How To Replace Water Heater Anode

How to Replace an Anode Rod (6 Steps)

Please keep in mind that this content may contain affiliate links. This means that, at no additional cost to you, we may gain a small profit on purchases made via our links. The anode rod replacement instructions offered here are generalized to work with a broad variety of brands and heater designs, and you may need to change some of the procedures to make them work with your specific model. For example, the anode rod on some General Electric models is concealed under a plastic cap that must be removed in order to gain access to the component in question.

Because it does not sacrifice itself in the same way as a regular anode, it requires no maintenance.

Step 1 – Shut Off the Power and Water

Always switch off the circuit breaker or turn off the thermostat on gas-powered water heaters before doing any work on the unit. If your gas water heater has a “Vacation” option, you may use it to do maintenance on the device without having to relight the pilot afterwards. To turn off the cold water supply line, first check to see whether there is a valve on the line; otherwise, turn off the water at the meter or at the pump.

Step 2 – Locate the Anode Rod

The anode rod will be situated on the unit’s top side, as shown in the illustration. In other instances, it may be directly linked to the hot water outlet pipe located on the top of the heater itself. It is possible that your water heater’s user handbook contains a schematic that illustrates where the anode rod is placed; alternatively, you may visit the manufacturer’s website for further information.

Step 3 – Drain Some Water Out of the Tank

Using a garden hose, connect the drain exit on the bottom of the heater to the outside of the house. Hose should be extended to an outside location or to a plumbing drain that is lower than the tank’s water level. Only around ten percent of the water should be drained from the tank. If you have an anode rod that is positioned on the side of the tank, you will need to empty more. The extra weight in the tank will keep the entire water heater from turning while you attempt to loosen the rod, which is important because many old rods are difficult to remove.

The water will not drain from the tank unless both the drain valve and the hot water valve are opened simultaneously.

Tip: While you’re at it, you might as well totally flush and clean the water heater because half of the job is already done.

Step 4 – Remove the Anode Rod

The anode rod can be removed by using a boxed end wrench or a socket with a square drive. If a wrench is unable to turn the part, a socket and breaker bar should be used.

Small adjustments to the anode rod’s tension will aid in breaking the threads loose, making removal easier. Never use penetrating fluids on water heater components, such as Liquid Wrench, since these fluids have the potential to pollute your hot water supply.

  • Because twisting the water heater might result in leaks or broken pipes, it is recommended that you have a buddy hold the tank while removing and inserting the anode rod
  • It is possible that you may have to cut a pipe in order to replace the anode rod in some cases. Depending on your available space, it may be required to bend the rod in order to get it out. Never knock on the components of a water heater, since the tank liner is readily damaged in this manner. If the anode rod has been corroded with silt and is too big to pull out of the tank, it indicates that the component is still in good working order and should be replaced. In this case, it is necessary to replace the present anode rod.

Step 5 – Install the New Anode Rod

A flexible anode rod may be required if there is insufficient space in your installation. Ensure that the threads on the new anode rod are facing downward and that they are wrapped with plumber’s tape or gently covered with joint compound. Insert the new rod, or the old rod if the old one is not being replaced, into the hole. Turn the component clockwise until it can no longer be twisted by hand, and then tighten it another 1/2 turn with your socket wrench to ensure it is completely secure. Allowing the water heater to spin or twist while doing so is not recommended.

Aluminum vs Magnesium Rods

Anode rods are available in two materials: aluminum and magnesium. Almost many expert plumbers will tell you that a magnesium anode rod is preferable than an aluminum anode rod simply because it creates a greater current than aluminum anodes do. Tank corrosion may be combated more effectively as a result of this improvement in performance. However, the most significant disadvantage of magnesium rods is that it may react with bacteria in the water, resulting in the production of a faint sulfur smell, which is not an issue with aluminum.

A powered anode rod, in my opinion, is the greatest option, although the cost can be significantly more than that of a standard sacrificial anode.

Step 6 – Restore Water and Power

Check to see that the drain is completely closed, and then switch on the cold water supply. Pour hot water into the tank using the same hot water valve you used to drain it, allowing it to flow until all air has been evacuated from the tank. Pitching or hissing sounds will be produced by the faucet as air escapes through the pipe on an irregular basis.

  • Examine for leaks and make any required modifications if necessary
  • Return electricity to the water heater or adjust the gas thermostat to the appropriate water temperature.

