When anticipating freezing temperatures, shutting off the water and opening faucets helps protect your pipes. By closing your home’s main water valve, you will stop the flow of water while letting the air circulate through the pipes.
This reduces the pressure and prevents water from freezing, thus avoiding burst pipes during harsh winter months.
Toilets, hose bibs, and other fixtures can also benefit from having the water shut off. Turning off the water at the main valve and then opening faucets allows trapped air to escape, decreasing the risk of water hammer.
This phenomenon occurs when pressurized air causes pipes to shake, resulting in a loud banging noise. Though this might not seem like a significant issue, it can lead to pipe bursts and water damage over time.
By proactively shutting off your water, you can avoid the need for emergency plumbing services in cases like leaks or broken pipes. Spotting issues early enables you to call a professional plumber and resolve them before they escalate into more severe problems.
Be sure to familiarize yourself with the location of your main water shut-off valve, which typically resides in the basement, garage, or near the water heater.
While turning off the water might seem like a straightforward task, it is crucial to remember that various types of valves require different approaches.
For instance, gate valves require gently turning the valve handle clockwise, while ball valves need to be perpendicular to the pipe handle. A quick checklist or consultation with a plumber can guide you in maintaining your home’s water system.
In warmer climates, be mindful of exterior faucets and their positioning relative to exterior walls. These faucets can be prone to freezing and leakage even in mildly cold temperatures. Similarly, know the location of your water meter along the main water line for easy access in case of an emergency.
Locating Main Water Shut Off Valve
When trying to shut off the water to your home, it’s essential to know how to locate the main water shut-off valve. The valve can be found indoors or outdoors, depending on the setup of your plumbing system. This section will guide you through finding both types of locations.
Indoor Location
In many homes, the main water shut-off valve is situated inside a utility room, basement, or crawlspace. It is a large valve, often with a round wheel handle or lever, that can be turned clockwise to close the water flow.
To help locate the valve indoors, follow these steps:
- Look for where the water pipeline enters your home, typically near the water meter or water heater.
- Trace the pipe back to the main water line that supplies the entire house.
- Locate the valve with the wheel handle or lever and ensure it is accessible.
Remember to ensure clear access to the valve at all times, as you may need to shut off the water quickly in case of emergencies.
Outdoor Location
If the main water shut-off valve is not located indoors, it is likely to be found outside your home. Outdoor locations may vary depending on the local building codes and climate.
Here’s how to locate the valve outdoors:
- Locate the water meter at the front or side of your property, typically near the street.
- Look for a concrete or plastic box with a metal lid covering the meter.
- Open the lid with a meter key or another suitable tool.
- The shut-off valve will be next to the meter – it may have a round wheel handle or a small rectangular piece that requires a wrench to turn.
Once you have found the main water shut-off valve, it’s essential to inform other household members of its location. This will enable them to take action in case of plumbing emergencies when you may not be around.
Types of Water Shut-Off Valves
There are two common types of water shut-off valves that you may encounter when attempting to turn off the water supply in your home: the gate valve and the ball valve.
Both types have specific advantages and applications.
Gate Valve

A gate valve functions by raising or lowering a metal gate to control the flow of water. When the gate is lowered, it seals off the water flow, and when raised, it allows water to flow through the valve. Gate valves are typically found in older homes and can be distinguished by their round or oval-shaped handwheel.
To turn off the water using a gate valve, rotate the handwheel clockwise to lower the gate and cut off the water supply. Although gate valves are durable and reliable, they can be prone to corrosion and may not seal as effectively over time.
One issue you may encounter with gate valves is that they may become stiff and difficult to operate due to infrequent use.
Ball Valve
The ball valve is another type of shut off valve that has become more popular in recent years, especially for new constructions. Ball valves feature a lever handle that is attached to a perforated ball inside the valve.
When the lever is parallel to the pipe, it means the valve is open, and when it is perpendicular to the pipe, the valve is closed.
To shut off the water using a ball valve, turn the lever handle 90 degrees clockwise so that it is perpendicular to the pipe. Ball valves are known for their quick operation, durability, and low maintenance. They are also less likely to experience leakage or failure compared to gate valves.
When shutting off the water to your home, it is important to familiarize yourself with the type of shut off valve you have, as well as its proper operation to ensure a successful water shut off.
When to Leave Faucets Open
It’s important to know when to leave your faucets open after shutting off the water. There are a few specific situations where this practice can be helpful.
One common reason to leave faucets open is during freezing weather conditions. When temperatures drop below freezing, the water in your pipes can freeze as well.
As water freezes, it expands, which can lead to pipes cracking and ultimately bursting. By leaving the faucets open, you allow any remaining water to flow out of the pipes, reducing the risk of freezing and associated damage.
When you’re working on a plumbing project, leaving faucets open can be beneficial as well. Shutting off the water supply and opening the faucets allows the remaining water to drain from the pipes.
This will make it easier to work on the project at hand, as it minimizes the amount of water that may spill out of the pipes when you start to work on them.
Another situation where leaving faucets open is a good idea is when you’re going on an extended vacation, especially during winter months. Shutting off your home’s main water supply and opening the faucets can help prevent potential water damage from frozen and burst pipes while you’re away.
In all these situations, leaving faucets open has added benefits. Allowing air to flow through the pipes can help prevent the build-up of pressure and reduce the risk of your pipes bursting.
It also makes it easier to detect leaks in your plumbing system, as you will notice water flowing from the open faucets if there is still an active leak.
How to Turn Off Water and Drain Your System
Closing Main Water Valve
Before you leave your faucets open, the first step is to locate and close the main water valve. This valve is usually found in the basement, garage, or near the water meter. Turn the valve clockwise (right) to shut off the water supply to your entire home.
Opening Faucets
Once you have closed the main water valve, open all the faucets in your home, both hot and cold. Start with the faucets on the highest floor and work your way down to the lowest level. This will help to release any build-up of pressure in the water lines and allow the water to drain out of the pipes.
Flushing Toilets
After opening the faucets, proceed to flush all the toilets in your home. This will help to remove any remaining water from the tanks and bowls. Additionally, you can pour a small amount of antifreeze into the toilet bowls to prevent freezing during colder months.
Draining Water Heater
Finally, be sure to drain your water heater. To do this, first, turn off the power supply to the unit (either by unplugging it or flipping the corresponding breaker switch). Next, locate the drain valve at the bottom of the water heater and attach a garden hose to it.
Run the hose to a floor drain or outside, and then open the valve to release the water. Be cautious when draining the water heater, as the water may be extremely hot. Remember to also open the pressure relief valve (usually located near the top of the unit) so that air can enter the tank, allowing the water to flow out more efficiently.
Preventing Frozen Pipes

