What Does It Mean When Hot Water Heater Leaks?

What Does It Mean When a Hot Water Tank Starts Leaking?

  1. It is not always the case that a leaky hot water heater indicates that the tank has to be replaced.
  2. Some leaks appear to be coming from the tank, but they might be coming from somewhere else.
  3. Those other leaks are frequently less difficult to patch and less expensive to replace than the complete appliance.
  4. Investigate the source of the leak in a systematic manner to establish the sort of repair that is required.


  1. It is possible for pipes to drip slowly, resulting in water pooling at or near the bottom of the tank or along the sides of the tank.
  2. Typically, the source is a shaky connection of some sort.
  3. Unfitting joints are easily identified by the presence of water shooting from the fitting.
  4. Turn off the cold water supply and make any necessary repairs to the connection.
  5. The majority of leaks around fittings are more modest in nature.

You should inspect all of the joints, probing them with your fingertips to determine whether they are leaking at all.Plumber’s tape can be used to tighten loose fittings or to repair them by covering the threads with the tape.


  1. Gaskets surrounding the heating elements of electric water heaters that are worn, cracked, or pinched may also cause leaking leaks to occur.
  2. Because the components are buried under a cover plate and insulation, it may be difficult to detect a leak in this location.
  3. Turn off the electrical supply to the hot water heater and remove the insulation by opening the cover plates and pushing it aside.
  4. Check for leaks all around the gaskets with a flashlight.
  5. To replace the gaskets, you will need to drain the tank and remove the components from the tank.


  1. The pressure relief valve, which is located either on top of or on the side of the water heater, is meant to open when the water pressure inside the tank becomes excessive.
  2. It may be found on either side of the water heater.
  3. As steam exits, it condenses, or water drops from the valve onto the floor, depending on the situation.
  4. When the water temperature is set too high, the pressure in the system increases.
  5. On electric versions, you can control this using the thermostat that is linked to the element, and on gas models, you can modify it using the temperature adjustment knob.

A defective relief valve might possibly be the source of the problem.Plumbing specialists should be called in to replace relief valves.


  1. Condensation can accumulate on the sides of the tank and generate puddles on the floor, giving the appearance of a leaky tank in some cases.
  2. When there is a strong demand for hot water, the volume of cold water stored in the tank might considerably outweigh the amount of warm water the heater is attempting to create.
  3. Condensation is the outcome of this process.
  4. If a leak appears only when the tank is being filled with cooler water, condensation may be the source of the problem.


Hot water heater tanks ultimately deteriorate to the point that they leak water from the inside. If all of the lines, valves, and gaskets appear to be in excellent working order, and if condensation does not appear to be a problem, the tank itself is most likely leaking. When this occurs, the only remedy available is to replace the tank.

Leaking from the Bottom of the Tank: Finding the Source

  1. Check the drain valve and the temperature and pressure relief valve if it looks that you have a leak from the bottom of your water heater first, since these are the first things to look for (T&P valve).
  2. It is possible that the leak is located at the top of the water heater and that it is just flowing down through the heater’s body before exiting at a lower elevation.
  3. Take note of any apparent symptoms of a leak on the top of the water heater and along the length of the pipes coming to and from the heater.
  4. You may also check for moisture in the insulation by removing the access panels (if the model is powered by electricity).

Common Causes of Water Heater Leaking from the Bottom

Leaking Drain Valve

  1. All water heaters are equipped with a drain located towards the bottom of the device, which allows the tank to be drained prior to removal or during normal cleaning of the tank itself.
  2. A leaky drain valve can be discovered by the presence of dampness or water pouring from the drain hole or from the area around the valve.
  3. Turn the valve control counterclockwise to ensure that the bottom valve is entirely closed.
  4. If necessary, replace the bottom valve.
  5. If this does not resolve the issue, it is possible that the valve may need to be replaced.

