United Association of Plumbers and Pipefitters

UA Apprenticeship Guide: How to Join the United Association in 2026

The United Association of Plumbers and Pipefitters is one of the oldest and most respected trade unions in North America. Founded in 1889, the UA represents workers across plumbing, pipefitting, HVAC, refrigeration, and sprinkler fitting in the United States and Canada. If you're considering a career in any of these trades, the UA apprenticeship is one of the strongest paths available.

What the UA Represents

The UA covers several distinct trades under one international union.

Plumbers install and service the water, gas, and waste systems in residential and commercial buildings. The largest membership category within the UA.

Pipefitters install and maintain industrial process piping - steam, chemical, and mechanical systems in factories, refineries, power plants, and large commercial facilities.

HVAC Technicians install and service heating, cooling, ventilation, and refrigeration systems. Represented by the UA in most union markets.

Refrigeration Mechanics specialize in commercial refrigeration systems - restaurants, grocery stores, and cold storage facilities.

Sprinkler Fitters install and maintain fire suppression systems in commercial and industrial buildings. Often a separate local within the UA.

Steamfitters work with high-pressure steam and hot water systems in large commercial and industrial facilities.

How UA Apprenticeships Work

UA apprenticeships are administered through Joint Apprenticeship and Training Committees operated jointly by the union and signatory contractors. Programs follow a national framework with some variation by local.

Duration is typically 5 years for plumbing and pipefitting apprenticeships. HVAC programs vary by local.

OJT Hours total approximately 10,000 hours for plumbing and pipefitting - slightly more than most other trades reflecting the complexity of the work.

Related Training Instruction covers pipefitting math, blueprint reading, welding, safety, and trade-specific technical content.

Pay Progression starts at approximately 40-50% of journeyman scale and increases every six months throughout the apprenticeship.

Benefits including healthcare are typically available from the start of the apprenticeship.
