What Does It Mean When The Water Heater Is Leaking?

5 Fixes for Water Heater Leaks

  1. The methods for repairing a leaky water heater can range from being really simple to being extremely difficult.
  2. Many individuals jump to the conclusion that their water heater has to be replaced at the first indication of a leak, but this is not always (or even typically) the case, according to the experts.
  3. Many potential solutions are really quite easy and affordable, and in some cases, simply replacing a faulty element may significantly prolong the life of the water heater by many years.
  4. Consider the following factors when assessing the source of an oil leak and selecting the most appropriate repair method.


  • Temperature and pressure release valves
  • Water heater nipples
  • Drain valve
  • Water heater (in the case of a complete replacement)
  • Flex tubes for the water heater

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.

Flexible water supply tubes are the most typical source of leaks above the water heater, owing to the fact that these tubes frequently break long before the water heater has to be replaced.If there is insulation surrounding the supply tubes, it should be removed so that the tubes may be inspected and replaced if necessary.First, cut off the gas (for gas heaters) or power (for electric heaters) that is connected to the heater before attempting to replace the flex lines on the water heater.When it comes to gas heaters, the directions for turning the gas valve to the off position are often located on the front of the unit.When it comes to electric heaters, you may normally cut off the power by using a disconnect button located near the heater or a separate circuit breaker.After that, turn off the water supply to the water heater.

  1. This will be a shutdown valve that will be installed on the cold water line that leads to the hot water heater.
  2. 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.
  3. 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 nipple, it is not uncommon to discover leaks in them.
  3. This can be difficult to distinguish from a leak at the supply tube, but if you have already changed the supply tube and are still noticing leaky water, the nipple is most likely the source of the problem.
  4. Water heater nipples can be tough to remove and will need the use of a pipe wrench and considerable strength to complete the task.
  5. Before beginning this repair, make sure that the water is turned off and that it is still turned off.

As wrong removal can create a variety of problems, this is typically a job best left to the professionals.


It may be necessary in some states to use a special fitting known as a dielectric union when attaching galvanized steel nipples directly to copper pipes since the copper pipes conduct electricity. The dielectric unions prevent corrosion from occurring because the contact of galvanized steel and copper generates a moderate electrical charge when they are in contact.

Look at the Temperature & Pressure Release Valve

  1. It is also conceivable that a leak will develop in the temperature and pressure (T&P) valve.
  2. A leak at the T&P valve is a more serious condition, and you should take the necessary steps to determine the source of the leak.
  3. A T&P valve will not typically drip or leak unless there is a more serious problem with the valve itself.
  4. If the valve was recently removed, it’s conceivable that it’s no longer sealing correctly as a result.
  5. If the problem persists, tightening the valve or replacing it with new plumber’s tape wrapped around the threads may be the solution.

Alternatively, if the water heater is heating the water too much, it is possible that the high pressure is causing the T&P valve to leak.If you don’t currently have a water expansion tank in your plumbing system, you may be able to solve the problem by lowering the water temperature or installing one.The presence of a leaky T&P valve may signal that the total water pressure in your house is excessive and that the pressure regulator is not functioning correctly.if the water pressure in the home appears to be normal, and the water heater appears to be heating normally, it is possible that the T&P valve is malfunctioning and needs to be replaced.Ensure that the water has been turned off and that there is no pressure in the tank before attempting to replace the valve.You can relieve pressure by releasing the lever on the T&P valve or by turning on a hot water faucet someplace in the home, depending on your preference.

  1. Call a professional plumber for assistance in determining whether or not there is still a problem and in resolving the issue if you are unable to do it yourself.


Always keep in mind that you’re working with extremely hot water that’s being forced through you. Take the necessary safeguards. Experts strongly advise calling in a professional for repairs because there are so many things that might go wrong. Gas appliances should only be repaired by professionals who are properly licensed.

Check the Drain Line

  1. Another typical problem is a leak in the drain valve, which is located at the bottom of the water heater.
  2. A typical problem with water heaters is that the drain valve does not completely close after they have been drained or flushed.
  3. Alternatively, you may cap the drain valve with a hose cap or totally replace the drain valve with a new one.
  4. Before removing and replacing this valve, you will need to turn off the hot water and allow the water heater to cool down completely.

Examine the Tank

If none of your previous examinations revealed a source of the leak, it’s probable that the tank within your water heater has developed a problem. It is more common for this to be a massive flooding leak, rather than a little trickling leak. A water heater that has ruptured and is leaking will not be able to be repaired and will be need to be replaced.

How Does My Gas Furnace Work And Does it Produce Water?

  1. Who knows what you’re thinking: what does water have to do with my furnace?
  2. Let’s get this party started!
  3. For begin, let’s take a look at how your furnace operates.
  4. It is the thermostat’s responsibility to deliver a signal to a control board placed within the furnace when the interior temperature has dropped below its predetermined temperature.
  5. The control board will then initiate the heating cycle.

