New Certifications For VIQUA UV Systems

WaterMark Logo VIQUA

It takes more than a quality product and innovation for a company to become a market leader. Understanding regulations in various markets and investing in certifications are also key. We are pleased to announce the WaterMark™ designation.

WaterMark is a certification trademark for water supply, sewerage, plumbing, and drainage products in Australia and New Zealand. The intent of the WaterMark is to help Australian consumers be confident about the quality of the plumbing products they’re purchasing, regardless of whether the goods are manufactured domestically and abroad. We recently applied for and were granted WaterMark certification for the UV systems listed in Table 1.

Having UV systems that are suited to residential flow rates as well as those that handle higher flow rates or offer more technical features gives a wide range of end-users confidence in the VIQUA brand.

Applying for third-party certification is not as simple as making a request or filling in a form. In the case of WaterMark for instance, any manufacturer applying for certification must be willing to:

  • Submit product for performance testing (or produce proof of current validation achieved through a similar certification body, such as NSF);
  • Undergo an initial manufacturing site audit;
  • Demonstrate a high level of document control and maintain quality logs that may be requested for review at any time; and
  • Submit the initial and renewal fees.

For many years now, we have worked with NSF® to achieve and maintain NSF 55 Class A and NSF 55 Class B validations on a variety of our UV systems. NSF is one of the most recognized marks in water treatment.

NSF International is also a very well respected, independent certification organization. These are the folks who actually develop the standards to which water treatment products are tested. When a UV system is NSF certified, it means the UV system complies with the strict standards and procedures imposed by NSF, including extensive product testing and material analyses. But, in addition, as the manufacturer, VIQUA is also subjected to unannounced plant inspections and regular re-testing of our products to maintain the NSF certification. It is not a one-time event, it’s an ongoing review process. NSF certification is recognized by regulators at all levels, from local and state to federal and international.

Sometimes you may encounter a product that is described or labelled as “NSF validated”. This means that the product was tested by a third party to the standards established by NSF, but the actual testing of the product was not done by NSF, nor is NSF inspecting that manufacturer’s facility to ensure continued product quality and performance. Not really the same thing.

Lastly, we know that water treatment continues to grow in importance in emerging markets, too. In China, the Ministry of Health (MoH) has established its own standards for water treatment products, and we are in the process of securing certification for various UV systems that best meet the needs of that market. The first of these received MoH approval in September of this year and include the following residential UV systems:

  • IHS12-D4/CHN
  • IHS22-D4/CHN
  • IHS22-E4/CHN
  • VT4-DWS11/CHN
