When it comes to your water heater, things might get a little crazy.They may begin to leak, or a digital alarm (if the water heater is equipped with one) may begin to ring if the water heater begins to fail.Maybe you’re in a state of panic because the water heater alarm is going off or because a geyser of water is threatening to destroy your home or other property.The first step is to switch off the water heater.

Do you, on the other hand, know how?Here’s how to quickly and securely switch off your water heater, including how to turn off the electricity to the water heater.

How to Turn Off Your Water Heater

  • Use the instructions below to securely and efficiently turn off your water heater in the safest and most effective manner. The following are the actions to take in order to switch off your water heater: Remove the electricity from the source
  • Turn off the water supply.
  • Take care while draining your water heater.
  • Circuit breakers should be clearly labeled.
  • Walk through the process of turning off your water heater before you need to

We will go into further depth about each of these procedures to switch off your water heater further down in this section…

1. Turn off the power source

This step must be completed first in order to avoid injuring yourself or damaging the heater.Depending on whether or not you have an electrical unit, you must shut down the circuit breaker for your hot water heater (it will either be located on your main circuit breaker panel or, less often, near the heater itself).If you have a gas unit, turn the dial near the thermostat to the ‘Off’ position.Before proceeding with the next procedures, it is critical to turn off the breaker for your hot water heater or turn off the dial on the thermostat.

To ensure your hot water heater is not damaged, switch off the circuit breaker for it using either your main circuit breaker panel or a panel near the water heater, depending on how your water heater is configured.Please do not hesitate to call us if you require assistance in locating the breaker panel or the dial to a gas unit.

2. Turn off the water

Only proceed with this step if you are certain that the power to your water heater has been turned off.The Best Way to Turn Off Your Hot Water Heater It’s possible that your water heater has several distinct sorts of handles on it.If you find a circular handle on the valve, turn the handle clockwise to shut off the water supply line.It will be linked to the cold water input on the water heater.

Once it is completely closed, but not overtightened, no more water will enter the heater; nevertheless, your sinks and tubs will continue to have access to cold water, and they will continue to receive warm water until the heater is completely emptied.The water supply for your entire house might be turned off if you cannot locate the water connection for the heater.After opening the box, you will need to spin the valve nearest to your house (which is often outside your home and near the curb in newer suburbs), and after doing so, you will need to seal the box again.

3. Drain your water heater carefully

You will find a drain valve at the bottom of the tank, which may be used to connect the tank to a home.Connect it to your tub drain, a floor drain, or an exterior drain where the hot water will not harm people or damage your lawn.Using the drain valve, you may evacuate water from your tank once it has been properly installed.Draining your tank is an additional step beyond simply turning off your water heater, but it is necessary if your digital read-out suggests it or if you notice a leak from the body of the water heater that you can stop by draining the tank.

Once you’ve turned off the electricity and turned off the water, any damage that a damaged water heater would have caused has been mitigated, and you can either call a specialist or begin looking for the source of the problem.Even after you have turned off the power, the tank will still be full with scorching hot water, so empty it carefully and avoid coming into touch with it; the temperature will remain high for several hours after you have turned off the power.

Label your circuit breakers

Many circuit breakers regulate numerous things at the same time, and the sequence in which they do so is not always obvious.Labeling your breakers ahead of time is the easiest method to prepare yourself in the event that you need to completely shut down the electricity in your home or the electricity to a specific device immediately.If the previous owner labeled your circuit breakers, go ahead and check them to make sure they are accurate; believing that you have turned off the electricity to an item or a section of your home when you have not is dangerous.

Walk through shutting off your heater before you have to.

When an alarm goes off or when someone notices a leak spreading over the floor, everyone experiences a brief moment of terror and disorientation.If you practice shutting off your water heater, you will be more familiar with any oddities or unusual processes your water heater has before you need them.If you keep your water heater in good working order by emptying it every three to six months, you will be even more comfortable in the case of an emergency water heater failure.Also, make sure to turn the water back on in your residence when you’ve finished.

If you open the valve too much or too rapidly, it might break the connection and cause anything to move out of place.If you are unfamiliar with how to operate your main water valve, ask the plumber to demonstrate the proper process when they arrive to inspect your heater.Make a note of where your shut-off valves are located.

This recommendation, similar to the one for a circuit breaker, is applicable to more than just your water heater.It is critical to understand how to securely shut off water to various appliances, as well as how to safely shut off water to your entire home.When you have a leak, you don’t want to waste time hunting for it; but, the main water valves might be difficult to locate at times.

If you are unable to switch off your water heater or if you require the services of a professional, you can reach out to here or call 1(888)393-1772 for emergency assistance in the tri-state region.