This begins with the activation of an ignition switch, the opening of the gas valve, and the activation of a draft fan in order to initiate combustion.The heat exchanger is heated by the combustion.All of the flue gasses produced inside the heat exchanger are vented to the atmosphere outside through the exhaust tube.The blower fan then blows cold air from within your home past the heat exchanger, completing the cycle.This is the point at which the air absorbs the heat and is propelled through your home’s ventilation system to heat the inside of the building.That is exactly how warm air is created!

  1. Do you understand the fundamentals?
  2. So, where does the water enter the picture?
  3. There is no water produced by a typical furnace, which is also known as a standard efficiency furnace.
  4. Although condensation will occur if you have a high efficiency furnace (90 percent efficiency or higher), it will not occur if you have a low efficiency furnace (50 percent efficiency or lower).

The term condensing furnace is used to describe high-efficiency furnaces, whereas the term non-condensing furnace is used to describe standard-efficiency furnaces.Heat Exchanger 1: Main After the burning gas has exited the primary heat exchanger, it is sent to the secondary heat exchanger.The secondary heat exchanger is the location where further heat exchange occurs with the exhaust or flue gas.This results in the formation of water vapor forms.(Learn more about Heat Exchangers by visiting this site!) A greater amount of heat is discharged into the secondary heat exchanger as water moves from its vapor state to its liquid state.

As a result, the furnace operates at an even higher level of efficiency.The condensation is then discharged into a condensate pump or a floor drain when it has formed.

What kind of furnace unit do I have?

  1. Let’s take a look at your furnace and see what it is made of.
  2. It is pretty simple to determine the sort of furnace you have and to narrow down the source of the leak.
  3. Pay attention to the exhaust pipe.
  4. A condensing furnace is one that uses white PVC pipe for the heat exchanger, which means it has a high efficiency.
  5. Compared to other materials, metal exhaust pipes have a standard efficiency rating and do not generate condensation.

Why is High efficiency furnace Leaking Water?

  1. Condensation is produced when the exhaust gases from a high-efficiency furnace are released into the atmosphere.
  2. This condensation creates a substantial quantity of moisture on the PVC pipe, and it must be drained either into a floor drain or through a condensation pump to be removed from the system.
  3. When condensation is unable to drain correctly, it results in a leakage of fresh water.
  4. Allow me to give you a few examples:

Leaking From Condensate Drain Hose

Depending on how much debris, dirt, and dust accumulates in the drain hose, which slopes downward from the PVC exhaust pipe, the drain hose might get stuck. Condensation leaks occur when any of the tubing that assists in the draining is broken, disconnected, or blocked, as described above. Hose for Draining Condensate

Inducer Assembly Leaking

The condensation then travels down the exhaust/flue pipe, down the condensate drain hose, and into the inducer assembly, where it condenses. If there is a fracture in the inducer assembly, water will be able to flow out of the furnace.

Leaking From Condensate Drain Line

A condensate drain pipe is used to remove the water that has condensed on the surface. If there is a loose connection, fractures, or holes in this, it might result in a water leak. Additionally, if the drain line becomes clogged, the condensate might back up and produce a water leak.

Leaking Out Of The Condensate Trap

An overflowing or blocked condensate trap can cause condensate to back up and overflow from the furnace. It should be noted that not all high-efficiency furnaces are equipped with a condensate trap.

Condensate Pump Leaking

  1. The condensate pump is the final destination for the condensate once it has been collected.
  2. This is another another component that has the potential to clog, resulting in a leak.
  3. A clogged drain, or even a partially clogged drain, will cause the furnace to begin to leak.
  4. Water on the floor near your high efficiency furnace unit, or water or rust stains within the cabinet, indicate that your furnace’s drainage system needs to be repaired or serviced.
  5. Water can back up into the furnace due to a failing pump, which can cause a leak in the furnace itself.

In this circumstance, a professional will be required to take its position.Most condensate pumps have a life span of 3 – 5 years, after which they may not work at their peak.Condensate pump that is overflowing

Why is Non-High Efficiency Furnace Leaking Water?

Unless your furnace unit is a traditional furnace that operates at a specified efficiency, it will not create any waste heat or water. If there is standing water near your furnace, it is most likely the result of another appliance malfunction. Some appliances to keep an eye out for are as follows:

Water Leaking From Air Conditioner

Water is generated when your air conditioning machine is operating, making it a typical source of leaks. There are a variety of reasons why your air conditioner may be leaking, including:

Damaged Drain Pan

  1. All air conditioning systems are equipped with a primary drain pan, which is placed beneath the evaporator coil.
  2. Some air conditioning units are equipped with a secondary drain pan that is located beneath the unit.
  3. The drain pan’s purpose is to collect any condensate that may accumulate.
  4. Excess water will spill or leak out if there is a break or hole in the structure.
  5. The attic drain pan is leaking water.