An ordinary water line must be connected between the drain outlet and another location outdoors in order to replace the valve properly.Turn off the water supply to the tank, which is often placed at the top of a water heater’s cold water line near the top of the tank.Drain the tank by opening the drain valve and allowing it to empty.Replacement valves for hot water heaters are readily available at most hardware stores and may be easily installed with a simple socket wrench.

  • To remove the existing valve, turn it counter-clockwise from its position.
  • Plumber’s (Teflon) tape or joint compound should be used to seal the threads of the replacement drain valve before screwing it into the aperture until it is hand tight.
  • Then, using a wrench, spin the drain valve 1/2 turn more, or until the drain is securely in position on the pipe.

Leaking Pressure Relief Valve

  1. The pressure relief valve (also known as the T&P valve) on your water heater is an important safety feature that allows you to release excess pressure if your water heater becomes too hot.
  2. The pressure relief valve is often located on the top of the water heater, however most systems have a tube linked to the valve in order to convey the water to the floor.
  3. Due to the fact that the overflow tube discards the ejected water beneath it, it may look as though there is a problem at the bottom of the tank when the T&P valve is leaking.
  4. The first step is to check the thermostat setting to ensure that it is not set too high, as the T&P valve is designed to enable water to be discharged from the tank when it is opened.
  5. If the temperature is normal, it is probable that the pressure relief valve will need to be replaced.

Leaking Tank

  1. Water heaters that are not cleaned out on a regular basis might develop silt buildup in the tank.
  2. The presence of salt and other chemicals in the sediment may induce early rusting or corrosion within a water heater, which may eventually result in the formation of pinhole leaks.
  3. Once a pinhole leak is discovered, the pressure of the water inside the tank making its way through the opening will cause the leak to grow in size over time as the water inside the tank continues to force its way through.
  4. A leak in an inside closet has been reported in the past, resulting in a consistent supply of water under the crawl space.
  5. The next thing the homeowner knew, he or she was attempting to exterminate a family of chipmunks that had taken up residence under their house.

In this situation, replacing the tank with a new one is the most cost-effective approach.A leaky tank is an evident symptom that a water heater needs to be replaced and should be addressed immediately.It’s usually recommended that you have a professional replace your water heater; but, if you’re a DIYer, you may complete the task yourself.It is necessary on most models to remove all plumbing that is linked to the water heater, as well as to turn off the electricity within the access panel.

  • If you have a gas water heater, make sure to cut off the gas line leading to the water heater and disconnect the line where it enters the tank before turning on the water heater.
  • Replace the old water heater with a new one and link the pipes and electrical supply to the new one.
  • ″How long do water heaters last?″ is a topic that is frequently asked in relation to the tank of the water heater.
  • When the tank is damaged, it is necessary to replace the unit.


  1. In some cases, condensation on the water tank of the water heater will be present.
  2. Older water heaters are more likely to experience this problem, but it can also occur in modern tanks if the insulation has been broken or the thermostat has been set too high for safe operation.
  3. Allow the tank to lie idle for many hours while the electricity and gas are shut off to conserve energy.
  4. Having the leak cease indicates that you are experiencing condensate in your home.
  5. Reduce the temperature on the thermostat and turn on the electricity to the device.

If the problem persists, you may need to replace the tank with a more well insulated type to resolve it.To show exactly how well-insulated modern models have grown, look no farther than our list of suggested water heaters.Additionally, condensation may develop momentarily after a new water heater is installed and the cold water that enters the tank has not had a time to warm up.Condensation is frequently caused by a temperature differential between the inside of the tank and the outer air outside the tank.

Water Heater Burst: Why This Happens And What To Do Next

  1. An unexpected water heater rupture in a house may be a surprising and nasty occurrence, and it has the potential to inflict significant damage that is costly to repair.
  2. Having a hot water heater break leaves you scratching your head, wondering why it happened and what to do next.
  3. In general, the most common reason for hot water heaters to burst is corrosion within the tank, which can result in the tank literally bursting at the seams.
  4. Unfortunately, there are a variety of underlying factors that can lead to water heater explosions, and it is not always clear which one is to blame for the incident.
  5. Sometimes there are risk factors or warning signals that suggest that a water heater explosion is impending, but this is not the case all the time.