How to Turn off the Water for Plumbing Repairs

When doing plumbing repairs on any of the fixtures or pipelines in your home’s plumbing system, it is frequently essential to turn off the water supply to the whole building.There are at least three distinct areas where you may turn off the water, and which one you choose will depend on the location of the leak or the necessity for plumbing repair.In most cases, no special equipment are necessary to turn off the water.Here are many sites where your home’s water supply may be turned off, as well as instructions on how to select the most appropriate one.

Watch Now: How to Turn Off Water for Plumbing Repairs

Turning the Water off at the Fixture or Appliance

  • Whenever a faucet is dripping or a toilet is flushing—or whenever there is a leak develops in a refrigerator, ice-maker, dishwasher, washing machine, or any other appliance that is supplied with water—the first and best course of action is to turn off the water at that fixture or appliance. By cutting off the water locally in this manner, other fixtures linked to your home’s plumbing system will be able to continue to work while you do the necessary repairs elsewhere. The shut-off valves for fixtures and appliances will vary in appearance and placement, but in general, they will be located fairly close to the fixture or appliance. Sink faucets have shutdown valves that are positioned below the sink, near where water supply tubes flow up to the faucet’s tailpieces. The valves on any faucet that distributes both hot and cold water will be two in number: one for the hot water supply and another for the cold water supply.
  • A single shut-off valve will be installed on the bottom of the toilet tank (a toilet utilizes only cold water), which is often positioned near the floor below the water supply valve on the top of the toilet tank. When it comes to toilet tanks, this supply valve is often located at the bottom left side of the tank.
  • Look around the tub or shower for an access panel if you have a shower or a tub. A toilet may be located on the other side of a wall from a bathtub or shower. When an access panel is not found, it is possible that it is hidden beneath the floor in the basement or that it is hidden behind a ceiling access panel on the floor below.
  • When it comes to dishwashers, the water supply tube that runs to the dishwasher is frequently controlled by a fixture shutdown valve. The small copper or mesh supply tube that runs to the refrigerator usually has a small saddle valve or fixture shutoff valve that can be turned off to turn off the water supply. For refrigerator ice makers/water dispensers, the small copper or mesh supply tube that runs to the refrigerator usually has a small saddle valve or fixture shutoff valve that can be turned off to turn off the water supply. Occasionally, the supply tube leading to the refrigerator may connect to a water supply line beneath the sink, at the point at where both the refrigerator and sink faucet supply tubes are connected.
  • When it comes to clothes washers, the water supply valves that regulate the hot water input hose and the cold water inlet hose are most commonly found in the same location. It’s possible that your laundry has a utility sink, in which case the valves are positioned on the utility sink, or that your laundry has a recessed water supply valve box built into the wall near the washing machine.

You get the gist of it. It is recommended that each fixture or appliance be provided with some type of local shut-off valve. However, if you are unable to locate the shut-off valves, do not be concerned. Turning off the main water supply valve, which is located near the water meter, will switch off the water supply.

Turning the Water off at the Main Shutoff Valve

You should locate the main shut-off valve for the house if your leak originates anywhere in the main branch line, or if there is no fixture shut-off valve near the fixture that needs to be repaired or replaced.Most of the time, this may be located in a utility space near where the main water line enters the home, or on an outside wall near the water meter.This valve will always be positioned on the same side of the house as the water meter, and it is often a rather large valve in comparison to the others.Because this valve is rarely closed, it may feel a touch stiff when you turn it.

If you open the lowest faucet in your home (such as a basement faucet or a foundation-level outside faucet) and the highest faucet in your home after shutting off the main shut-off valve, it will enable water that has accumulated in the plumbing system to drain away.Because the water supply pipes will be completely devoid of water before you begin working on them, there will be no risk of water leaking out when you begin.


There are branch valves installed in certain residences that may be used to cut off the water supply to specific branch lines within the residence.It is planned that these valves will be installed along the major branch pipes and in easily accessible utility locations.For example, water lines that feed outside hose faucets are frequently controlled by in-line valves that solely regulate the pipes that go to the outdoor faucets and nothing else.

Turning the Water off at the Water Heater

When a hot water pipe leaks, or if you need to repair or replace a water heater, shut-off valves installed near the water heater can be used to turn off the water supply.A water heater is equipped with two shut-off valves.A cold water input valve (typically distinguished by a blue handle) is responsible for supplying cold water to the water heater from the main supply.If you need to repair or replace your water heater, this is the valve to turn off.

The hot water output line is also equipped with a valve that prevents any hot water from leaving the water heater from flowing out.This valve can be turned off if there is a leak in a hot water line someplace in the house, as this valve is responsible for controlling all hot water in the house.This valve is frequently identified by a red handle, which indicates that it regulates hot water.

This easy color coding is necessary since the cold water input pipe and the hot water outflow pipe are frequently located quite near to one another and would be difficult to distinguish if not for the color coding.

