Background Information on Plumbing Standards

Plumbing standards are one key avenue to advancing water efficiency in plumbing fixtures and fixture fittings.  Since 1994, water utilities have become more aware of and involved in this standard-setting process.  The Alliance is one of those interests represented in the processes, and works aggressively to help the evolution toward more efficient products.  There are numerous committees and teams that develop ANSI-approved plumbing fixture standards, such as the following:

  • ASME A112.19.2-2008/CSA B45.1-08 – Ceramic Plumbing Fixtures
  • ASME A112.19.5-2011/CSA B45.15-11 – Flush valves and spuds for water closets, urinals, and tanks
  • ASME A112.19.14-2006 – Six-Liter Water Closets Equipped with a Dual Flushing Device
  • ASME A112.19.10-2003 – Dual Flush Devices for Water Closets (after-market devices)
  • ASME A112.19.19-2006 – Vitreous China Nonwater Urinals
  • ASME A112.18.1-2010/CSA B125.1-10 – Plumbing Supply Fittings
  • ASSE 1002 – Anti-siphon Fill Valves (Ballcocks) for Gravity Water Closet Flush Tanks
  • ASSE 1016 – Performance Requirements for Automatic Compensating Valves for Individual Showers and Tub/Shower Combinations
  • ASSE 1037: Performance Requirements for Pressurized Flushing Devices (Flushometers) for Plumbing Fixtures
  • CSA B45.5-10/IAPMO Z124-10 – Plastic plumbing fixtures
