WaterWorker HT-30B Vertical Pressure Well Tank, 30-gallon tank with 26-gallon capacity, Blue

Engineered to comply with the specifications of, and certified by the National Sanitation Foundation (NSF) under ANSI/NSF Standard 61. The Butyl diaphragm features seamless construction and is engineered to flex, avoiding the stretching and creasing typical of bladder tanks. The polypropylene liner for the water reservoir will not flake, chip, crack, or peel, and does not transfer any taste or odor to the water. The diaphragm and liner isolate the water from contact with the deep-drawn steel domed shell, which is twice as strong as a rolled steel shell of identical thickness. A high-gloss enamel finish shields the tank from environmental exposure. Pre-charged to 25 psi. Consult the product guide for the correct pre-charge setting