The sort of water heater that you have in your house is critical to understanding the risk factors that might lead to an explosion.To do this, first determine what type of water heater you have in your home.

Types Of Water Heaters

Conventional storage water heaters are the most common and popular type of water heater that most people install in their homes; tankless water heaters, which are also popular and can be a good choice depending on various criteria within a particular home, are the other main type of water heater to consider.

Conventional Water Heaters

  1. Storage (or traditional) water heaters feature a tank that retains a certain amount of hot water, which is heated by electricity, natural gas, or oil, depending on the residence and system.
  2. As soon as you turn on a faucet in a house equipped with a storage water heater, the tank’s top begins to fill with hot water, which is then routed via the house’s plumbing to your sink, shower, or bath.
  3. The tank is then supplied with cold water, ensuring that the tank is constantly fully topped off.

Tankless Water Heaters

  1. Because they do not work with a tank of water that must be continually heated and replaced, tankless water heaters save energy by heating water directly on demand whenever a hot water faucet in the home is activated, as indicated by their name.
  2. While traveling from the faucet to the tankless water heater, cold water passes through either an electric or a gas heating element within the tankless water heater, emerging hot and ready to use.
  3. Due to the fact that tankless water heaters do not store hot water, they do not have the same risk of exploding as storage water heaters.
  4. Tankless water heaters have exploded and caught fire in certain cases after being fitted with faulty pressure switches, according to the manufacturer.
  5. Water heaters that are stored in a tank are the most common type to burst, therefore if the water heater in your home has exploded, it’s most probable that it was a typical water heater that caused the explosion.

Water Heater Explosion Warning Signs

  • The fact that storage water heaters are composed of metal and can hold enormous volumes of hot water increases the risk of leaking or even exploding as they begin to rust at the fittings and seams over time increases the likelihood of a leak or explosion. Water can get overheated if the thermostat controlling the temperature of the water within the tank is broken, or if mineral buildup inside the water heater prevents the thermostat from accurately monitoring the temperature of the water within the tank. Because of this, the capacity of the tank will increase and the tank’s fittings and seams will be pressed together. A leak or even an explosion might ensue from the pressure building up around these connections and seams if they are rusty or corroded. Listed below are some of the risk factors and warning indicators that indicate an increased likelihood of a water heater leak or explosion: Your water heater has been in service for more than ten years.
  • When your water heater is heating up, it generates clanking, banging, or rumbling noises, which indicates that sediment has accumulated and hardened inside the tank.
  • Rust is apparent on the outside of the water heater, particularly at the pipe connections and seams that run down the tank
  • and
  • Rusty water emanating from your water heater indicates that there may be corrosion developing up within the unit
  • This indicates that either there is a break somewhere in the tank or that your temperature-and-pressure (T&P) relief valve is not operating properly.
  1. It’s important to remember that water heater leaks aren’t always dangerous, and they don’t necessarily indicate that the tank is about to burst or that the heater needs to be repaired or replaced.
  2. If there is a leak in the water supply pipes that lead into the top of the water heater, for example, this is an issue that is reasonably easy to correct and is unlikely to be a contributing factor to the water heater exploding.
  3. Another cause of water heater leaks that is similarly easy and repairable is a leak at the water heater nipples; these are placed at the top of the water heater, where they link the water pipes to the heater itself, and they are easily accessible.
  4. If the T&P valve is leaking, it may signal that it needs to be replaced or that there is a wider problem.
  5. It’s not possible to repair a leaky water tank, and the tank will need to be replaced entirely if the tank itself is leaking.

What To Do When Water Heater Leaks

  1. In the event that you notice water dripping or seeping out of your water heater, or if you notice water accumulating around it, this indicates that your water heater is leaking.
  2. If you discover a leak, it may be better to consult with a plumbing specialist who can assess the problem and recommend the best course of action for dealing with it.
  3. If you decide to take on the task on your own, there are a few things you should consider.

