Legend introduces a series of new quarter-turn commercial sillcocks equipped with an integral vacuum breaker (ASSE 1011): the T-547 rough brass, T-548 satin-finished brass and T-549 chrome-plated brass commercial sillcocks. The valves are ideal for high-frequency use in residential and commercial applications. The T-547, T-548 and T-549 are actual ball valves; therefore they are easier to actuate, have improved flow and greater longevity than traditional multi-turn sillcocks.
