How are Wisconsin Plumber salaries calculated on this page?

Nominal wages come from BLS Occupational Employment and Wage Statistics (OES) — annual employer surveys, May 2026 reference period. Real-wage figures use BEA Regional Price Parities (2023 vintage) to adjust for state-level cost of living. No self-report or jobs-board data is mixed in.

Why is the BEA RPP for Wisconsin different from a single CPI number?

BEA splits regional price parity into three components — goods, services, and rents — reweighted to the BEA's national consumption basket. Wisconsin's overall index of 93.2 reflects rents 78.3, services 89.5, and goods 94.3.

How wide is the wage spread in Wisconsin?

P10 to P90 spans $48,960 to $114,460. That spread captures entry-level to top-quartile pay, including specialty differentials and metro-area variance within the state.

When does this data update?

BLS OES releases a new May reference set roughly each spring; we re-run the ETL pipeline within two weeks of release. BEA RPP refreshes annually. The last-synced timestamp at the top of this page reflects the most recent build.

Union vs non-union plumber pay in Wisconsin?

BLS does not split union from non-union compensation. In Wisconsin, UA (United Association)-represented plumbers and pipefitters typically earn 20-40% above non-union median once health, pension, and annuity contributions are included. The premium is concentrated in industrial, commercial, and government project work; residential service plumbing in Wisconsin is predominantly non-union. UA Local hall job boards in Wisconsin are the cleanest reference for current scale and benefit values.

Service plumber vs new construction plumber in Wisconsin — pay difference?

BLS aggregates plumbers, pipefitters, and steamfitters (47-2152) into one category. In Wisconsin, residential service plumbers (drain cleaning, water heater replacement, repair calls) earn near or below BLS median; commission-based service models in Wisconsin can produce above-median earnings for high-volume techs but with substantial variance. New-construction plumbing in Wisconsin pays above median for pipefitter and steamfitter specialties on industrial and commercial projects, especially when union-rate prevailing-wage rules apply on government work.

How long is the Wisconsin plumbing apprenticeship and what's the master plumber payback?

Wisconsin typically requires 4-5 years (8,000-10,000 hours) of supervised on-the-job training plus 144+ classroom hours per year before the journeyman plumber exam. Master plumber licensure in Wisconsin requires an additional 2-5 years post-journeyman plus a separate exam, and unlocks business ownership, permit-pulling authority, and significantly higher compensation — owner-operator master plumbers in Wisconsin routinely earn 1.5-3× the BLS journeyman median once business profit is included. Apprenticeship pay starts at 40-60% of journeyman scale and ratchets up annually.