Turn Off The Cold Water Supply

  1. The cold water supply to the tank should be turned off by shutting the valve placed on the cold water line that feeds into the top of the storage tank.
  2. When you want to turn off this or any other water cutoff valve in your house, turn it clockwise, just as you would when you want to turn off the water at a standard faucet.
  3. The cold-water shutdown valve on your water heater should be turned 90 degrees from its open position in order to shut it off.
  4. Alternatively, if there isn’t a water shutoff valve accessible, you’ll have to turn off the main water supply to your residence.

Turn Off The Power   

After that, go to your home’s electrical breaker box and turn off the electricity to the hot water tank. Without properly shutting down the electricity, the heating elements within the tank may continue to heat up, posing a potential danger to the tank’s contents. The gas line feeding into the tank of your water heater must be cut off as well if you have a gas-powered water heater.

Find The Leak

After that, it’s time to figure out where the leak is coming from. The T&P valve, the drain valve, or one of the lines or fittings that feed into the top of the tank are all possible places for the leak. If you see any rust or corrosion on the outside of your water heater’s tank, pipes, or fittings, it’s possible that they are the source of the leak as well.

Repair The Leak

  1. Following the identification of the cause of your water heater leak, you’ll have a clearer understanding of the procedures you’ll need to take to resolve the issue.
  2. Depending on the situation, it might be a simple remedy (such as tightening fittings with a wrench or replacing the T&P valve), or it could be something more involved.
  3. It is possible that you may need to drain the tank, remove the water heater, and install a new water heater.

What Causes A Hot Water Heater To Leak

  1. When trying to figure out what is causing a hot water heater to leak, you’ll have to select from a variety of choices.
  2. You may have an outdated tank with loose fittings, a loose drain valve, a defective T&P valve, a fractured storage tank owing to corrosion, too high pressure within the tank due to sediment accumulation, or a temperature gauge that is not working properly.
  3. If you don’t have a regular maintenance schedule in place to service your water heater, your hot water heater may begin to leak simply as a result of age and wear-and-tear over time.
  4. Because there are so many different potential causes of water heater leaks, frequent water heater maintenance is extremely necessary as a safety precaution to prevent the danger of an explosion from occurring.

My water heater is leaking from the top

  • It’s probable that if you observe water leaking from the top of your water heater, it’s coming from one of four locations: The cold water intake pipe/valve
  • the TPR valve
  • the anode rod port
  • and the expansion tank are all examples of components.

If the cold water inlet valve is leaking…

  1. You will most likely see water coming from this location: This is the valve that allows cold, incoming water from your home’s main water supply to enter and fill your water heater’s storage tank.
  2. It is possible that the valve itself (which is located higher up on the line) has failed, causing water to leak down into the pipe and onto the top of your water heater.
  3. Water will flow from the point indicated by the red arrow in Figure 1 if a pipe fitting is not properly attached to the pipe.
  4. What to do is as follows: Using a wrench, tighten the pipe fitting if it appears to be loose and you notice water seeping from this spot.
  5. If you see water dripping from the valve, you’ll need to get it replaced by a professional plumber.

If your TPR valve is leaking…

  1. .you will see water coming from this location: The temperature and pressure relief valve (TPR valve) in your water heater tank is a safety feature that only operates when the pressure and temperature within the tank are at an unsafe level.
  2. When the levels in the tank reach an unsafe level, the valve opens and emits hot water to reduce the pressure within the tank.
  3. If you have a typical discharge from your TPR valve, water should be released through the ″discharge pipe″ that runs the length of your water heater.
  4. As a result, if everything is functioning properly, you should only ever see water dropping towards the floor when your TPR valve is activated.
  5. However, occasionally, the valve itself (as seen in the image above) becomes faulty and fails to fully shut, allowing some hot water or steam to escape from this location.

What to do is as follows: If the TPR valve is leaking, it should be replaced by a professional.This is a critical safety feature that prevents your water heater from rupturing as a result of excessive pressure.It is therefore an indicator that the valve will not function correctly when needed if it is found to be leaking.

