Find Licensed Plumbers Across the United States

The United States spans multiple climate zones, each presenting unique plumbing challenges. Northern states experience freezing temperatures requiring extensive freeze protection for exterior pipes, hose bibs, and water service lines. Plumbers in these regions specialize in insulation techniques, heat tape installation, and proper pipe depth to prevent costly freeze damage.

Southern and coastal states face hurricane risks and high humidity. Plumbers in these areas focus on backflow prevention, sump pump systems, and moisture-resistant materials to prevent mold growth. Gulf Coast and Atlantic states require robust drainage systems to handle heavy rainfall and storm surge flooding.

Western states dealing with drought conditions emphasize water conservation. Plumbers install rainwater harvesting systems, greywater recycling, drip irrigation, and EPA WaterSense fixtures to maximize efficiency. Hard water is common across the Midwest and Southwest, making water softener installation and maintenance a primary service. Licensed plumbers understand regional codes and climate-specific best practices for your area.

While plumbing licensing occurs at the state level, most states adopt one of two primary model codes as their foundation. The International Plumbing Code (IPC), published by the International Code Council (ICC), is adopted in 37 states, the District of Columbia, Guam, and Puerto Rico. The IPC sets minimum regulations for plumbing systems to protect public health and safety.

The Uniform Plumbing Code (UPC), published by the International Association of Plumbing and Mechanical Officials (IAPMO), is the only US plumbing code designated as an American National Standard by ANSI. Western states including California, Oregon, and Nevada typically base their state codes on the UPC. Both codes are updated on three-year cycles to incorporate new technologies and materials.

Individual states and municipalities may amend these model codes to address local conditions. Some states like New Jersey use alternative codes such as the National Standard Plumbing Code (NSPC). Regardless of which code your jurisdiction follows, licensed plumbers must stay current with local amendments and continuing education requirements to maintain their credentials and ensure code-compliant installations.
