Pentair

Pentair traces its roots to 1966, when founders Winslow Partridge and Murray Harpole started the company in St. Paul, Minnesota. The name combines penta, a reference to the five original investors, with air, reflecting the company's early line of air-filled novelty products. Over the following decades the company moved away from novelty goods and built a portfolio of industrial businesses through a series of acquisitions.

A turning point came in 1997 with the acquisition of the water treatment and pump businesses of General Signal, followed by the 2004 purchase of WICOR, which brought the Sta-Rite and Hypro brands into the Pentair family. After spinning off its electrical business in 2018, Pentair narrowed its focus to water related products, with operations centered in the Minneapolis area.

Product Lines

Pentair's portfolio carried by SupplyHouse spans water treatment and conditioning equipment, pumps for residential and light commercial applications, and pool and spa equipment. Well pumps, sump and effluent pumps, booster pumps, and water filtration and softening components make up the core of the lineup that contractors source for potable water and drainage projects. Pressure tanks and control valves round out the systems used to deliver consistent water pressure and quality in homes and small commercial buildings.

Why Contractors Specify Pentair

Plumbing and water treatment contractors turn to Pentair because the brand's pump and filtration lines are built around decades of acquired engineering expertise from companies like Sta-Rite and Hypro. Replacement parts and compatible components remain available across product generations, which simplifies service calls on older systems already in the field. A broad lineup covering pumps, tanks, and filtration also lets contractors source matched system components from a single brand rather than piecing together parts from multiple suppliers.

How to Choose Pentair Products

Selecting the right Pentair pump or filtration component starts with matching flow rate and pressure requirements to the specific application, whether that is a private well, a sump pit, or a booster system for a multi-story building. Water chemistry and intended use, such as potable water versus irrigation, determine whether a filtration or conditioning unit is the better fit. Confirming voltage, horsepower, and tank capacity against the existing plumbing layout helps avoid a mismatched installation and a return trip to the supply house.
