KOHLER is committed to developing high-quality bathroom products which improve the lives of kiwis, and customers around the world.

Concern and awareness of heavy metals (including lead) in household water supply is growing as water networks age, and consumers demand higher quality.

Our products are independently tested to ensure they meet or exceed international standards.

Product testing

All KOHLER kitchen & basin mixers sold in New Zealand are independently tested, Watermark certified, and comply with the following standards:

  • AS/NZS 3718-2005 Water supply – Tapware
  • AS/NZS 4020-2018 Testing of products for use in contact with drinking water
  • AS 2345-2006 Dezincification resistance of copper alloys
  • AS/NZS 3499-2006 Water supply – Flexible hose assemblies
  • AS/NZS 6400-2016 Water efficient products – Rating and labelling

AS/NZS 4020-2018 is of particular relevance as it specifies a maximum allowable lead concentration of 10 µg/L.

The only exception to this testing schedule above is our new KOHLER Malleco Touchless Kitchen Mixer, which complies with the following standards:

  • GB 18145-2014 Ceramic Cartridge Faucets
  • AS/NZS 6400-2016 Water efficient products – Rating and labelling

GB 18145-2014 specifies a maximum allowable lead concentration of 5 µg/L. This is the same as US standards, and is more stringent than New Zealand’s standard (AS/NZS 4020-2018).

Live with Confidence

Kiwis can be confident that KOHLER tapware exceeds New Zealand’s water safety standards.

KOHLER has a strong commitment to water quality and water conservation, in addition to the independent testing, KOHLER has received multiple awards for water conservation by the US Environmental Protection Agency (EPA).
