Its 10-inch length keeps the threaded connection away from walls and helps drain water out of the line, while the multi-turn operation gives precise control over flow. The single-pack design is intended for easy retrofit of sillcocks, hose bibs, and outdoor spigots where a garden-hose threaded outlet is required.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this adapter protect my home's water supply?\u003c\/h3\u003e\n\u003cp\u003eThe anti-siphon design prevents water from being drawn back into household plumbing, which reduces the risk of contaminants entering the potable water line.
