Preventing water pipes from freezing and bursting at home requires some basic knowledge and preparation.
You can start by locating your home's shut-off valves, which are usually found near the water meter or where the water line enters your home.
Insulate exposed pipes in unheated areas like the garage, basement, or crawlspace to prevent them from freezing.
Disconnect and drain hoses from outdoor faucets to prevent water from freezing in the hoses and causing damage to the faucets.
If you live in an area prone to freezing temperatures, consider installing freeze-proof faucets or frost-proof spigots, which are designed to prevent water from freezing in the pipes.
Understanding the Risks
Frozen pipes pose a significant threat to your home's plumbing system, as water expands when it freezes, putting immense pressure on the pipes containing it. This pressure is what causes frozen pipes to burst or crack, leading to water damage and potential flooding.
Pipes are most susceptible to freezing when exposed to severe cold temperatures, especially in exterior hose bibs and faucets, exterior walls, and unheated interior spaces like attics, basements, and crawl spaces. Poor insulation or areas experiencing unusually cold weather can increase the risk.
The temperature alert threshold is 20° F, especially if you have uninsulated pipes running through an uninsulated space. This means you should take measures to keep your pipes warm and water running once the temperature starts dropping outside.
Why Freeze
Pipes are most susceptible to freezing in certain areas of your home, such as exterior hose bibs and faucets, exterior walls, and unheated interior spaces like attics, basements, and crawl spaces.
These areas are particularly vulnerable to cold temperatures, which can cause the water inside the pipes to freeze.
Poor insulation in your home can increase the risk of pipes freezing, as it allows cold air to penetrate and reach the pipes.
Outdoor pipes, especially those without proper insulation, are especially at risk of freezing.
In areas that experience sudden cold snaps, the risk of pipes freezing is even higher, as a rapid drop in temperature can quickly lead to frozen pipes.
Underground septic systems can also freeze, causing pipe issues for homeowners.
Here are some common areas where pipes are most susceptible to freezing:
- Exterior hose bibs and faucets
- Exterior walls
- Unheated interior spaces (attics, basements, crawl spaces)
The Dangers of
The pressure inside a frozen pipe can be likened to a ticking time bomb.
The danger is not when the pipe freezes, but when it thaws, and the full force of city water pressure can cause significant water damage in a short time.
A ruptured pipe can lead to extensive water damage, soaking through walls, floors, and ceilings, potentially causing structural damage alongside the immediate repair costs.
The resulting water damage can be swift and devastating, making it crucial to take preventative measures to protect your home.
Will Freeze?
Water will freeze at 32 degrees, so technically that is the temperature at which it becomes possible for pipes to freeze as well. Pipes can freeze at 32 degrees or below, however the temperatures need to remain at or below freezing for a sustained period of time.
It's unlikely a pipe will freeze unless you are experiencing freezing temperatures for at least half a day before. And, scientifically speaking, the temperature will need to be well below 32 for at least that length of time before pipe freezing becomes likely.
If you're wondering how long it takes for pipes to freeze, the answer is that it depends on the temperature. But as a general rule, pipes are unlikely to freeze unless the temperature stays below freezing for at least half a day.
Preventing Freezing
Frozen pipes are no joke. They can cause serious water damage and even lead to flooding.
Pipes are most susceptible to freezing when exposed to severe cold temperatures. This commonly occurs in exterior hose bibs and faucets, exterior walls, and unheated interior spaces like attics, basements, and crawl spaces.
The risk increases in homes with poor insulation or in areas experiencing unusually cold weather. Outdoor pipes are particularly vulnerable, especially those that are not insulated properly.
To prevent pipes from freezing, keep your heating system running, even if you leave for a period of time. Keeping your home thermostat set above 50 degrees Fahrenheit should provide enough heat to keep the pipes warm.
Locate pipes at risk of freezing and add insulation to them. High-risk zones include the garage, crawl space, attic, unfinished basement, and other unheated or poorly insulated areas indoors.
Outdoor plumbing should also be protected, if possible. Disconnect garden hoses and drain your sprinkler system. You don't want water trapped in there, waiting to freeze and expand.
Seal cracks and other holes in your exterior walls, including those around any light fixtures, outdoor electrical outlets, and phone or cable lines coming into your house. Drafts from these openings can not only chill the pipes in your walls but also waste your heating budget!
Here are some key steps to prevent frozen pipes:
- Insulate pipes located in the attic and crawl space using pipe insulation.
- Seal or caulk any cracks that might let in cold air.
- Disconnect garden hoses and drain your sprinkler system.
- Keep water moving through your water system by letting the cold water drip from a faucet served by exposed pipes.
If you plan to be away during cold weather, leave the heat on in your home, set to a temperature no lower than 55° F. This will help keep your pipes from freezing and prevent costly repairs.
Preventive Measures
Protecting your home from frozen pipes is a top priority during the winter months. Keeping your heating system running is a great place to start.
Setting your thermostat above 50 degrees Fahrenheit should provide enough heat to keep pipes warm. This is especially important if you're going to be away from home for an extended period.