How to Change a Water Heater Anode Rod

This Old Houseplumbing and heating professional Richard Trethewey demonstrates how to replace the anode rod on a water heater in this instructional video. Steps: Water heater should be turned off, as well as the fuel source (gas or electricity). 2 Drain the water heater to a certain extent. Find the anode rod on the water heater and, if required, remove and take it off of its mounting bracket at the top of the water heater. 4 To remove the anode rod from the heater, use a ratchet wrench and a 1 1/16-inch deep socket to unscrew it.

6 Remove and remove the old anode rod from the circuit.

8 If there is insufficient room above the heater to accommodate a normal anode rod, a collapsible anode rod should be used.

Shopping list:

  • Anode rod
  • Steel pipe that is used to offer additional leverage to a ratchet wrench
  • Anode rod and steel pipe Teflon tape
  • A garden hose, which was used to empty the water heater partially

Mr.

Fix-It-Up-For-The-Family Replacing the anode rod in a water heater before it breaks may considerably increase the life of the water heater, sometimes even doubling it, by slowing down corrosion inside the tank and increasing the temperature of the water.

Remove the old anode rod

Short bursts from your impact wrench are all that is needed to loosen the hex head. Once it’s free, you may unscrew it by hand.

Photo 2: Install the new water heater anode rod

Pipe dope should be applied to the threads before inserting the new rod into the tank. Tighten with a socket and ratchet by hand to get the desired tension. The majority of water heater tanks are made of steel with a thin layer of glass on the inside to prevent corrosion. Because the lining ultimately fractures, tanks have a second line of defense against rust: a long metal rod known as a “anode rod,” which attracts corrosive substances in the water and draws them into the tank. When the rod itself becomes so corroded that it is no longer able to perform its function, the tank rusts out, leaks, and eventually needs to be replaced.

  1. Magnesium, aluminum, and aluminum/zinc alloy are the materials used to make rods.
  2. The hexagonal head of the rod is visible on the top of the water heater in the majority of instances.
  3. The rod may be hidden behind the sheet metal top of the water heater or it may be linked to the hot water outflow nipple.
  4. Drain several litres of water from the tank by opening the drain valve located towards the bottom of the tank.
  5. Drain a small amount of water from the tank to inspect for rusted parts.
  6. If the water is clear, you can remove the rod and inspect it for damage.
  7. If you don’t already have an impact wrench, you can get one up for approximately $30 on Amazon.

Turn off the electricity or gas.

Use the impact wrench to loosen the hex head, but unscrew the rest of the way by hand to complete the job.

Remove it from its hiding place and lift it up and out to inspect it (Photo 1).

If you have fewer than 44 inches of clearance above your heater, a flexible rod should be installed (Photo 2).

Every three years, you should inspect the condition of your anode rod.

Using any sort of wrench will suffice if it protrudes above the surface.

Spray the head with a lubricant such as WD-40 and allow it to soak in for a few minutes to allow it to penetrate.

It is common for the weight of the water in the tank to prevent the entire heater from spinning.

Immediately stop rotating and inspect the area surrounding the hex head for signs of water.

You may need to bend the rod when you remove it from the tank if you do not have enough overhead clearance.

Before you install the replacement rod, apply a thin layer of Teflon pipe thread sealant to the threads of the rod.

It is not recommended to use tape since it might diminish the efficiency of the rod. Drain another gallon from the tank before turning on the water, electricity, or gas to ensure that all debris has been flushed from the system.

Tips for buying an anode rod

Anode rods are intended to attract corrosive elements in the water, so reducing corrosion in the steel liner, which is particularly prone to corrosion.

  • Anode rods made of magnesium are more effective at protecting your tank, but they do not last as long as rods made of aluminum or zinc. Anode rods made of aluminum or zinc are less expensive and are advised if your water smells. However, before making the conversion to an aluminum rod, contact with a water treatment professional.

How to Change a Water Heater Anode Rod – PlumbingSupply.com

Many individuals are not aware of how important the anode rod is in protecting the liner of their water heater’s tank, and how much it costs. An “Anode Rod,” which is a long metal rod made of a variety of metals, is found within every water heater. This rod shields the tank from corrosion by corroding first, prior to the tank, and so preventing corrosion. The tank begins to corrode as soon as the anode is depleted. This extremely crucial component of your water heater may need to be updated from time to time in order to keep it from corroding.

