Yes, both Boshart’s 304 Stainless Steel and No-Lead Bronze Slide Type Pitless Adapters are
certified to both NSF/ANSI 61 Drinking Water System Components – Health Effects, and to NSF/ANSI 372 Drinking Water System Components – Lead Content, certification.
61 vs. 372 What is the Difference?
NSF/ANSI/CAN 372 addresses lead content only by establishing a limit on the amount of Pb (Lead) that may be contained within individual plumbing products. The NSF/ANSI/CAN 372 standard includes a formula for calculating the weighted average lead content of each product and specific procedures for lead content testing.
Whereas NSF/ANSI 61 testing specifically verifies and certifies that the materials used to manufacture our Pitless Adapters do not leach harmful chemicals into your water supply, ensuring the water remains safe and hygienic.
To pass NSF/ANSI/CAN 61, the leachate from the testing must have contaminant levels below the total allowed concentrations for each that are deemed safe for human ingestion.
The testing of finished products is performed by exposing them to pH 5 and pH 10 waters at specified temperatures and analyzing the leachate for regulated metals including but not limited to; Al (Aluminum), Sb (Antimony), As (Arsenic), Ba (barium), Be (Beryllium), Bi (Bismuth), Cd (Cadmium), Cr (Chromium), Cu (Copper), Pb (Lead), Hg (Mercury), Ni (Nickel), Se (Selenium), Ag (Silver), Ti (Titanium), Sn (Tin), Zn (Zinc). Products are also exposed to pH 8 water and tested for organic chemical contaminants.
NSF/ANSI 61 Requirements - Acceptance Criteria Regulated contaminants:
- Includes USEPA and Health Canada regulated contaminants and EPA’s health advisories,
non-regulated contaminants. -
More than 600 risk values have been set by NSF to address leaching of chemicals from materials that contact drinking water utilizing procedures outlined in Annex A of NSF 60 and 61.
CAUTION: Compliant Doesn’t Mean Certified
If a manufacturer states a product is “compliant with” or “meets” the NSF/ANSI standards, they are claiming that they adhere to the requirements of the standard, however the product has not been tested by an accredited third party to evaluate, test, and prove that the product meets the requirements.
Certification is not obtained by all who apply! Manufacturers must provide documentation and pass testing by a third party. To gain certification, a manufacturer must:
- Submit an application and information proposal.
- Undergo product evaluation.
- Undergo in-lab product testing.
- Pass a manufacturing facility inspection, production confirmation, and product sampling.
- Test results are reviewed and accepted.
- A contract is signed, and products are listed.
- Maintain annual plant inspection and re-testing.
Certification is not a one-time analysis. It’s an ongoing audit that ensures we as a manufacturer continue to use the processes and materials that meet the high standards that safeguard your water consumption. The last part of the NSF/ANSI certification process is one that should truly put your mind at ease.
Beyond health concerns, there are additional benefits to using our NSF/ANSI 61& 372 certified Pitless Adapters:
- Product meets / exceeds well construction codes, a top-quality product for those
involved in both private and / or municipal water well construction projects. - Municipalities most likely require NSF/ANSI 61 certification for water product components. Currently, 48 states of the United States require NSF/ANSI 61 certification. However, state agencies nationwide can order water producers to remove all non-NSF-certified products, so it’s always best to start with NSF-certified products and avoid potential mandatory replacements or fees.
- A sanitary connection will exist between the Pitless and the Well casing to prevent surface water from contaminating the well water. The Boshart Pitless Adapters are also certified to ASSE Standard #1093-2019 and WSC (Water systems council) Standard PAS-97 (2019).
- Easy to source Standard North American AS568 O-Rings, with the replacement O-ring size molded on the Pitless Elbow casting.
- You will have peace of mind in the integrity of your water system, in regard to quality, performance and safety.
NOTE: Boshart’s Industrial (Spool Type) Pitless Units are also both NSF/ ANSI 61 & 372 certified. Boshart’s NSF/ANSI -61 certification DOES NOT have any limiting factors such as “Minimum Daily GPM Requirements” which may void the NSF certification!
