Water Quality and Health Effects

Overview

Water Quality Testing & Certification

If your plumbing product delivers drinking water or contains a filter, water softener, reverse osmosis unit, or ultraviolet disinfectant (UV) unit, CSA Group provides you with a one-stop-solution of testing and certification solution that includes drinking water, mechanical, and electrical standards. CSA Group evaluates both point-of-entry and point-of-use products, and can test and certify individual plumbing components, such as filter cartridges that reduce lead or chlorine.

CSA Group tests water quality to CSA, NSF and ANSI standards.

For plumbing supply fittings:
  • NSF/ANSI 372 lead testing in drinking water for supply fittings & pipes (should this be “for”)
  • NSF/ANSI/CAN 61 toxicology testing of drinking water for supply fittings & pipes
  • ASME A112.18.1/CSA B125.1 plumbing supply fittings
  • CSA B483.1 and NSF/ANSI 42, 44, 53, 55, and 58 for drinking water treatment units
For electrical plumbing components:
  • C22.2 No. 139
  • C22.2 No. 218
  • UL429 For drinking water
