Water Pik
An American oral-care brand best known for water flossers and other personal-care products.
Last updated August 31, 2026
Overview
Water Pik is an American oral-health and personal-care brand whose best-known products are oral irrigators, commonly marketed as water flossers. The brand traces its origins to 1962, when Aqua Tec Corporation introduced an oral irrigator using a pressurized stream of water to support cleaning between teeth and along the gumline. This product established the core technology and product category with which Water Pik would later become associated. The company’s corporate history has included several major ownership and business-portfolio changes. Aqua Tec was acquired by Teledyne in 1967. In 1999, the business was separated from Teledyne as a public company under the name Water Pik Technologies. At that stage, the company was broader than a conventional oral-care brand: it operated personal-care activities and also marketed swimming-pool and related equipment under brands including Water Pik, Jandy, and Air Energy. In 2006, Water Pik Technologies was acquired by the private-equity firm The Carlyle Group and the French company Zodiac in a transaction reported at approximately $380 million. The company had six major facilities in the United States and Canada at the time. Its pool-equipment activities were subsequently reorganized with Zodiac’s marine and pool operations. In 2007, the pool division was combined with the marine and pool business to create Zodiac Marine & Pool, headquartered in Paris. The Jandy pool business remained associated with that pool-equipment operation rather than the later consumer oral-care business. The separation of the pool activities was an important step in narrowing the Water Pik identity around personal and oral health. In 2013, Zodiac Marine & Pool and EG Capital sold their interest in the remaining Water Pik business, excluding the pool-equipment division, to MidOcean Partners and Vulcan Capital. The company was reported to have approximately 1,400 employees in 2012, although that figure belongs to the wider business before or during the period of portfolio separation and should not be treated as a current employee count. In 2017, Church & Dwight agreed to acquire Water Pik from MidOcean Partners. The transaction announcement described Water Pik as generating approximately $265 million in revenue for the fiscal year ended June 30, with around 70 percent attributed to water-flosser products. Those figures relate to the reported transaction period and are not a current financial measure. Following the acquisition, Water Pik became a subsidiary within Church & Dwight’s consumer-products portfolio. Water Pik’s product range has developed from the original oral irrigator into a broader oral-care assortment. It has included countertop and cordless water flossers, electric toothbrushes, replacement components, and combination devices such as the Sonic-Fusion line, which combines brushing and water-flossing functions. The brand has also sold pulsating showerheads and replacement showerhead products. Its current historical identity is therefore rooted in oral irrigation, while its corporate past also encompasses pool and spa equipment that was separated from the oral and personal-care business before the Church & Dwight acquisition.
History
Water Pik began in 1962 as Aqua Tec Corporation, a company formed around the development of an oral irrigator. The device used a pulsating, pressurized stream of water rather than conventional floss to help clean between teeth and around the gumline. This invention provided the foundation for the Water Pik name and for the company’s later specialization in home oral-care appliances. Teledyne acquired Aqua Tec in 1967. Under Teledyne ownership, the business developed beyond its original oral-irrigation roots and eventually operated as part of a wider personal-care and equipment portfolio. In 1999, Water Pik Technologies was spun off as a public company. The publicly traded company manufactured personal-care products and swimming-pool products, using brand names that included Water Pik, Jandy, and Air Energy. The company changed ownership again in 2006, when The Carlyle Group and Zodiac acquired Water Pik Technologies in a transaction reported at approximately $380 million. At that point, Water Pik had six major facilities across the United States and Canada. The transaction brought the business into a broader private-equity and industrial-products ownership structure, while retaining both its personal-care and pool-equipment activities. The pool business was reorganized separately from the oral-care business. In 2007, the pool-equipment division was combined by Carlyle and Zodiac with Zodiac’s marine and pool division, creating Zodiac Marine & Pool with headquarters in Paris. The pool portfolio included the Jandy brand and other swimming-pool equipment activities. This restructuring reduced the extent to which the Water Pik corporate identity depended on pool products. A further ownership change took place in 2013. Zodiac Marine & Pool and EG Capital sold their interest in the remaining Water Pik operation, excluding the pool-equipment division, to MidOcean Partners and Vulcan Capital. The resulting business was more closely associated with oral and personal care than with its earlier diversified equipment portfolio. A 2012 report placed employment at approximately 1,400 people, although the historical figure relates to the broader business around the period of the portfolio changes. In 2017, Church & Dwight agreed to acquire Water Pik from MidOcean Partners. Contemporary reporting cited approximately $265 million in revenue for the fiscal year ended June 30 and indicated that roughly 70 percent of that revenue came from water-flosser products. These figures were transaction-period disclosures rather than a continuing public financial series. The acquisition placed Water Pik within Church & Dwight, a consumer-products group, and made the brand part of a larger portfolio of household and personal-care businesses. Water Pik’s product development has remained centered on oral irrigation. Its assortment has included countertop and cordless water flossers, electric toothbrushes, replacement parts, and combination products. The Sonic-Fusion series combined electric brushing with water flossing in one system. The brand has also produced pulsating showerheads and replacement showerheads, reflecting the company’s historical involvement in water-directed personal-care products. Pool and spa brands associated with the earlier Water Pik Technologies portfolio, including Jandy, belong to the separated pool-equipment history rather than to the core oral-care business acquired by Church & Dwight.

Products and positioning
A specialist oral-care brand positioned around water-based interdental cleaning and home-use personal care.
Waterpik water flossersOral irrigators1962
Water flossers are the brand’s defining product category. They direct a controlled, pressurized stream of water between teeth and around the gumline for home interdental cleaning. The historical range has included countertop units connected to a water reservoir as well as more portable cordless formats. These products developed directly from the oral irrigator introduced by Aqua Tec in the 1960s.
Electric toothbrushesOral care
Water Pik’s oral-care range expanded beyond water irrigation to include electric toothbrushes. These products broadened the brand’s role from a specialist interdental-cleaning provider into a more complete home oral-care supplier, while remaining complementary to the water-flosser line.
Sonic-FusionCombination oral-care system
Sonic-Fusion is a combination brushing-and-flossing system that integrates electric brushing with water-flossing functionality. The line reflects Water Pik’s effort to combine two daily oral-care actions in one appliance rather than treating brushing and interdental cleaning as entirely separate routines.
Pulsating showerheadsPersonal care
The company’s historical personal-care assortment also included pulsating showerheads. These products extended the brand’s use of directed water flow beyond oral care and formed part of the wider Water Pik product portfolio before and after the company’s major ownership changes.
Replacement showerheadsShower products
Waterpik has sold replacement showerheads under the Waterpik name. They represent a continuing connection to the brand’s water-directed personal-care heritage, although oral irrigators remain the company’s most distinctive and commercially important product category in the historical record.
Jandy and related pool productsPool equipment
Water Pik Technologies historically marketed swimming-pool and related equipment through brands including Jandy and Air Energy. These activities were later separated from the personal-care business and combined with Zodiac’s marine and pool operations. They are therefore part of the company’s corporate history rather than the core Water Pik oral-care assortment.