Turning the Water off at the Water Meter

Finally, you might be able to turn off the water directly at the water meter.Water meter boxes may include two shutdown valves, one on the customer side of the meter and the other on the municipal side, depending on the manufacturer.The usage of this method should only be used as a last option since in many areas, homeowners are prohibited from accessing any portion of the plumbing system located on the street side of the water meter.Because the plumbing lines beyond the meter are legally the property of the city, you should avoid touching this valve unless you have no other choice—for example, if the main shut-off valve on the house side is either non-existent or not functioning.

5 Simple Steps to Turn Off Water Heater

Gas or water leaks are some of the things that might cause the most anxiety in a person.However, if you know how to switch off a water heater, you won’t have to worry about this all of the time.When you hear your digital alarm go off, now is not the moment to worry or do anything stupid.Even before you hire a plumber, you must switch off all of the utilities to prevent a gas or water leak from spreading.

How to Turn Off Water Heater

It is possible to be terrified by a gas or water leak, among other things. Fortunately, if you know how to switch off a water heater, this isn’t always the situation. When you hear your digital alarm go off, it is not the time to worry or do anything foolish. Turning off everything, even before calling a plumber, is essential in stopping a gas or water leak.

Step 1. Disconnect from the Power Source

The first step is to locate your water heater’s power source and disconnect it from the grid. If there is an electric unit, make certain that the circuit breaker is turned off before proceeding. When dealing with the gas unit, look for the dial that is next to the thermostat and turn it in the other way.

Step 2. Turn the Water Off

This procedure should not be performed until you are certain that the electricity connection to the water heater has been switched off fully.When purchasing an electric tankless water heater or a propane tankless water heater, several types of handles will be provided for your convenience.Some handles are circular, and all that is required to switch them off is a little rotation to the right of the handle.With this operation, you allow cold water to flow into the sink and tubs, and hot water will no longer be available to those fixtures.

If you are unable to locate the location where the water supply is linked to the heater, switch off the water supply to the entire home.Navigate to a valve near the meter and flip it in the other way by removing the box and turning it back.

Step 3. Carefully Drain the Water in the Tank

Check the bottom of the tank to see if there is a place where you can attach a hose to drain the water.Insert the hose’s other end into a floor drain or a bathtub until all of the hot water has been drained.To find out if there is any special advice concerning safety when draining water, carefully read the product handbook.The first step in figuring out how to switch off a hot water heater is to cut off both the electricity and the water supply.

By doing so, you may reduce the likelihood of any potential harm that leaks or a faulty propane gas water heater may provide to you.When draining the tank, use extreme caution to prevent splattering hot water on yourself.

Step 4. Label Your Circuit Breaker

It is possible that the content of your circuit breaker is complex and ambiguous.This will need the use of labels to ensure that you are aware of the original position of each component.In the event of an emergency, and you are forced to turn off the power totally, those labels will be quite useful.If you have a circuit breaker that has already been labeled, carefully inspect each component to discover its purpose.

You don’t want somebody to assume you shut off the electricity when you actually did not.

Step 5. Practice Shutting Off Water Heater

When their heater leaks or their alarm goes off, the majority of individuals worry and get befuddled.The only way to avoid this confusion is to be aware of how to switch off the water heater in advance of when it is needed.Maintaining the practice of emptying your water heater every six months will help you become more familiar with the procedure.Make a practice of turning on and off the hot water heater supply that runs throughout the entire house.

Become adept at opening the valve carefully, since twisting it too rapidly might exacerbate the situation.If you’re not sure how to go about it, seek for assistance from a professional plumber in your area.This understanding is also applicable when it comes to cutting off the water supply to all of the appliances in your home.

A little frequent practice can help you to overcome the feelings of terror that you may encounter in an emergency.When your water heater is heating, you will not want to make the situation worse by not knowing how to switch it off when it is heating.

How to Turn Off a Gas Water Heater

It is essential that you learn how to turn off a gas water heater if you have a tankless gas water heater in your house. To have it done correctly, follow these simple steps.

Step 1: Turn Off the Water Heater Valve

You will see a red or black button on the front of the tank if you look closely.These buttons are sometimes buried under insulating materials, and you must remove the insulating material in order to show the button.The switch should be moved or turned from the ″on″ position to the ″off″ position.When you turn off the heater, the pilot light will cease operating and the burner will stop heating.

Remove the heat shield and inspect the inside for evidence of heat or flames before replacing it.If you’re performing maintenance, switch on the pilot light; the flame will remain lighted, but the burner will not function.

Step 2: Turn Off the Line that Supplies Gas

If you wish to go outside and hear the heater hissing, turn off the gas line valve before you leave the house.Simply go to the heater and turn off the gas valve that is situated on the gas line near the heater.The lever should be perpendicular to the gas line when it is fully extended.If you can’t locate any valves, follow the gas line until you come to a handle that functions as a switch for the light.

