days with no business-day downtime.

  Why it works: Diagnosis method (CCTV), problem details, repair method (trenchless pipe burst), business outcome.

• Mentorship

  Mentored 2 apprentices through 2nd-to-3rd-year progression; both passed year-end school exams + first-attempt OSHA 30.

  Why it works: Apprentice progression, exam outcomes.

• Safety

  OSHA 30 (2024) + confined-space entry (2023) + scissor-lift operator (2024); 1,400 consecutive days without a recordable injury across the last 4 jobsites.

  Why it works: Three certifications with years, days-without-incident counter.

• Apprentice capstone

  Installed DWV + water + gas for an ADU as a 4th-year apprenticeship capstone; passed all inspections first try; homeowner occupied within 6 weeks.

  Why it works: For an apprentice candidate, a real shipped project with inspection outcome is high-leverage.

Patterns our writers see most often when reviewing plumber resumes — each one disqualifies candidates faster than weak experience does.

• Mistake

  Generic 'plumber' without license tier.

  Fix

  Lead with apprentice / journeyman / master + state + license number.

• Mistake

  Hours claim without breakdown.

  Fix

  Break hours by work type — commercial / residential / service / repipe.

• Mistake

  Generic 'code knowledge.'

  Fix

  Name IPC edition or UPC edition + state-adoption context.

• Mistake

  Listing specialty endorsements without certifying body.

  Fix

  Name ASSE / ABPA / NICET / state BPAT etc. The certifying body matters for verification.

• Mistake

  No safety certs.

  Fix

  OSHA 30 + confined-space + lift training are commercial-work table stakes.

• Mistake

  Service-call experience without KPIs.

  Fix

  Service work has measurable KPIs (FTR, callback rate, volume) — surface them.

• Mistake

  Two-page resume below master-plumber contractor level.

  Fix

  One page until plumbing contractor / master-license-track work justifies more.

• Mistake

  Listing every fixture brand you've installed.

  Fix

  Hiring foremen assume you can install standard fixtures. Focus on credentials + work types.

Strong verbs lead strong bullets. Replace generic openers (worked on, helped with, was responsible for) with the specific verb that matches what you actually did.
