1. Health and Safety Standards

Plumbing codes include provisions for maintaining sanitary conditions and preventing contamination of drinking water. Proper installation and maintenance of plumbing fixtures and systems reduce the risk of waterborne diseases and ensure safe water supply for residents.

Codes establish minimum standards for materials, construction techniques, and installation methods. Compliance with these standards ensures that plumbing work meets quality benchmarks, promoting durability and reliability of plumbing systems over time.

3. Environmental Protection

Many plumbing codes now incorporate provisions for water conservation and environmental sustainability. Requirements for efficient fixtures, water reuse systems, and proper disposal of wastewater contribute to reducing water consumption and environmental impact.

Plumbing Code Requirements in Green Bay, WI

In Green Bay, WI, plumbing code requirements cover various aspects of plumbing installations and renovations. Some common requirements include:

1. Permitting and Inspection

Most plumbing work in Green Bay requires a permit issued by the Department of Public Works or another relevant authority. Permits ensure that proposed plumbing projects meet code requirements before work begins. Inspections during and after construction or renovation verify compliance with approved plans and code standards.

2. Fixture Requirements

Plumbing codes specify the types and installation standards for plumbing fixtures such as sinks, toilets, showers, and water heaters. Requirements may include minimum flow rates, accessibility standards, and installation clearances to ensure proper function and safety.

Requirements may specify acceptable materials for pipes, fittings, and joints based on durability, corrosion resistance, and compatibility with local water conditions.

4. Backflow Prevention

To protect against the contamination of potable water supplies, plumbing codes require the installation of backflow prevention devices where necessary. These devices prevent the reverse flow of non-potable water or substances into the drinking water supply, safeguarding public health.
