Designated as an American National Standard, the Uniform Plumbing Code (UPC) is a model code developed by the International Association of Plumbing and Mechanical Officials (IAPMO) to govern the installation and inspection of plumbing systems as a means of promoting the public's health, safety and welfare.  The UPC is developed using the American National Standards Institute's consensus development procedures. This process brings together volunteers representing a variety of viewpoints and interests to achieve consensus on plumbing practices.   The UPC is designed to provide consumers with safe and sanitary plumbing systems while, at the same time, allowing latitude for innovation and new technologies. The public at large is encouraged and invited to participate in IAPMO’s open consensus code development process. This code is updated every three years. A code development timeline and other relevant information are available at IAPMO’s Website.

The ETL Listed Mark is proof that your product has been independently tested and meets the applicable published safety standard.  Intertek's ETL Mark was born into a culture of innovation. It was in Thomas Edison's lighting laboratories where it all began, and to this day we still breathe the same air of innovation, safety and quality. We also understand a manufacturer's need to get new products to market quickly to achieve the greatest success, therefore we have built speed, responsiveness and urgency into our processes. Our commitment to helping customers gain the certifications they need quickly and efficiently has never been greater.  The ETL Mark is proof of product compliance (electrical, gas and other safety standards) to North American safety standards. Authorities Having Jurisdiction (AHJs) across the US and Canada accept the ETL Listed Mark as proof of product safety. Retail buyers accept it on products they're sourcing. And every day, more and more consumers recognize it on products they purchase as a symbol of safety.