If water is leaking from your water heater’s anode rod port…

  1. You’ll see water coming from this location…
  2. Your anode rod is a long, slender rod that is installed inside your water heater to prevent corrosion of the tank.
  3. It is made of copper.
  4. Because corrosive substances in your home’s water ″eat away″ at the interior of your water heater over time, you should consider replacing it.
  5. The anode rod, on the other hand, is meant to draw all of those corrosive substances and ″sacrifice″ itself in order to prevent your water heater tank from corroding.

Although it is possible to replace the anode rod after it begins to corrode, this is not recommended since the corrosion will eventually reach the top of the rod, causing water to bubble up and flow out of the anode rod port (seen above).What to do: Have a professional repair your anode rod as soon as possible to prevent the inside of your water heater tank from becoming corroded and rusty.

If the expansion tank is leaking…

  1. Upon closer inspection, you’ll see water pouring from this little tank: Some water heater systems are equipped with a smaller tank referred to as the ″expansion tank.″ This tank is located to the side of your water heater and is intended to collect any extra water that may accumulate in the tank of your water heater.
  2. As you can see, water expands as it is heated.
  3. Additionally, because water expands after being heated, it might often overrun the available area within the tank.
  4. This results in extra water being transferred to the expansion tank, which helps to reduce the pressure levels inside the water heater.
  5. However, with time, your expansion tank may begin to leak as a result of normal wear and tear.

What to do is as follows: The expansion tank should be inspected to establish the location of the leak.If the leak is coming from the pipe fitting (which can be seen at the top of the tank), try tightening the fitting using a wrench.It is necessary to see a professional in order to repair or replace the expansion tank if the leak originates within the expansion tank.

My water heater is leaking from the bottom

In the event that you discover water leaking from the bottom of the water heater tank, it is most likely originating from one of two locations:

  1. TPR discharge pipe
  2. Drain valve

If your TPR discharge pipe is leaking…

  1. .you’ll see water leaking from a long pipe that goes down the length of the water heater and comes to a stop approximately 6 inches above the ground.
  2. So, what does all of this imply?
  3. Basically, it signifies that your water heater’s tank has a dangerously high level of pressure inside it.
  4. When the TPR valve (placed at the top of the water heater) detects excessive pressure levels, it automatically opens to drain the water.
  5. When it opens, the water heater’s discharge line allows water to flow out of the bottom of the tank and into the drain.

In most cases, a hissing noise is produced by a TPR valve that is discharging its contents.What to do: Have your water heater inspected by a professional as soon as possible.They will be able to discover what is generating the excessive pressure levels within the water heater and will be able to correct the problem.

If water is leaking from the drain valve…

  1. If you look closely, you’ll notice water pouring from this device: Using the drain valve on your water heater, a plumber may ″flush″ your water heater and get it back to working order (that is, drain it, clean it and fill it back up).
  2. The drain valve, on the other hand, may get blocked with particles or silt from the water over time.
  3. And when this happens, the valve may not seal correctly, allowing water to spill out.
  4. The best course of action is to have a professional replace the drain valve.

If the water heater tank itself is leaking…

  1. Water heater replacement should be done as soon as possible, so contact a professional right once.
  2. In other words, the fact that there is a leak in the tank itself indicates that the tank is corroding from the inside out.
  3. It’s also only a matter of time before the tank breaks, inflicting possibly extensive water damage to the surrounding area.
  4. What to do: Call a plumber right once to get the water heater fixed as soon as possible.

what to do with a leaking water heater

  1. Water heaters are built to last a long period, but even the greatest ones can develop leaks over time.
  2. A leaky water heater does not always indicate that it has to be replaced, but you should address any leaks as soon as they are discovered.
  3. The presence of even a tiny amount of water can do significant harm, thus it is critical to assess the situation immediately when it occurs.
  4. First and foremost, determine the source of the leak.
  5. Even if a little quantity of water is visible below your water heater, it is possible that the water heater is not the source of the leak.

