How does an outdoor water spigot work?
A standard outdoor spigot has a compression valve, and the entire fixture is no more than 4 inches long from spout to water connection. When you mount one on the side of the house, the supply pipe is close to the wall, making it the most vulnerable part of the faucet and the part most likely to freeze and burst.
What makes an outdoor faucet frost-free?
A frost-free faucet is a hose bibb with a longer rear connection, “essentially a pipe that’s preconfigured to the valve body,” O’Brian explains. With a frost-free faucet, when you turn the water off the remaining water in the pipe (up to the shutoff valve) drains out so no water is left in the pipe to freeze.
How do frost-free hose bibs work?
When you shut off the water on a frost-free faucet, the water stops behind the valve, which is set further back inside the home. This means the water won’t freeze because it stays where the interior air temperature is warmer.
What do you do with outdoor water spigots in the winter?
Here’s what you can do to help prevent a watery disaster from striking in the middle of winter!
- Close the shut-off valve for the faucet. From the inside of your home or building, close the shut-off valve that controls the flow of water to the outdoor faucet(s).
- Disconnect your hoses!
- Drain the faucet.
How does a frost proof water spigot work?
This is the anatomy of a frost proof spigot. AKA “Sillcock”. It works by shutting off the water inside your home and allowing the water to run out of the actual faucet so that there is nothing to freeze.
How does a frost free outside faucet work?
To keep the pipe between the shut-off valve and the faucet outside from freezing, a sillcock pipe is drained through a small hole known as a petcock to keep it free of water for winterization. In the older-style faucets, the riser simply drained back down into the water line, creating a back-flow.
How does an antifreeze spigot on an outdoor faucet work?
The compression valve in an antifreeze spigot works in exactly the same way as the one in a regular outdoor spigot. When you turn the handle clockwise, a screw mechanism compresses a stopper with a rubber washer onto the water inlet port to stop the water. Unscrew the handle and the valve loosens, allowing water to flow.
How does a frost proof water line work?
Frost-proof systems house the valve further up the pipe (ideally, inside the house wall—away from the frost). The vacuum, or anti-siphon assembly is what prevents water from your hose backing up into the line and your home water supply.
