Plumbing code outlines the best and most modern methods to be used in plumbing installations. Since the plumbing in any private or public building is a part of the community water and sewage disposal system, it is vital that such installations should not be left to the discretion of irresponsible individuals. The protection of the public health and safety must be maintained by the establishment of sound code provisions.

A plumbing or sanitation code is not a “plumber’s code”, like a code of honor. It is rather a set of Rules and Regulations imposed by cities, counties, and states on anyone who undertakes any work involving the installation of drinking water, sewer or toilet facilities in homes, offices, factories, schools and hospitals. Regardless of who might do the work, plumbing and sanitation codes require that it be done in a specific, safe manner because it was found that failure to do so caused widespread disease, which can be crippling and deadly-to the community.

Plumbers and most jurisdictions within the United States typically follow the Universal Plumbing Code (UPC) set forth by the International Association of Plumbing and Mechanical Officials (IAPMO), which is updated every couple of years to take into account new technologies and knowledge. While the UPC is the general standard for plumbing codes, be aware that your city, county, or state may have different or additional plumbing codes that must be followed. It is best to always contact your local authorities before beginning any DIY plumbing project, and be sure to work with a licensed plumbing contractor for bigger or more involved projects to ensure not only that you’re following the law, but also that your project will be completed in the safest, most effective manner.

      Hi Brett – you’ll have to consult your local authority to see what code is in use in your area, but that doesn’t sound normal at all! You might also get some good information if you post your question over at http://www.plbg.com