Remove any standing water and assess the area.Are any of the fittings dripping or are there any other symptoms of leakage that you’re aware of?Make a thorough search of your surroundings for any other potential water sources.Where did you find the water?

  • Was it near a window or another water pipe?
  • Keeping in mind the laws of gravity, if your floor slopes in any way, it’s possible that water went from another spot to where you discovered it.
  • If you are unable to locate the source of the water straight away, place some paper towels where the water was discovered and check again in a few hours to a day or two.
  • When you return, please The presence of damp towels indicates that there is a problem, and the water heater may be the source of the problem.
  • If you’ve discovered that the source of the leak is your water heater, follow the steps below to assess the problem, or just give us a call and one of our highly trained professionals will come out to inspect the situation.

follow these steps to assess the situation

  • Water heater leaks should be addressed immediately by shutting down the water supply to the tank. On the cold inlet pipes of your water heater tank, there should be a specific shutdown valve for your water heater tank. If you have a gate-style valve (a valve with a rotating wheel), spin the valve as far clockwise as you possibly can.
  • If the valve is a ball-style valve, turn the handle 180 degrees
  • otherwise, turn the handle 180 degrees.
  1. Please contact us at (866) 264-9642 if you need assistance working through this.
  2. If the valve in your home is damaged, you can turn off the water supply to your home.
  3. Every home should be equipped with a main water shutoff valve, which would allow the flow of water to be stopped throughout the whole house.
  4. We encourage you to phone us if you are unable to locate the shut-off valve on your own and we will plan a time for one of our service specialists to come out to your home to assist you as soon as possible.
  5. If you have an electric or gas water heater, follow the actions outlined in this section.

Electric Water Heater

It is recommended that you turn off the power at the breaker before working on the water heater tank if you have an electric water heater and are having trouble with it. Simply turn off the circuit breaker.

Gas Water Heater

  • For gas-powered water heaters that are leaking, we recommend that you turn off the gas supply before attempting any repairs. On the gas line going to the tank, there should be a specific gas shut-off valve to prevent the flow of gas. See the image below for a visual representation of a gas water heater being turned off. Once your water and electricity have been switched off, you will be able to more accurately analyze the problem and discover where the leak is coming from in more detail. Check the input and output connections. Leaks are frequently found at the points where pipes connect to your water heater. Examine the connections for the cold water input and hot water output. Is there a problem with any of the fittings? It’s possible that all they require is to be tightened using a pipe wrench.
  • Make that the pressure release valve is working properly.
  • If there is an excessive buildup of pressure, the pressure relief valve, also known as the T&P valve, may be activated to discharge water as a safety precaution. It is possible that pressure will build up at the valve if your thermostat is set too high or if the water pressure to your home is excessive. Check your thermostat settings to ensure that the temperature is not set too high. A pressure gauge at a hose bib may be used to check the pressure in your home (you can also check the pressure in your car). What temperature setting should you use for your water heater? The Department of Energy suggests that you set your tank-based water heater to 120 degrees Fahrenheit instead of the default setting of 140 degrees Fahrenheit that most manufacturers use. There are two possibilities when it comes to water leaking from a T&P valve: either the valve is performing its function properly by releasing water as pressure develops, or the valve itself is defective. However, if your thermostat is not set too high and you are still experiencing leakage, the issue may be with the valve itself
  • check your water pressure. Besides checking the pressure and temperature, it’s a good idea to check the humidity. You may check the pressure by attaching a pressure gauge to the hose bib outside your home and running it through it. What should I do if my incoming pressure is excessive? According to regulations, your inbound water pressure should not be greater than 80 PSI, and if the pressure is greater than 100 PSI, we highly recommend that you install a pressure decreasing valve. Not only might your water pressure be producing a leak, but it could also be causing damage to your fixtures.
  • Look at the bottom of the water heater for leaks.
  • Identifying the cause of a leak might be challenging in some cases, particularly if water is pooling underneath the tank itself. It’s possible that water leaking from a valve will run down the sides of the tank, creating the appearance that it’s coming from the bottom while in fact it’s coming from the top or sides.