  • Are you unsure about where to begin?
  • Please keep in mind that there are various different manufacturers of water heaters, each of which may require a separate set of instructions or supplementary information.
  • Prior to undertaking this procedure, we strongly recommend that you contact the manufacturer of your water heater with any questions you may have.
  • Items and tools required include:
  • Wrenches with a closed end or a 1-1/16″ socket wrench, as well as a ratchet or breaker bar
  • Pipe wrench (for use exclusively with hot water outlet anode rods)
  • Garden hose of the most basic type
  • Thread sealing tape made of PTFE or high-quality thread sealing compound

Step 1: Identify and locate the anode rod. The anode will be situated on top of the water heater in the majority of cases, while some may be located on the side. The majority of the time, it will look like a hexagonal plug that has been screwed into the heater. Some heaters have the anode linked to the hot water output port and seem to be a pipe nipple; to view an example of what this looks like, please check the following link. This sort of anode is covered in further detail in the section titled “Hot Water Outlet Anodes” below.

  • Turn off the circuit breaker that serves the heater if it is an electric heater.
  • Turn the gas control valve to the lowest setting, or the “vacation” setting, if you’re using an agasheater.
  • The next step is to turn off the COLD water supply to the water heater.
  • After that, direct the hose to a drain or outside the home to discharge the water.
  • Draining the water may cause it to become quite hot, so use caution when touching the hose.
  • Keep in mind that if your anode rod is located on top of the heater, you will only need to let the tank to drain around one quart or half a gallon of water before continuing.
  • After that, close the outlet and disconnect the hose.

Afterwards, drain the water into a big container, which may then be used to water a plant when it has been allowed to cool down.

This lowers the pressure in the tank by allowing air to enter the tank, which breaks the vacuum and allows the water heater to drain more easily and efficiently.

Step 6: Make use of a closed end wrench or a 1-1/16-inch hex key “For removal of the anode, use a socket wrench and a ratchet or breaker bar on the hex head.

Try using a “breaking bar” to provide more leverage, or tightening the rod just a little bit further to loosen up the threads if that doesn’t work.

The anode should not be beaten with a hammer since the tank has a glass liner that might be destroyed, which would enable corrosion to begin.

Step 7: Once the anode is free of the heater, carefully remove it out of the heater.

Since the anode is meant to corrode within the tank, there is usually not much left of it by the time it needs to be replaced.

The anode can be screwed back into the heater and replaced at a later time in this situation.

A total of five or six wraps around the threads are required.

Step 9: Insert the new anode rod into the circuit.

If you have a limited amount of room, you might want to consider utilizing a flexible anode.

Protect the heater firmly in place by having someone else hold onto it to keep it from shifting and maybe causing damage to the pipe connections.

The hot position should be maintained on the faucet we indicated before.

Wait until all of the air has been evacuated from the tank before allowing the water to flow from the faucet.

When the water is flowing freely, any air in the tank should be expelled. Step 13: Inspect the heater’s connections for any leaks that may have occurred. Step 14: Turn on the electricity if it is being used. In the case of gas, return the control to its original temperature setting.

Hot Water Outlet Anodes

It is possible that certain water heaters have what is known as a “Hot Water Output Anode” placed in the outlet side of the water heater. In most cases, they will need to be changed at the same time as the ordinary anode rods in the battery. Due to the fact that they will be linked to the incoming plumbing, the removal and installation procedures will change. The majority of the time, a flexible connection will be made between the hard plumbing and the anode’s nipple. It is sufficient to loosen the nut of the flex line that is attached to the nipple in this scenario.

Occasionally, instead of using a flex line, the hard plumbing may be linked directly to the anode’s nipple in a very specific situation.

After that, the pipe would have to be replaced.

3 Types of Water Heater Anode Rod Issues & Steps to Fix

It is common to ignore the many components and sections of a water heater. However, it is critical to be knowledgeable with the components of your water heater in order to be able to respond promptly when issues arise. The anode rod is one of the most vital components of a water heater, and it is one of the most expensive. The purpose of an anode rod has been outlined in order to assist you in diagnosing problems with your water heater. Additionally, we have developed a list of three different sorts of anode rod concerns, as well as the actions you will need to do in order to replace a deteriorating rod.

What Is An Anode Rod and How Does It Work?

An anode rod is a steel wire that is surrounded with a layer of zinc, aluminum, or magnesium to provide corrosion resistance. In most cases, it’s roughly 4 feet in length. It is fastened into the top of a water heater and serves to prevent rust from forming in the water tank. This is accomplished by the use of an electrolysis technique. The anode rod is intended to be immersed in water in order to draw rust and other impurities to the electrode.

