ProLine 104-829HC Sillcock, Anti-Siphon, Frost-Free, 1/2 X 12 In.

The ProLine 104-829HC is a frost-free anti-siphon sillcock designed for reliable outdoor water access in freezing climates. This 1/2-inch by 12-inch valve combines backflow protection with automatic drainage to prevent ice damage and safeguard your home's water supply. It connects to your water line via 1/2-inch male inlet and 1/2-inch solder connection, with a 3/4-inch hose thread outlet for standard garden hose attachment.

Frost-free sillcocks solve the problem of frozen outdoor faucets by draining water automatically when you shut off the valve and remove or open the hose. The built-in backflow preventer stops contaminated water from siphoning back into your home's plumbing system—a critical safety feature for any outdoor faucet.
