Third party listing of geothermal piping systems provides engineers, regulators and users the assurance that products are independently certified to meet requirements for geothermal end use. Third party certification reduces potential liability, increases confidence and product acceptance, and helps to ensure product consistency in meeting all applicable requirements.
NSF/ANSI Standard 14 is the American national standard for plastic piping system components and related materials and provides a major benefit by establishing the minimum physical, performance and health effects requirements for the plastic piping components. NSF/ANSI 14 establishes product testing, long-term strength and quality control requirements that are key to ensuring product performance in the field.