Gas line valves are usually straightforward to find, and you won’t have to spend much time looking for them.However, if you are unable to locate it, consult a competent plumber.

Step 3: Shut Down the Water Heater

If you’re going to be away from home during the winter, make sure you drain the water from the tank to prevent it from freezing.Turn off the water heater and leave it off for 12 hours to enable the water to cool and prevent scalding from occurring.You drain your tank, be sure to do the following: Make sure you have a bucket underneath the pressure release valve so that the water flows directly into the bucket.Open the relief valve to enable the steam to escape, and then gently release the lever to close the valve completely.

Connect a hose to the drain valve, which is situated near the bottom of the tank.Pull the hose to the specific location where you want the water to drain from.In most cases, the draining region should be located at a higher elevation than the water tank’s location.

You should drain the water into your garden if you have one if you have a home with a garden.Pouring water out of the faucets requires turning off the cold water valve and turning on the hot water taps.Allow for complete drainage of the water by keeping the drain valve open until the water is completely gone.

After that, close all of the faucets in the home that are now open.Alternatively, if the water does not drain, it is possible that mineral deposits have accumulated in the drainage channels.Close the valve and then remove the hose to ensure that all deposits have been removed.

Reattach the hose and turn on the valve one more to complete the process.

How to Turn Off an Electric Water Heater

When it comes to turning off your electric water heater, the five actions listed below are helpful. Follow the instructions and you will discover how to switch off your water heater in your house.

Step 1: Turn Off the Breaker

Locating the two-pole circuit breaker is the first step in figuring out how to switch off an electric water heater.It has a current of around 30 to 50 amps and is generally labeled.Even if you have turned off the electric water heater, it is always a good idea to cut off the electricity at the breaker panel.If the breaker is equipped with lock-out lugs, secure them to the breaker.

If you are concerned that you will make a mistake, identify the breaker with paper tape to prevent this from happening.Keeping everyone in the house informed about what you are doing at any given time is also a smart idea.They should refrain from getting close to the service panel or the water heater until you are finished with them.

As a precaution, check the interior of the lid with a non-contact voltage tester to ensure there is no heat trapped within.When replacing the water heater element, it is dangerous to expose yourself to electric shock or high temperatures.

Step 2: Put a Tag on the Breaker

Safety regulations require that you label everything you are working on in order to prevent anyone from being injured.When working with electricity, it’s best to keep the area closed off to prevent prospective victims from entering the area.Mark the location and the equipment to serve as a warning to anyone who might unintentionally walk too close to the site.When it comes to the home, simply turning off the breaker isn’t adequate because everyone is exposed to the same hazard.

The use of identification and restrictions to notify family members about potential threats would be extremely beneficial..While it is not necessary to imitate building site protocols, it is necessary to ensure that everyone is safe.Don’t take the concept of safety lightly because even a single electrocution can result in death.

Take practical efforts to ensure that the heater and the breaker are entirely disconnected from the power source.Putting paper tape on the breaker and labeling it ″Do Not Touch″ is another technique to ensure safety.Anyone who takes the time to read the warning will stay away from the dangerous area.

Step 3: Cool Off the Water

Before you begin any repairs, you will need to let the water in the tank to cool down.It is advisable to switch off the heater in order to prevent the water from being overheated.Set aside some time for the water to gently and gradually cool on its own.You should avoid attempting to chill the water by adding cold water to the container.

Simply turn on a faucet in your home and let it to flow for an extended period of time.After some time, the water should feel lukewarm, which indicates that it is okay to begin your repairs.Once the repair is complete, switch on the water heater and allow the water to heat up as normal for around 15 minutes.

Before using hot water for showering, laundry, or dishwashing anywhere in the house, wait one hour.

Step 4: Turning Water Off

Water tanks should always be equipped with a shut-off valve located on the outlet outside the home’s perimeter.The tank’s placement prevents it from accumulating an excessive amount of internal pressure.When working on the hot water tank, make sure to turn off the cold water supply.If your tank has two valves, locate the one that allows cold water to enter and shut it off completely.

When facing the tank, the valve is normally on your right as you stand facing it.Normally, two valves should not be found on a single supply line, therefore use caution when doing this task.Feel the pipes with your hands to see whether there is any water flowing through them.

The cold line is used for cold water, while the hot pipe is used for hot water, as the name implies.Alternatively, you might choose to switch on a water faucet in your home.The hot water supply line is the one that vibrates as the water flows out of the faucet.

Make a label for the cold line to serve as a reminder of which valve should be kept closed at all times.

