Union vs Non-Union Plumber Pay:
25-40% Total Compensation Difference
Updated 17 April 2026
The base wage gap is real, but the total compensation gap is where union membership truly separates itself. Here is the full picture.
Published union wage, 4 Locals
$62.00 - $94.00/hr
Their total package
$103.28 - $149.76/hr
All plumbers, US median
$30.67/hr
All plumbers, US 90th pct
$52.13/hr
Union figures are the four Locals with a published 2026 scale, listed with their sources below. National figures are BLS OEWS May 2025, SOC 47-2152, covering union and non-union alike. The four Locals sit in high-cost metros, so the gap between the two is not a pure union premium.

What "The Package" Actually Means
A plumber who compares a union base wage against a non-union hourly offer and reads the difference as the whole story is reading only the first line of the wage sheet. The employer contributions below it are itemised, and they are large. Here is Chicago Local 130's, line for line, off its published appendix C.
UA Local 130 Chicago journeyman, 1 June 2026 to 31 May 2027
Source: Plumbers Local 130 UA, PCA wage rate sheet, appendix C. The same sheet also lists dues check-off, target, building and PAC lines totalling $4.12 an hour, but those are payroll deductions from the member rather than employer contributions, so they are not part of the package. Chicago is the lowest of the four published scales on this page; San Francisco Local 38 adds $55.76 an hour to a $94.00 wage.
