How A Standard Frost-Proof Faucet Works
The product is designed to be frost-proof when installed properly (with a slight downward pitch) and there is no restriction on the hose nozzle to prevent the faucet from draining. If a hose is attached during freezing weather, water is trapped inside the faucet which may cause the faucet to freeze and burst.
When the faucet’s valve in the closed position, the water is shut off several inches into the home. The water line does not freeze because of the heat in the home. The product cannot freeze because there is no water in the faucet. When the valve is turned off, all of the water in front of the valve drains from the faucet leaving the tube empty. Also shown is correct and incorrect installation and a frozen split tube condition when hose is left on during freezing weather.
When a hose or other restriction is left attached, the water cannot drain from the faucet properly. As the temperature drops below freezing, the water in the faucet begins to freeze. The freezing conditions are applied from the outside of the house back toward the interior as the water continues to freeze. Once the water has frozen into the faucet itself, if the faucet has been shut off, there is no relief from this expanding pressure. Eventually the copper tubing will burst to relieve the pressure. No noticeable damage is visible in the home at this time. Only a few drops of water will leak through this bulge at the time of the bursting. Once the weather warms, the ice in the faucet will melt. Since the burst in the tubing is after the shut off valve, water will not leak out of the burst tubing until the water is turned on. Thus, there can be a considerable amount of time between the actual rupture of the tubing and the discovery of the problem.
