Outdoor faucet: freeze and backflow protection

Treat the hose bibb as a potable-water + freeze + envelope interface with backflow protection and proper winterization.

VERT / GREEN = documenter/entretenir · JAUNE / YELLOW = vérifier avant travaux · ROUGE / RED = arrêter le DIY et faire valider.

Hose left connected in winter
Disconnect and follow the device winterization strategy. No identifiable backflow protection
Verify required backflow protection before risky use. Leak suspected in wall after freeze
