Do you need shut-off valve for outdoor faucet?
Exterior faucets should have a separate shutoff valve inside the house, but not all of them do. In older homes, these valves are typically located at the ceiling somewhere close to the outside faucet. In newer homes, the valves are typically located right next to the main water valve, and they're also usually labeled.
Your home's outdoor water shut-off valve is usually located near the ceiling, on the inside of the wall where the outdoor faucet is located. If the outdoor shut-off valve is tap- or knob-style, turn it clockwise, or to the right, to shut it off (remember: righty-tighty, lefty-loosey).
You can leave the faucets open until next spring. Do your faucets have a back-flow preventer? You'll need to disconnect it to the let the water drain. Pipe insulation is your best friend if your faucets don't have shut-off valves.
The best way to prevent damage to water lines during winter is by turning off outside faucets. Regardless of whether your water lines are freeze proof or not, removing hoses and splitters from the spigot during cold weather can save you from a lot of trouble.
The freeze-proof faucet has a handle and spout outside the house like any spigot. That links to a long pipeline, which has a shutoff valve or stop valve at the other end. The pipe is usually at least 4 inches long and sometimes longer to reach far enough into the house to keep the water in warm temperature levels.
If your outdoor faucet does not have a shut-off valve, first disconnect any hoses or attachments from the faucet. Then, turn off the main water for your home and open the faucet to purge any remaining water in the line. Once this is done, close the faucet valve and turn the water back on.
At what temperature does an outside faucet freeze? An outside faucet will freeze when the outdoor temperature reaches 28ºF (-2ºC) or lower, so it is well worth keeping an eye on night time temperatures in particular as fall progresses, as early frosts often happen at night or in the early morning.
Cover the outdoor faucets before the temperature dips below freezing. Especially when the temperature dips below 28 degrees and you think that your outdoor faucet will not be able to survive such freezing temperature, then it's best to cover them fully with recommended faucet covers.
When temperatures dip to 28 degrees or below, and the outside faucets freeze, ice can form in the water supply pipes that lead to those exposed outdoor faucets. If your outdoor faucets aren't properly prepared for winter, water damage from frozen pipes may occur.
Although interior pipes are generally safe at temperatures as low as 20℉ (-7℃), outdoor faucets can freeze as long as temperatures are at or below 32℉ (0℃) for at least 6 hours.
Is it OK to leave outdoor faucet on?
