B & K 1/2 in. x 12 in. Anti-Siphon Frost-Free Sillcock Valve

The B & K 1/2 in. x 12 in. Anti-Siphon Frost-Free Sillcock Valve delivers reliable outdoor water control with outstanding freeze protection. Built with a heavy-duty chrome-plated brass body and a smooth quarter-turn ceramic cartridge, this valve offers effortless operation, excellent flow rate, and exceptional resistance to corrosion. Equipped with an integrated backflow preventer, this sillcock stops siphoning back into the potable water supply. The valve automatically drains upon shut-off when the hose is detached or open, preventing freezing and burst pipes during colder seasons. A notched flange ensures stable installation against exterior siding.