Because this component draws pollutants in the water, it will help to prevent and slow down the degradation of the inner steel walls of the water storage tank. This self-sacrificial action of the metal rod protects the longevity of the water heater since it prevents rust from forming.

Ordinary Problems With Anode RodsTips

Anode rods are expected to last between three and five years, however the length of time they endure is highly dependent on the quality of your water and how much water passes through the water heater. Different factors might contribute to their inability to work properly. Three sorts of difficulties can develop with anode rods, as listed below.

Deterioration

The most typical sort of issue that arises with an anode rod in a hot water heater is degradation of the rod. In contrast, deterioration and corrosion of the rod indicate that it is performing its function, which is why this is the most frequently seen problem. If the steel wire that makes up the rod’s core is visible, it may be time to replace the rod altogether. Anode rod corrosion begins at the top or bottom of the rod and progresses down to the core of the rod over time. If the degeneration is greater than 6 inches in length, it is time to replace it with a new one.

Soft Water With High Mineral Concentration

Water softener systems add softening chemicals to water, such as phosphates and rock salt, to make it more drinkable. Despite the fact that soft water may be favored by some, it can actually cause the anode rod in the water heater to corrode three times as quickly as hard water. It can even corrode the steel wire core of the tank, which can result in damage to the tank’s hex head as well as the tank’s internal structure. If the anode rod has shrunk to more than 120% of its original diameter, it is necessary to replace it.

Collection of Calcium Carbonate

A calcium carbonate deposit on the outside of an anode rod in a water heater is not out of the ordinary in this situation. The presence of these white minerals prevents the rod from corroding. While this may be advantageous in other circumstances, the anode rod’s primary function is to corrode in order to keep the water tank safe. You may easily remove the calcium carbonate by wiping it away with a cloth.

How To Replace A Deteriorated Anode Rod

Before you do anything, you must turn off the electricity and water. If you have a gas-powered water heater, you may switch off the circuit breaker or the thermostat to save energy. Using the valve on the cold water supply line, turn off the water to the house. You can also turn off the water supply at the meter itself. Water meters are normally positioned outside your home and have a gray or brown cover on top of them to identify them.

2.) Locate the Anode Rod

As previously stated, the anode rod for your water heater is located at the top of your water heater. If you are having difficulties locating it, consult the owner’s handbook for your water heater to find out where it is. Alternatively, you may search up the model number of your water heater on the internet and view a schematic of the appliance.

3.) Drain the Water From the Hot Water Tank

The water heater’s tank has a drain valve located at the bottom of the tank. Connect a garden shed to this outlet and extend it outdoors or near a drain to make it more functional. Fill the tank with water until it holds roughly 10% of its capacity.

Depending on whether your tank’s anode rod is on the side or the bottom, you may need to remove more water. Make sure the drain valve is open, as well as the hot water valve, in order to do this properly. A large number of people choose to drain the entire tank.

4.) Disassemble the Anode Rod

To remove the anode rod from the hot water heater, use a boxed end wrench or a socket with the boxed end. Tightening the anode rod before attempting to release it might aid in breaking it loose and making the removal process more straightforward. Use of penetrating fluids should be avoided since they have the potential to enter your water heater and pollute the water. To determine whether or not your water heater’s anode rod is still in excellent condition, pay close attention to what occurs when you attempt to remove it from the water heater.

If it has entirely rusted away, it will be possible to be removed from the water heater without difficulty.

5.) Purchase and Install the New Rod

Purchase a replacement anode rod from your local hardware shop. Purchasing an aluminum rod rather than a magnesium rod may extend the life of your heater since metal generates a greater current. If you’re installing the rod by hand, insert it and spin it clockwise until it can’t be twisted any further. After that, using a socket wrench, tighten it even further. Make certain that the water heater does not spin or twist when you are performing this procedure.

6.) Activate the Water Heater

Ensure that the drain valve has been closed and that the cold water supply has been turned on if it has not yet. Pour hot water into the tank using the same hot water valve you used to drain it originally, allowing it to flow until all air has been removed from the tank. As air exits via the faucet, it will generate spitting and hissing noises. Set the thermostat to the appropriate water temperature after re-igniting the power or gas supply.

