What is NSF-61?


NSF-61 is a set of regulations that covers products that come in contact with drinking water in the USA including pipes, hoses, fittings, gaskets, adhesives, coatings, lubricants, faucets, drinking fountains, filters, water meters, valves, filters, and more.

Basically, if it comes in contact with potable water, NSF-61 verifies that it is safe.

Why is this important? Flint, MI provides a cautionary tale of what can happen when unsafe products come in contact with drinking water.

An Unsafe Drinking Water Catastrophe
In 2014, Flint changed its water source from Lake Huron to the Flint River. Insufficient water treatment caused lead from old and unsafe water pipes to leach into the water delivered to local homes and businesses. The lead pipes in Flint were installed many years before water-safety regulations restricted their use, but the problems didn’t affect citizens until the water source and water treatment changes. Current estimates for fixing these problems range as high as $1,500,000,000.

NSF-61 helps prevent such disasters by ensuring that all components of the water system are certified safe for contact with potable water, preserving the quality and safety of drinking water.

NSF-61 Certification: Good For Water Systems, Good For Citizens
NSF-61 certification has broad benefits for both water systems and consumers. Residents can have peace of mind that the water coming out of their tap is safe to drink.

These regulations are also good for water systems. NSF-61 provides a universally accepted, 3rd-party verification that the pipes, gaskets, and meters utilized for water delivery are drinking water safe. This minimizes the liability faced by water systems and decreases the likelihood of costly repairs and updates in the future. NSF-61 certified components can cost a little more on the front end, but water systems recoup this investment by eliminating the need to dig up pipe to repair or replace sub-standard and unsafe components.