Step 5: Drain the Hot Water Tank

As you learn more about how to switch off the hot water heater supply, you’ll come across a few interesting facts.It is possible to carry out various chores without having to empty the water tank.While changing or testing the thermostat or monitoring the power supply unit, you can leave the tank at its maximum capacity of 80%.Draining the water is required before doing activities such as removing or replacing an element or flushing sediments.

The accumulation of deposits in the bottom part of the tank might have an impact on the heating of the water in that section.Before emptying and making repairs, turn off the water heater and allow it to cool down completely.

Wrap Up

  • A few things will become apparent as you begin to learn how to cut off the hot water heater’s supply. Some operations can be completed without the need to empty the water tank. Leaving the tank full while setting or testing the thermostat or monitoring the power supply unit is OK. It is necessary to empty the water before to doing tasks such as replacing the element or flushing sediments. When deposits accumulate in the tank’s bottom section, the water’s ability to heat might be compromised. Before emptying and making repairs, turn off the heater and allow the water to cool.

Should I Turn Off the Water Heater if the Water Is Off?

When you turn off your water line, cold water will cease flowing into your house completely, and if your water heater has a tank, the tank will stop replenishing with cold water when the water line is turned off.In the event that your water is turned off for an extended length of time and you use a lot of hot water, you run the danger of sustaining catastrophic harm.If your water is shut off for a lengthy period of time, such as during a vacation, you should switch off your water heater.If you have a tank-type or hybrid water heater, you should turn off your water heater when the water is turned off.

Keep your water heater turned on until the cold water begins flowing again if you are shutting down only for a brief period of time.Various types of water heaters will be discussed in this article, as well as how they are connected to a water line and what to do if you need to shut off your water or encounter a cutoff for whatever reason.

How Water Heaters Work

Water flow into your house is completely stopped when your water line is cut off, and if your water heater includes a tank, the tank will cease replenishing with cold water when your water line is shut off.You run the danger of sustaining major harm if your water is turned off for extended periods of time and your hot water is used extensively.If your water is shut off for a lengthy period of time, such as during a vacation, you should switch off your water heater.If you have a tank-type or hybrid water heater, you should turn off your water heater.

Keep your water heater turned on until the cold water begins flowing again if you are shutting down for a brief period of time.Various types of water heaters will be discussed in this article, as well as how they are connected to a water line and what to do if you need to shut off your water or encounter a cutoff of any kind.

Tank-Type Heaters

Tank-type water heaters are the most common form of water heater on the market.Essentially, it is comprised of an insulated tank filled with water that is placed above or beside a gas or electric heating device to provide warmth.The cold water enters the tank from the bottom and rises when a gas flame or an electric element warms the water to the surface.A pressure relief valve prevents the heater from being overly pressured if the pressure rises too high.

When a hot water appliance or faucet is required, the water tank pumps hot water out of the tank through the top of the tank and replaces it with new, cold water at the bottom of the tank, as shown.Despite the fact that this process is repeated indefinitely, tankless heaters might occasionally struggle to keep up with strong demand for hot water.Tank-type heaters also use energy continually in order to keep the water in the tank warm even when it is not needed, making them less efficient than certain other heating methods.

Tankless Water Heaters

Because they do not store water, tankless water heaters are significantly smaller than traditional tank-type heaters.It instead waits for a hot-water tap or appliance to demand warm water before activating an electric element or gas burner and drawing cold water directly over the heating mechanism and to where it is required.Despite the fact that tankless water heaters last far longer and provide an unending supply of hot water, they are significantly more expensive to acquire, install, and maintain than tank-type water heaters.

Hybrid Water Heaters

However, they consume more energy than a tankless water heater, which is the most energy-efficient option available. On the surface, the hybrid works by storing water in a tank coupled to an air compressor, which uses air temperature to catch and transmit heat to cold water instead of a gas flame or electrical parts.

Point-of-Use Heaters

These tiny and compact heaters are typically used in conjunction with the main water heater to provide hot water on demand.Point-of-use heaters are often put at fixtures that are far away from the main heater in order to prevent the need to run the water and wait for the water to warm up before using it.These electrically driven machines heat the water instantly, so removing the need for a waiting period.Point-of-use water heaters often last a long time and can be installed quickly and simply, but they cannot be used to replace a home’s primary water heater due to their smaller size.

How the Home Water Line Works

You may find the location of your water main by looking for a 12″ to 112″ pipeline that runs near your water meter if your home is linked to the city’s water system.The presence of an emergency shutdown valve, which would cut off all water flowing into your plumbing system, is also possible, although it is not guaranteed.It is possible that your home is connected to a water well, in which case your system may appear somewhat different, but the function will be the same.The water that enters your house through the main water line has been pressured, allowing it to move through your pipes against gravity, saving you time and money.