How to Inspect and Replace a Sacrificial Anode Rod (Every 3-5 Years)

A rusted anode rod on your water heater tank might eventually cause the tank to explode since there is no sacrificial metal left on the anode rod anymore. Anode rods typically have a lifespan of three to five years, however this is highly dependent on the quality of your water and the amount of water that passes through your water heater during that time. Every three years, you should inspect the condition of your anode rod in order to lessen the likelihood of a leak, enhance the quality of your water, reduce water heater wear and tear, and save a significant amount of money.

How Do Sacrificial Anode Rods Work?

The sacrificial anode rod is the most critical component of a water heater’s design. It absorbs all of the damage so that your tank and pipes don’t have to deal with it.

Additionally, a healthy anode rod helps to limit the amount of silt that accumulates at the bottom of your tank, which can cause your energy expenses to rise over time. Sacrificial anode rods are available in three different materials:

A more reactive (i.e., least noble) metal is used for the sacrificial rod because water is attracted to steel-lined water tanks and metal pipes in your home. In most cases, the steel water tank will be totally destroyed before the sacrificial anode rod corrodes away completely. As long as the anode rods in your water heater tank are examined and changed on a regular basis, your tank will be safe against corrosion.

Top 10 reasons to replace your anode rod

  1. You’d like to extend the life of your water heater as much as possible. It will cost you far less to replace the anode rod than it will to replace your water heater. When the water heater pan starts collecting water, it is considered a problem. Anode rod corrosion can be accelerated by the use of water softeners. Corrosion of anode rods can be hastened by acidic water. When the water heater is heating up, it creates loud or numerous popping noises, which indicates that there is probable corrosion in the tank liner. It’s been three years since you last checked/replaced the anode rod in your vehicle. Aerators on faucets appear to be clogging up more regularly
  2. When you clean the faucet aerator, you notice a slimy gel material on the surface. Water that is gritty, sandy, or has a terrible odour
  3. Water heater expenses that be too high. Old anode rods contribute to the accumulation of dirt at the bottom of the tank, which reduces heat transfer.

How to Replace a Sacrificial Anode Rod

Learn how to replace the anode rod on your water heater in order to keep it from corroding further.

Materials:

  • Drain the water from the bucket or the hose using the appropriate tools. An impact socket with six points and a 1-1/16″ diameter
  • Perhaps a second (or two) pair of hands
  • Replacement anode rod for sacrificial anode

Steps:

You should be able to find the gas line around the bottom of your hot water heater. Gas should be turned off by moving the valve clockwise; the valve should be perpendicular to the pipe. If you have an electric water heater, locate the breaker that corresponds to it in the main service panel and turn that breaker off. After you’ve turned off the gas or electricity, turn off the cold water supply, which is often located on the right side of the unit at the very top. A ball valve (with a handle that runs parallel or perpendicular to the pipe) or a gate valve can be installed in the cold water supply line (handle that you have to spin).

  1. Drain a couple of liters of water from the tank, which is approximately 10% of its total content.
  2. To drain the boiler, connect a garden hose to the “boiler drain,” which is situated on the bottom part of the tank.
  3. Remember not to drain too much water since the weight of a fully full tank will assist you in detaching the anode rod from the tank’s anode.
  4. It is possible that you may have to remove the complete top lid in order to locate it.
  5. Look for the hex head on the unit’s top, which should be visible.
  6. Compared to other socket sizes, this one is rather huge.
  7. Opt for the heavy-duty model!

It is not easy to remove an anode rod from a circuit.

The weight of the water in the tank should aid in the process; nevertheless, you may want the assistance of another person to hold the water heater while you remove the hex head.

It is not recommended to twist the water heater, since this might cause damage to pipes and fittings.

You may utilize a tiny metal pipe segment that fits over the impact socket to expand the length of the impact socket and increase the amount of leverage available.

In this instance, seek the advice of a specialist.

Depending on your ceiling height and available space, you may have to bend the anode rod to get it out of the way.

Wrap the joint threads of the new anode rod with Teflon® tape (plumber’s tape) to prevent corrosion.

Once you’ve gotten the anode rod in there, tighten it by hand until you can no longer do so.

It is not necessary to tighten the water heater so tightly that it begins to move or twist.

How To Replace an Anode Rod

Previous PostNext PostWhen was the last time you had your water heater’s anode serviced or replaced? Are you unfamiliar with the term “water heater anode”? You’ve come to the correct place! The specialists at Aire Serv will teach you all you need to know about water heater anode replacement in the next section of the article.

