The Pro-Source steel pressure tank from Sta-Rite Industries Inc. features a pressurized water-system performance cycle. The tank’s seamless, one-piece water cell provides controlled two-dimensional expansion, with compressed air around the water cell allowing water to be drawn from the tank. Chlorine- and iron bacteria-resistant, its design prevents water from contacting metal. Electrostatically-applied polyester paint gives an appliance-quality finish and is engineered to be resistant to nicks and corrosion. Leak tested with helium before shipment, this steel pressure tank is available in both horizontal and vertical models and comes with a five-year warranty. Sta-Rite Industries Inc.