This implies that water may flow very rapidly, whether it comes from a faucet, a hose, or a burst pipe in the event of a disaster such as a flood.If you do experience a burst pipe, it’s critical to utilize your emergency stop valve to prevent extensive flooding from occurring.A separate drainage system is used to remove water from the house, generating a flow that transports wastewater to a sewage treatment plant or septic tank through pipes.

The Water Line and the Water Heater

It is important to note that the water entering your home is chilled and passes through cold water pipes. An inlet line from the water heater is connected to one of these pipes. Your water heater is also connected to a hot water line, via which water is sent to various appliances and faucets. Whenever water is required, it is fed into and out of the heater.

What Happens to the Water Heater When Your Water Is Turned Off?

Cold water ceases flowing into your plumbing system from the outside when you turn off your water, which means that your tank-type or hybrid heater will no longer be able to replenish with more water.If the water is turned off for a lengthy period of time and the tank is completely depleted, it is necessary to turn off the water heater to prevent damage to the tank and other components.Unless your water heater is nearly full or completely full, you should not be required to turn it off during a short-term water disconnection.As tankless and point-of-use water heaters do not operate on a continuous heating element or keep water in a storage tank, they do not need that the water supply be disconnected from the mains.

When to Turn Off Your Water Heater

  • In the event of a plumbing emergency, such as when your cold water line loses pressure and fails to fill the water tank, or when your water tank empties for any other reason, it may be essential to turn off your water heater temporarily. It may also be beneficial, but not required, to turn off your water heater in some circumstances, such as when there is a leak. Leaks can occur for a variety of causes, including the following: The following factors contribute to high pressure and high temperature: improper drainage, old age, and damaged tank.
  • In order to save money by not operating the water heater while it is not in use, it is preferable to lower the temperature of the water heater rather than totally shutting off the system. Turning back on a water heater may be a challenging task, and you may find yourself without hot water for a longer period of time than you’d prefer. You should proceed with caution and ensure that you are familiar with the components of your water heater before making any alterations if you decide to turn off your water heater. The following are the components of a water heater: The shutdown valve, which is normally positioned outside and above the water heater, is responsible for stopping the flow of cold water into the device.
  • The drain valve is normally found towards the bottom of the tank and is responsible for emptying the water and sediment from the storage tank.
  • Using a pressure release valve, you can ensure that the pressure inside the tank stays below acceptable limits.
  • If you are concerned about an empty tank following a water shutdown, the heating mechanism, which may be either gas or electric, is the most critical portion of the tank to switch off.

In order to switch off your water heater, follow the steps outlined in the video below:


In the majority of circumstances, you will not need to turn off your water heater if the water is turned off. The water heater must be turned off only in the unusual event that you have had your water cut off for a lengthy period of time and have used up all of the water in the tank of your water heater. Call a skilled plumber whenever you’re in doubt.

How to guide

Isolating Water to Appliances

It’s possible that isolation valves have been installed in your home.This means that you may switch off the water supply without having to turn off any other electrical outlets as a result.Isolating valves are actuated by either a lever or a screw head and are installed on the pipes going up to the appliance, such as a washing machine or a dishwasher, to prevent the appliance from being damaged.

Mains Water Supply (Direct Feed)

Turning off the main water supply to the home may be accomplished at the main stop cock or stop valve, which is often placed under or near where the kitchen sink is located.Using this method, the mains water will be shut off up to the shutoff cock.However, if you have a cylinder, for example, keep in mind that you may also need to switch off this device at this time (see below).The stop valve should be easy to locate and turn off from the street if you know where you are looking for it.

It might be difficult to locate, but it is usually on the pavement and in close proximity to your home if you look for it.These are often covered and marked with a symbol.We recommend that you check with the water board first since you may unintentionally cut off the water to your neighbors, and you may also require a special key for this purpose.

Water Supply (Indirect Feed)

Many individuals switch off the mains, but often neglect to turn off any additional water sources that are fed indirectly by the mains as well.It is possible to store water in the loft and use it to feed water to the bathroom and other areas of the house, such as the kitchen and laundry.The valve that supplies the cylinder or cistern outlet supply must be turned off in order to turn this off.

Hot Water Supply

It is necessary to understand the difference between direct and indirect feed boilers because there are many different types of boilers such as combi, regular, and system.If you have a combi boiler, the hot water is provided directly to the boiler, and therefore closing the mains stop valve will turn off the water supply to the boiler.But if you have a hot water cylinder, this will be an indirect supply since there will be a valve on the line that runs from the cold water storage cistern to the hot water cylinder to shut off the water flow.Eventually, you’ll need to locate and switch off this device.

Central Heating Systems

During the process of draining down your central heating system, you will need to stop it from refilling, and depending on the sort of system you have, there are a variety of ways to do this.The water level in a vented system is maintained by the feed and expansion cisterns, so if you drain down this sort of system, you will need to temporarily shut off the water supply.Either lock up the valve on the incoming line to the cistern or tie up the float valve to keep the water from leaking out into the tank.An unopened filling loop will feed new water to the system and will remain closed unless the system requires topping up.

