What are the benefits of the Quadra-Hull® tank?
Culligan’s Quadra-Hull® tank is one of the strongest water tanks available on a water softener. The exclusive four-layer construction of the Quadra-Hull tank provides more protection than industry standard fiberglass and metal tanks. This design makes them impervious to rust and corrosion and they are UV resistant. Culligan’s Quadra-Hull tanks offer a limited lifetime warranty on the tank and internal components. Your Culligan Dealer can show you more about the dependable construction on every Culligan water softener.
