Drainage Products Certification

NSF helps manufacturers of drainage products meet all regulatory requirements and plumbing codes throughout the U.S. and Canada. We also provide listings to the Uniform Plumbing Code (UPC) and International Plumbing Code (IPC).

We test drainage products to confirm the accuracy of your stated flow rates and comply with industry standards, including:

• Floor drains (ASME A112.6.3)
• Roof drains (ASME A112.6.4)
• Grease interceptors and septic tanks (ASME A112.14.3, ASME A112.14.4, CSA B481)
• Plumbing waste fittings and valves (ASSE 1049, 1050 and 1051, ASME A112.14.1)
• Cast iron soil pipes and no-hub couplings (CISPI 301, CISPI 310, ASTM A888)

By certifying your products with NSF, you’ll shorten the turnaround time between manufacturing and testing, allowing you to get your products to market more quickly.