Loose Drain Valve:

Lagging drain valves in water heaters are one of the most prevalent causes of water heater leaking. Try tightening the valve with a wrench until it is snug, but be cautious not to over-tighten it if water appears to be flowing out.

Too Much Pressure:

It is possible for a water heater tank to build up excessive pressure, which might result in leaks. This can happen if the water temperature is adjusted too high or if the water pressure from the outer water source is too high for the tank to handle.

Cracked Storage Tank:

  1. Hot water heaters are constructed using a storage tank that is coated with glass.
  2. Over time, the natural minerals in the water might calcify and deposit on the interior of the tank, causing it to get clogged.
  3. These have the potential to fracture the glass lining of your water heater, causing it to leak.
  4. Additionally, water expands when it is heated.
  5. Over time, this expansion places stress on the heater’s glass lining, which might eventually lead it to crack and break.

Unfortunately, if this occurs, your hot water heater will need to be replaced since the breaks in the glass liner are irreparable and cannot be repaired.Occasionally, these leaks will not have an impact on the performance or functionality of the device, and the individuals who experience them will choose to wait to replace the water heater.Providing the leaking water does not cause damage, this is OK, but the unit will need to be replaced at some point in the future.

Other Reasons:

Your water heater may be leaking for a variety of reasons, including broken fittings, poor draining, and just old age. Performing some troubleshooting on your own is always a good idea, but calling in a professional will always be the safest and most effective method to avoid any long-term and expensive damage to your property.

Your Water Heater Isn’t Producing Hot Water

  1. If your hot water heater is no longer supplying hot water and the tank is supplied by electricity, check to see if the fuse at the breaker has blown and that the breaker has not been reset.
  2. Whether you have a gas hot water heater, you may also check to see if the pilot light is still lit to see if the heater is still operational.
  3. If neither of these basic solutions are successful, contact to schedule a service call with a skilled technician to come to your house and assess the situation.

My Gas is Leaking – I Smell Gas!

  1. If you suspect a gas leak at the water heater, you can shut off the gas at the dedicated gas shut off valve located on the gas line leading to the water heater and turn off the water heater.
  2. If you suspect that you have a gas leak concern that has not been resolved, you can contact Fast for service at (866) 264-9642.
  3. It is usually recommended to notify your energy company as soon as possible in the event of a significant gas leak or emergency.

After an Earthquake, Protect Your Home

  • If you smell gas, move the meter to a safe location outside your home. Turn the gas valve 14 times from the ON position to the OFF position.
  • Make contact with your natural gas business.

Having to deal with a leaky water heater first thing in the morning is not the best way to start the day. It is possible to avoid an emergency from turning into a disaster, though, by following these procedures.

The location of the leak in a water heater is critical in determining how to repair it. It is possible that you may need to fix your water heater, bring in a professional to assist you, or replace it totally after going through these troubleshooting methods.

Look at the Water Supply Lines

  1. The plumbing lines above the water heater should be the first location to look for leaks.
  2. It is quite easy for a drip from above to spill down onto the top of the water heater and even work its way through the insulation, making it appear as though the leak is emanating from the tank itself.
  3. Check the plumbing pipes above the water heater, and if required, use a stepladder to reach the pipes.
  4. Make sure to pay particular attention to the water supply pipes that go to the water heater.
  5. These might be either hard pipe connections or flexible supply tubes, depending on the application.

  • Before removing the water supply tubes, make sure that the water has been turned off by turning on the hot side of a faucet anywhere in the home and checking to see if water is still flowing.
  • If the water has been effectively shut off, there should be no water coming out of the water heater at this point.


If you are not familiar with or comfortable working with your heater, contact a professional—and keep in mind that only licensed specialists should operate on gas pipes.

Inspect the Water Heater Nipples

  1. The water heater nipples, which are located on the top of the water heater and link the water heater to the cold water intake pipe and the hot water exit pipe, are another popular location to detect leaks in the water heater.
  2. Due to the fact that they are the thinnest area of the