Proper insulation is key to preventing frozen pipes, especially those located close to exterior walls. Insulating your pipes will not only reduce heat loss but also protect them from freezing temperatures.
You can use various materials like pipe sleeves, heat tape, or even newspaper to insulate your pipes. It’s important to focus on pipes in unheated areas like basements, attics, and crawl spaces, as well as those close to exterior walls.
In addition to insulation, it’s a good idea to keep your house at a consistent temperature to prevent freezing. During cold spells, try to maintain a minimum indoor temperature of 55°F, even if you are not home.
Open your cabinet doors to allow warm air to circulate around the pipes, especially if they’re located along exterior walls.
Cold water pipes are more likely to freeze, so let your faucets drip slightly as a precaution. Allowing a small flow of water through the pipes will help relieve pressure and reduce the risk of freezing. When it gets extremely cold, you may also consider leaving the faucets open after shutting off the water.
It’s also important to seal any gaps or openings in your home that could let cold air in, as this can lead to freezing. Check for drafts near your pipes, particularly those running along exterior walls, and use weatherstripping or caulk to address any issues.

Experiencing a plumbing emergency, such as a pipe burst or a severe leak, can be a stressful situation. It is crucial to act quickly to minimize water damage and prevent potential structural issues in your home.
Here are some steps you can follow to handle plumbing emergencies effectively.
First and foremost, shut off the water supply to your home as soon as possible. Locate the main water valve and turn it off to prevent further water leakage or damage. In the case of a localized leak, you can simply turn off the water supply to that particular fixture.
Keeping faucets open after shutting off the water supply is a good practice. This allows any remaining water in the pipes to drain, reducing pressure and minimizing the chances of frozen pipes or pipe bursts. Be sure to open both hot and cold water faucets to help the drainage process.
In the event of a frozen pipe, try gently thawing it with a hairdryer or a portable heater. However, refrain from using open flames, as this can cause a fire hazard. If you notice any cracks in the pipe, shut off the main water supply immediately and call a professional plumber for assistance.
It is essential to regularly inspect your plumbing system for any signs of damage, such as bulging or discolored areas on pipes, as well as the presence of unusual odors or damp areas. Early detection of potential issues can save you from costly plumbing repairs and water damage.
Remember, attempting DIY fixes during a plumbing emergency can lead to greater issues if not correctly executed.
Don’t hesitate to contact a professional plumber for assistance, as they have the expertise and tools necessary to address any plumbing issues efficiently and safely. It’s always better to rely on professional help to achieve long-lasting and reliable solutions for your plumbing emergencies.
Proper maintenance and timely repairs can greatly reduce your risk of facing plumbing emergencies. By following these steps and seeking professional assistance when needed, you can ensure the continued health of your plumbing system and avoid unexpected and potentially costly issues.
Turning Water Back On and Assessing Issues
After shutting off your water and leaving your faucets open, it’s important to know how to properly turn the water back on and assess any potential issues.
Follow these steps to ensure a smooth process.
Releasing Trapped Air
Once you’re ready to turn the water back on, the first thing you should do is release any trapped air in the pipes. To do this:
- Close all the faucets that you left open.
- Slowly turn on the main water supply valve.
- Go to the highest faucet in your home, usually found on the top floor, and slowly open it.
- Once the water starts flowing, open the rest of the faucets in your home one by one, starting at the highest level and working your way down.
This process will help release any trapped air, preventing potential damage to your plumbing system.
Checking for Leaks and Damage
After turning the water back on and releasing trapped air, it’s crucial to inspect your home for any leaks or damage:
