Pentair makes equipment that moves, treats, and manages water. Its main products include water filtration systems, pumps, and flow control equipment sold to homeowners, pool owners, industrial facilities, and commercial buildings. The company is one of the larger dedicated water treatment and management businesses in the world, with well-known brands like Pentair Pool and Everpure.

Pentair earns money by selling hardware, replacement parts, and filtration consumables — the consumables create repeat purchases over time, which helps stabilize revenue. The company operates primarily in North America and Europe, generating roughly $4 billion in annual revenue. Its competitive edge comes from brand recognition, a large installed base of equipment that needs ongoing maintenance and replacement parts, and deep distribution relationships. The key growth driver is rising global demand for clean water solutions, but the main risk is exposure to housing and construction cycles, which can sharply reduce demand for residential pool and water treatment products during downturns.

Cash watch

Pentair has less than a year of cash at its current burn rate. Growth investors should watch for potential share dilution from future fundraising — that directly reduces your ownership.

The Winston Score above measures business quality today. Growth stocks often score lower because they invest in the future rather than maximising current profits. These metrics show what matters most for evaluating that future.