It should be kept closed and only turned back on when it is necessary to refill the system.

Emergency Water Shut Off

Do you have a leaking water pipe?By shutting off the water, you can prevent or reduce water damage.There are various locations where you can switch off the water: A leaking water heater is one option, but so is a leaking plumbing fixture, or the main water line to the home is another.Depending on where your water leak is located, you should follow the steps in this guide accordingly.

We’ve also included an instructional video to lead you through the process for your convenience.

How To Turn The Water Off At The Leaking Water Heater

  1. Shut off the water heater by turning off the gas or electricity supply. The off setting is reached via clockwise rotation of a knob on the top of a gas water heater’s thermostat. The water heater’s thermostat is positioned near the bottom of the appliance.
  2. For electric water heaters, go to your circuit breaker panel and locate the breaker for your water heater
  3. turn it to the off position. For gas water heaters, use the same procedure as above.

Turn off the water supply valve. Turn the lever on the water shutoff valve counterclockwise until the water stops flowing. This valve is normally found on the right side of the cold line, on the top of the water heater, on the hot line.

  1. Drain The Water Heater If Necessary To Avoid Water Damage
  1. Connect a garden hose to the drain faucet, which is situated at the bottom of the water heater, and let it drain.
  2. Extend the hose to a lower area where hot or corrosive water will not cause harm.
  3. Drain the water heater by turning on the drain faucet. As water drains from the home, open a hot water faucet in the house to allow air to circulate into the water heater.

How To Turn The Water Off At The Leaking Plumbing Fixtures

  1. Then, at the leaky plumbing fixture, turn off the water supply by turning the lever on the water supply shut off valve clockwise until it comes to a complete stop. This valve is often found on the flex line or feed pipe that connects to the plumbing fixture in which it is installed. It might be directly behind or directly below the fixture (i.e. toilets, sinks, washing machine). In the case of leaking sinks, turn off the hot and/or cold water pipes as necessary.
  2. Turn off the water supply line if your toilet is leaking or overflowing.
  3. If your washing machine, dishwasher, or refrigerator is leaking, switch off the feed lines first.

Some situations, such as when the supply valve is not easily accessible or when the leak occurs before the shut off valve, will necessitate the shutting off of the main water supply.

Should I Turn Off My Water Heater When It’s Not in Use?

In order to conserve money, many homeowners inquire as to whether they should switch off their water heater between usage. After analyzing the figures, we came up with a professional response. The answer is no, unless you’re planning to leave on a month-long or longer trip, you shouldn’t switch off your water heater. The reason behind this is as follows:

  1. The amount of energy saved will be little.
  2. By continuously turning off and on your water heater, you will just exacerbate the situation.

Instead, if you’re just going to be gone for a short period of time (less than a month), we recommend simply lowering your water heater’s thermostat down or into the ″vacation″ setting. We’ll go through all of our recommendations above (as well as some other energy-saving suggestions) in further detail below…

Two reasons not to turn your water heater off

1. You won’t see significant savings

  • Following certain calculations, we discovered that the average Phoenix homeowner will only save the following amounts: By turning off their gas water heater, they can save around $0.76 per day
  • by turning off their electric water heater, they can save approximately $1.36 per day.

Please keep in mind that we utilized the Water Heater Energy Cost Calculator from to arrive at the figures presented above.We used the average electric and gas prices in Phoenix as a starting point and assumed a 60-gallon gas water heater with an EF of.67 and a 60-gallon electric water heater with an EF of.92.Your particular savings will vary based on your hot water consumption, the efficiency of your water heater, and the rates charged by your local utility company.But unless you’re planning a month-long (or longer) trip, the savings you’ll accrue from turning your water heater on and off will be insufficient to compensate for the inconvenience of dealing with some of the difficulties you may experience.

This takes us to the second point…

2. You’ll just create more problems

  • In the event that you switch your water heater off between uses and then back on again within a short period of time, you will encounter the following difficulties: When you return, there will be no hot water. After returning from your vacation, you’ll be met by a tank of lukewarm water, which will come as a rude surprise when you go into the shower. According to your water heater, you might be waiting anywhere from 20 minutes to over an hour for hot water
  • difficulties turning the unit back on
  • and other issues. Anything that has the potential to go wrong will, as Murphy’s Law predicts. After shutting off their water heater entirely for many days, we’ve had multiple calls from customers who are unable to get their water heater to switch back on. Particularly vulnerable to difficulties are homeowners who live in older homes or apartments. This is due to the fact that when an old unit is turned back on and forced to heat a full tank of cold water, it may experience a greater level of stress than usual. This additional strain may result in the need for repairs.

