Drinking water applications

NSF/ANSI 61 (NSF 61) approval is required for potable (drinking) water applications to ensure that materials and components do not leach harmful contaminants into the water. Here’s why it is important:

1. Health & safety – NSF 61 ensures that products in contact with drinking water do not introduce lead, heavy metals, or other harmful substances that pose health risks.
2. Regulatory compliance – Many state and local regulations mandate NSF 61 certification for components used in public and private water systems to meet EPA and Safe Drinking Water Act requirements.
3. Material suitability – Certification verifies that the materials used in pipes, valves, fittings, coatings, and other water system components do not degrade or contaminate the water supply.
4. Product reliability – NSF 61-approved products undergo rigorous testing for chemical leaching, structural integrity, and long-term performance in water systems.
5. Customer & industry requirements – Many municipalities, engineers, and industries require NSF 61-approved products for water treatment plants, plumbing systems, and food and beverage applications to ensure safety and reliability.

In addition to the NSF approval, the SUH sanitary flow meters also achieve FDA, 3A, and EC 1935/2004 approvals making them suitable for various sanitary applications.
