2015 Seattle Plumbing Code

Based on the ANSI accredited American National Standard 2015 Uniform Plumbing Code, the Seattle Plumbing Code has been integrated into a convenient, single publication that includes updates and errata pages.

The codes of practice attempt to minimize public risk by specifying technical standards of design, materials, workmanship and maintenance for plumbing systems. The main aims of the code are:

To ensure that planners, administrators and plumbers develop the required competency to ensure that the codes are applied and upheld;
That standards are set to ensure that plumbing assemblies, materials and technologies are safe and effective;
To ensure that plumbing installations meet these standards;
To ensure safety and effectiveness continuously through the proper maintenance of these installations.