What Is an Anode Rod?

An anode rod for a water heater is a steel rod that has been coated with a second type of metal, which is often zinc, aluminum, or magnesium. The rod, which is fastened into the top of the tank, is responsible for reducing corrosion within the tank’s interior. In order for a water heater to work properly, the anode, also known as a sacrificial anode, must be present. This is because the anode protects the water-soaked walls of the tank from corrosion. The rod acts as a decoy for corrosive substances, causing corrosion to occur on the rod rather than on the tank’s interior surface.

How Often Should You Replace a Hot Water Heater Anode?

Water heater anode rod replacement intervals can range from six months to six years in the most extreme conditions, depending on the nature of the water you are using. A water softener or unusually hard water might cause your anode to degrade more quickly than normal. Our recommendation is that homeowners plan on changing their water heater anode every two to four years as a general rule of thumb. When a new homeowner takes ownership of their house, they should enquire as to when the water heater was last professionally serviced.

How to Remove a Water Heater Anode Rod

The replacement of the anode in a water heater can be done by the homeowner. If you want to examine or replace the anode in your water heater, you should follow these steps:

  • In the case of electric water heaters: Turn off the water heater and turn off the electricity to the unit at the main circuit breaker.
  • If you have a gas water heater, turn it into “vacation mode” so that you don’t have to worry about re-igniting the pilot light.
  • Immediately turn off the water supply
  • Drain the water heater with the help of the water heater drain, a short hose, and a bucket for general use
  • Using a socket wrench, remove the anode rod from the top of the water heater tank and set it aside. Remove the anode rod from the tank with care by raising it straight up from the tank. Take care not to hit the anode on the tank or cause it to ring or rattle. This has the potential to break the rod or cause harm to the tank’s inside. Examine the anode rod for damage. Reinstall the rod if it still appears to be in good condition. If it has been extensively corroded, has been decreased in size, or has been somehow damaged, it should be replaced. Install the new water heater anode rod into the tank’s top by screwing it in place. The water supply and electrical connections to the tank should be reconnected.

How to Remove a Stubborn Anode Rod

How To Replace The Sacrificial Anode Inside Your Hot Water Heater

By changing the sacrificial anode in your hot water heater, you may extend the life of the appliance. The sacrificial anode’s goal is to corrode in place of your hot water heater’s internal components. The majority of the components in your house are not intended to degrade over time, but that is exactly what the sacrificial anode is intended to accomplish. The good news is that changing the sacrificial anode is a straightforward task that can be completed by the ordinary do-it-yourselfer. The approach outlined below will guide you through the process of removing the old component and installing a new anode.

  1. Turn off the hot water heater if necessary.
  2. Never attempt to work on a water heater that is currently in use; otherwise, you may end up with a terrible burn on your hand.
  3. You must first turn off the burner and pilot light on your natural gas hot water heater at the thermostat, after which you must switch the shut-off valve on your natural gas supply line to the “off” position.
  4. Typically, the cold water supply valve will be painted blue in order to distinguish it from the hot water output valve.
  5. Unplug the Hot Water Heater and let it cool.
  6. As an extra bonus, this step will remove any sediment that has accumulated at the bottom of the tank throughout the cleaning process.
  7. All that is required is that you hand-tighten the connection.

Make sure the hose is directed to a safe location, such as a storm drain or a five-gallon pail, at the other end.

3.

The sacrificial anode should be removed when the hot water heater has been completely emptied.

Locate a socket that matches the sacrificial anode’s size and use a ratchet to remove it from the hot water heater.

Continue to unscrew and remove the anode out of the hot water heater until it is completely free.

4.

After you have removed the old sacrificial anode, check the water heater threads to make sure they are generally clean before replacing them with new ones.

After that, use PTFE tape to seal the threads of the new anode to ensure that it is completely waterproof.

After you have hand-tightened the anode, you may use your socket and ratchet to further tighten the connection.

Restore service to the hot water heater if it has been interrupted.

Turn off the drain valve, disconnect the garden hose, and then turn on the cold water supply valve located at the top of the hot water heater to fill the tank with cold water.

After a few minutes, you may start the hot water heater by turning on the electrical or gas supply lines.

The next step is to switch on the hot water heater itself by turning the thermostat to the appropriate setting. Contact Moody Plumbing Inc. if you have any queries regarding hot water heaters or need assistance. They are here to assist you with any plumbing need you may have. ​