Locate pipes at risk of freezing and add insulation to them. High-risk zones include the garage, crawl space, attic, unfinished basement, and other unheated or poorly insulated areas indoors.
Pipe insulation can be found at your local hardware store, and it comes in various R-values. The higher the R-value, the better.
Disconnect garden hoses and drain your sprinkler system to protect outdoor plumbing. This will prevent water from becoming trapped and freezing.
Seal cracks and holes in your exterior walls to prevent drafts from chilling your pipes. This will also help you save on your heating budget.
Opening cabinet doors below kitchen and bathroom sinks can help heated air reach the pipes inside. This is especially important if you're concerned that heated air isn't reaching the pipes.
Turning your faucets on just enough to slowly drip can help reduce pressure in the pipes and prevent rupture. This is a simple yet effective measure to take during the winter months.
Here are some key steps to take when learning how to keep pipes from freezing:
- Insulate pipes in the attic and crawl space using pipe insulation or heat tape.
- Seal or caulk any cracks that might let in cold air.
- Disconnect garden hoses and drain outdoor faucets.
- Keep water moving through your water system by starting a small drip in your faucets.
- Alert a friend or neighbor if you'll be away for an extended period.
Protecting Indoor Pipes
Protecting indoor pipes is crucial to preventing water pipe bursts. Indoor pipes, especially those in unheated areas or exterior walls, need protection from freezing temperatures.
To insulate exposed pipes, use foam pipe insulation on both hot and cold water pipes in areas such as attics, basements, crawl spaces, and garages. Cut the insulation to size with a utility knife and secure it around the pipes.
Maintaining proper home temperature is also essential. Keep your thermostat set to the same temperature both day and night, as fluctuating temperatures can create optimal conditions for pipes to freeze and thaw, increasing the risk of bursting.
Here's a list of high-risk areas for pipe freezing:
- Attics
- Basements
- Crawl spaces
- Garages
By following these simple steps, you can significantly reduce the risk of indoor pipe freezing and bursting.
Protecting Indoor Pipes
Keep your heating system running, even if you leave for a period of time. Keeping your home thermostat set above 50 degrees Fahrenheit should provide enough heat to keep the pipes warm.
Locate pipes at risk of freezing and add insulation to them. High-risk zones include the garage, crawl space, attic, unfinished basement, and other unheated or poorly insulated areas indoors. Your local hardware store should have pipe insulation, or pipe sleeves, as well as outdoor spigot covers and other insulating products. The higher the insulation's R-value, the better.
Seal cracks and other holes in your exterior walls, including those around any light fixtures, outdoor electrical outlets, and any phone or cable lines coming into your house. Drafts from these openings can not only chill the pipes in your walls but also waste your heating budget!
Open the cabinet doors below kitchen and bathroom sinks if you're worried heated air isn't reaching the pipes inside.
If you have pipes in unheated areas like the garage or crawl space, consider relocating them or adding more insulation. This can be a costly but effective solution in the long run.
Here are some high-risk zones to focus on:
Turn your faucets on just enough to slowly drip. Most pipes burst between an ice blockage and the faucet, not between the blockage and the source of your water supply. Opening up the faucet reduces the pressure in the pipe, hopefully enough to avoid a rupture.
Installing Frost-Proof Faucets
Installing frost-proof faucets is a great way to prevent frozen pipes in your outdoor plumbing. These faucets have a longer stem that extends into the heated area of your home, preventing freezing at the valve seat.
Frost-proof faucets with PEX piping are recommended for homes in cold climates. They are engineered to protect your home by keeping the water shut off inside where it's warmer.
The initial cost of a frost-proof faucet may be higher, but it provides substantial peace of mind by significantly reducing the risk of frost-related plumbing problems.
Protecting Indoor
Protecting indoor pipes requires attention to areas that are prone to freezing temperatures. Indoor pipes, especially those in unheated areas or exterior walls, also need protection from freezing temperatures.
To prevent pipes from freezing, you should keep your heating system running, even if you leave for a period of time. Keeping your home thermostat set above 50 degrees Fahrenheit should provide enough heat to keep the pipes warm.
Locate pipes at risk of freezing and add insulation to them. High-risk zones include the garage, crawl space, attic, unfinished basement, and other unheated or poorly insulated areas indoors. Your local hardware store should have pipe insulation, or pipe sleeves, as well as outdoor spigot covers and other insulating products.
Seal cracks and other holes in your exterior walls, including those around any light fixtures, outdoor electrical outlets, and phone or cable lines coming into your house. Drafts from these openings can chill the pipes in your walls and waste your heating budget.
Here are some common areas to check for proper insulation:
- Attics
- Basements
- Crawl spaces
- Garages
Cut the insulation to size with a utility knife and secure it around the pipes. Investing in high-quality insulation for pipes can save substantial costs in repairs and water damage by keeping them at a stable temperature above freezing.
Know Master Valve Location
Knowing where your master water shut-off valve is located is crucial in case of an emergency. It's usually found near the water meter or where the water line enters your home.
If you can't find it, check your home's plumbing diagram or contact a plumber for assistance. They can help you locate it.
In some cases, the master valve is located outside, so make sure to check both inside and outside your home.
