Overview

Watflow 12 Inch Anti-Siphon Frost-Free Sillcock is engineered for reliable outdoor water performance in cold climates. The design blends frost protection with anti-siphon safety and a durable, lead-free brass body finished in chrome, delivering long-lasting service and potable-water compatibility.

The unit features a 1/2" NPT inlet for a quick, secure connection to your supply line and a 3/4" GHT hose bibb outlet that makes attaching hoses and irrigation accessories straightforward.

Real-Life Use

From early morning garden chores to weekend cleanup, this sillcock provides a reliable water source that resists corrosion and backflow. While no single fixture guarantees frost protection in every climate, the design emphasizes resilience, ease of maintenance, and practical performance across seasonal changes.
