Pentair is a pure-play water company: it makes the pumps, filters, salt chlorinators and heaters that run residential swimming pools, the softeners and filtration systems that clean home and commercial water, and the industrial and commercial pumps that move it. After spinning off its electrical business as nVent in 2018, it became a focused water-treatment compounder selling mostly through distributors like Pool Corp, Leslie's and the big-box retailers.

From steel and motors to a working pool

Pentair buys steel, plastics, electric motors and filtration media, turns them into pumps, filters, heaters and softeners, and then almost never sells direct — distributors like Pool Corp and Leslie's and retailers like Home Depot carry the products the last mile to pool builders and homeowners.
