Protecting an outside faucet (also known as a frost-free sillcock, hose bib, or spigot) from freezing is crucial to prevent damage to your plumbing system. Here’s a comprehensive guide on how to do it, covering different scenarios and methods:
I. The Best Prevention is Frost-Free Faucets (If You’re Installing or Replacing):
If you have the opportunity to install a new faucet or replace an old one, opt for a frost-free sillcock. These are designed to prevent freezing and are the most effective long-term solution.
* How they work: Frost-free sillcocks have the shut-off valve located inside your warm house, usually several inches back from the outside wall. This means water drains out of the pipe exposed to the cold when the faucet is turned off.
* Installation: This type of faucet requires a longer pipe and needs to be installed with a slight downward slope from the inside shut-off valve to the outside opening.
II. Protecting Existing Faucets (If Not Frost-Free):
If you have standard outside faucets that are not frost-free, you’ll need to take specific steps before freezing temperatures arrive.
A. The Most Important Step: Turn Off the Water Supply to the Faucet
1. Locate the Shut-Off Valve: Inside your house, find the valve that controls the water supply to your outside faucet. This is usually in:
* Basement: Near the wall where the faucet exits.
* Crawl Space: Similar to the basement location.
* Utility Room: Especially if the faucet is near a sink or laundry hookup.
* Furnace Room: Sometimes associated with the main water line.
* Unfinished Toilet Room: If the faucet is on that side of the house.
2. Turn the Valve Off: Turn the valve clockwise until it stops. This will shut off the water supply to the specific faucet.
B. Drain the Faucet and Associated Pipes
1. Open the Outside Faucet: Go outside and turn the handle of the outside faucet completely on. This will allow any remaining water in the pipe to drain out. Leave it open.
2. Open Other Faucets (Optional but Recommended): To help relieve pressure and ensure complete draining, it’s a good idea to turn on some of your interior faucets (hot and cold). This isn’t strictly necessary for just the outside faucet, but it helps the overall system depressurize.
3. Check for Drainage: You should see water flow out of the outside faucet. Keep it open until no more water comes out.
C. Insulate the Faucet (Once Drained)
This is the next crucial step after shutting off and draining.
* Faucet Covers (Insulated Sleeves):
* Where to buy: Hardware stores, home improvement stores, online retailers.
* Types: They are typically made of foam, fiberglass, or a tough plastic with insulating material inside. Some have an outer shell that is water-resistant.
* How to use: Slip the cover over the entire faucet spout and handle, and secure it snugly. Many have Velcro or ties for a tight fit.
* Considerations: Make sure the cover is large enough to completely enclose the faucet.
* Insulating Wrap (Bubble Wrap, Foam Pipe Insulation):
* How to use: You can wrap the faucet and the exposed pipe leading to it with layers of bubble wrap or foam pipe insulation. Secure the insulation tightly with duct tape or zip ties.
* Waterproofing: Since this is on the *outside*, it’s essential to add a layer of waterproofing over the insulation. Heavy-duty plastic sheeting, tarps, or even thick garbage bags can be used. Wrap this material around the insulation and tape it securely to prevent moisture from getting in (which could freeze and damage the insulation).
* Trash Bag Method (Temporary and Less Effective): In a pinch, you can stuff a plastic grocery bag with insulation material like crumpled newspaper or rags and tie it around the faucet. However, this is not as reliable as a dedicated faucet cover or proper insulation.
D. Disconnect Hoses (Very Important!)
Never leave a garden hose connected to an outside faucet when temperatures are expected to drop below freezing.
* Why it’s important: When a hose is connected, water can be trapped in the faucet’s valve and the hose itself. If this water freezes, it will expand, cracking the faucet, the pipe, or even your wall.
* Action: Always disconnect and store your garden hoses indoors for the winter. Make sure there’s no water left in the hose.
III. Special Considerations and Tips:
* Know Your Faucet Type: If you’re unsure whether your faucet is frost-free, assume it’s not.
* The “Drip” Method (Less Recommended for Extended Cold): Some people suggest leaving a faucet (even a non-frost-free one) on a very slow drip during freezing weather. This is not a reliable method for prolonged cold spells and can waste water. It’s better to shut it off and insulate.
* Check for Leaks: Before winter sets in, check your outside faucet for any drips or leaks. A small leak can become a big problem when frozen.
* Regular Maintenance: Even with frost-free faucets, it’s a good idea to disconnect hoses and check them periodically.
* Extreme Cold: In regions with extremely harsh and prolonged winters, you might consider having a professional plumber install a more robust winterization solution, such as using a shut-off valve with a drain, or upgrading to multiple frost-free faucets.
* DIY Frost-Free Installation: If you’re handy, there are DIY kits to convert standard faucets to frost-free, but it requires some plumbing knowledge.
In Summary: The Triple Threat!
1. Shut off the water supply.
2. Drain the faucet and pipe completely.
3. Insulate the faucet and exposed pipe.
4. Disconnect all hoses.
By following these steps, you can significantly reduce the risk of your outside faucet freezing and causing costly damage to your home’s plumbing.
