The B & K 1/2 in. x 10 in. Anti-Siphon Frost-Free Sillcock Valve provides reliable outdoor water access while protecting the domestic water supply from freezing and backflow contamination. Engineered with a quarter-turn ceramic cartridge for smooth operation, it features an integrated backflow preventer to stop siphoning and drains automatically upon water shut-off when the hose is removed or open. Constructed with a heavy chrome-plated brass body and lead-free silver solder, this sillcock valve offers exceptional corrosion resistance and durability. The notched flange ensures stable installation against exterior siding, while precision-manufactured connections provide secure attachment to plumbing supply lines and standard garden hoses.