Instead of turning off your water heater, do this…

If you’re going on vacation, lower the temperature of your water heater or set it to ″vacation″ mode.It is possible to reduce the amount of power and gas that your model will consume while you are away from home by adjusting the thermostat down or setting it to ″holiday″ (a feature available on certain newer models).Almost all contemporary water heater types include this vacation feature, which is typically designated as ″VAC″ on the thermostat.Typically, the ″VAC″ mode will lower the water temperature to 50 degrees Fahrenheit, allowing your water heater to operate at a lower efficiency than it would otherwise (when the water is continually heated at 120-130 degrees Fahrenheit).

However, this setting also maintains the water somewhat warm, which helps to prevent your unit from overworking itself when you switch it back on again.Is this ″VAC″ option not visible to you?Then just reduce the output temperature on your water heater thermostat to anywhere between 50 and 70 degrees Fahrenheit.

This will provide the same consequences as using the vacation mode on your computer.

Other ways to lower your water heating costs

  • Are you looking for more strategies to cut your power bills? Then take into consideration the following water heater energy-saving recommendations: Insulating your tank might result in annual savings of 7 percent to 16 percent. Your water heater is likely to be warm to the touch, which indicates that you are losing money right now. Due to what is known as ″standby heat loss,″ older water heaters lose a significant amount of their heat via the tank itself (which is why the water feels heated). In order to reduce your standby heat loss, get your tank professionally insulated.
  • Make sure to get your unit cleansed and serviced on a regular basis. A water heater in Arizona should be cleansed at least once a year, according to the manufacturer. Water heater flushing is the process of totally emptying it, cleaning out any sediment buildup, and then refilling it with water. Because we have ″hard″ water in Arizona, sediment building is a common occurrence here (water with a lot of minerals in it). These minerals gradually sink to the bottom of your water heater and act as an insulator between the burners and the water, causing your water heater to work harder and for a longer period of time than it should.
  • Reduce the output temperature to save 4 percent to 22 percent per year on energy costs. By lowering the temperature of your water heater, you may reduce the amount of gas or energy that your device requires to keep the water hot. Take note that temperatures below 120F can raise the danger of Legionnaires Disease
  • thus, do not go below this degree.

Installing and maintaining your water heater by a genuine specialist is always the best alternative, as water heaters that are not properly installed and maintained nearly never fail.They are educated on what may and does go wrong with them, as well as how to avoid it in the first place.When water heaters are not properly maintained or installed, they can pose a serious threat.

Observe the following indicators that your water heater may be about to blow up:

Signs That Your Electric Water Heater May Explode

  • Popping, pounding, or banging noises – Does it sound like popcorn is coming out of the heater’s combustion chamber? Over time, particles can accumulate in your water heater, causing obstructions that prevent warm water from rising to the top. It is the water bubbling beneath the accumulation that is making the popping sounds when it exits.
  • Gas leaks are frequently indicated by a sulfurous or rotten egg smell, which should be treated as a life-threatening emergency. If you are able to, switch off the gas and contact a professional as soon as possible. However, if you moved from gas to electricity and discovered that the original gas line had not been properly sealed, it is possible that the problem was caused by the original gas line being improperly capped.
  • It is usually found at the top of the heater and is responsible for releasing pressure as well as water from the tank when the heater leaks. If this valve is leaking, it signals that the pressure within the water tank has risen to an unsafe level, and it may even explode if the pressure continues to rise. If you observe this, you should immediately switch off your water heater.
  • Thermostat connections that are incorrectly connected — An improperly installed water heater is subject to a variety of concerns, including the possibility of an explosion, therefore it’s always best to have a competent specialist install and maintain your water heater.

  • It is possible to take steps to guarantee the proper maintenance of your water heater, which will ultimately improve the overall safety of your property. If you are familiar with the normal functioning parameters of your water heater, you can check on the temperature and pressure valve to see if anything is wrong with it at any time.
  • Reduce the water temperature – It should be set between 120 and 130 degrees Fahrenheit, with typical recommendations of 125 degrees Fahrenheit. Scalding, scorching, or wounded skin, as well as catastrophic damage to your water heater and sewage system, are all possible consequences of exceeding this limit.
  • Make an appointment for a yearly tune-up – Keeping on top of your water heater’s maintenance should always entail having a licensed and dependable professional take care of the job for you. Your expert will be able to cleanse your water heater at the same time that they are checking for problems, which will improve the taste of your water as well as the efficiency of your unit.
  • Allow experts to do the task – As tempting as it may be to complete the work ourselves in order to save money, doing so may result in sloppy or unskilled work. A water heater that has not been properly installed or serviced is more likely to explode. When it comes to repairs, it is usually better to leave them to the pros.