A Frozen Coil

If the evaporator coil in your air conditioning unit freezes, your AC unit will begin to leak. Evaporator coil that has been frozen

Clogged Drain Line

The drain will get disconnected from the drain pan if the drain line becomes blocked and no water is able to move through it. The water will then trickle and pool around your air conditioning unit.

Failed Condensate Pump

If water cannot move through a blocked drain line, the drain will become disconnected from the drain pan. The water will leak and pool around your air conditioning unit at that point, damaging it.

So, what should you do if you notice water leaking from the top of your water heater to prevent more damage?Fortunately, your friends at Benjamin Franklin Plumbing Bay Area have put together this helpful do-it-yourself guide to assist you in diagnosing and resolving this frequent water heater problem.Before we get started on the remedies, let’s take a brief look at some of the likely reasons of the problem.Typically, leaks from the top of the water heater are caused by one of the three connections at the top, as seen in the diagram below: 1) A hot water generating connection is installed.2) A water-generating connection that produces cold water 3) A connection that allows pressure to be released

What to do when you see water coming out of water heater’s top

According to the information above, it’s critical to thoroughly inspect these three connections at the top of your hot water heater if you suspect a leak.It will be decided by which of these connections is insecure as to which course of action you will take.Most of the time, one of these connections has to be tightened, which you may do by hand if necessary.

To tighten the loose fitting, all you need is a wrench.This frequently results in the leak being repaired immediately.1.

  1. Wipe down the damp places on the top of your water heater with paper towels to ensure that it is completely dry.
  2. 2.
  3. Next, pay attention to where the water first appears to be coming from.
  4. 3.
  5. If you discover that a leak is still occurring, cut off the power source immediately to avoid any electrical problems in the future.

If you have a gas water heater, make sure the gas supply is turned off.Make a clockwise turn on the gas valve, which should be found either to the side or behind your water heater at the end of the gas supply line.If you have an electric water heater, make sure the breaker switch in your home’s circuit box is turned off.If you are unable to locate the water heater’s label, you should switch off the main breaker.It’s possible that the pressure relief valve (as seen in the figure above) is defective, or that debris has accumulated inside the valve, which is interfering with its operation.

  1. This may be tested by placing a bowl just below what is known as the overflow tube.
  2. 2.
  3. Next, lift the tab on the pressure relief valve to release the pressure.
  4. You’ll want to be certain that it is pointing directly out.

The valve should then be opened, allowing any material that may have been hiding to be flushed away.3.If you discover that the valve continues to leak after doing these steps, you will most likely require a replacement.Simply tighten the pressure relief valve, or try wrapping Teflon tape across the threaded connection if the pressure relief valve detects a leak at the connection.

  • Is the source of the leak closer to the bottom of the water heating system? Else, proceed to section titled ″My water heater is leaking from the bottom″
  • otherwise, read on.
  • Is there a leak in the tank itself? If this is the case, go on to the section titled ″If the water heater tank itself is leaking.″

Do you require a specialist to fix your water heater as soon as possible? Simply call us and we will dispatch a plumber to your location.

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…

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.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.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.

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.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…

.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.When the levels in the tank reach an unsafe level, the valve opens and emits hot water to reduce the pressure within the tank.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.

As a result, if everything is functioning properly, you should only ever see water dropping towards the floor when your TPR valve is activated.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.

  1. This is a critical safety feature that prevents your water heater from rupturing as a result of excessive pressure.
  2. 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…

You’ll see water coming from this location…Your anode rod is a long, slender rod that is installed inside your water heater to prevent corrosion of the tank.It is made of copper.

Because corrosive substances in your home’s water ″eat away″ at the interior of your water heater over time, you should consider replacing it.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).

  1. 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…

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.As you can see, water expands as it is heated.Additionally, because water expands after being heated, it might often overrun the available area within the tank.

This results in extra water being transferred to the expansion tank, which helps to reduce the pressure levels inside the water heater.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.

  1. 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.
  2. 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…

.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.So, what does all of this imply?Basically, it signifies that your water heater’s tank has a dangerously high level of pressure inside it.

When the TPR valve (placed at the top of the water heater) detects excessive pressure levels, it automatically opens to drain the water.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.

  1. What to do: Have your water heater inspected by a professional as soon as possible.
  2. 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…

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).The drain valve, on the other hand, may get blocked with particles or silt from the water over time.And when this happens, the valve may not seal correctly, allowing water to spill out.

The best course of action is to have a professional replace the drain valve.

If the water heater tank itself is leaking…

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

What to do: Call a plumber right once to get the water heater fixed as soon as possible.

Water Heater Leaking From The Bottom? (DO THIS)

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. Check see this article: Water heater leaking from the top

Leaking from the Bottom of the Tank: Finding the Source

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).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.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.

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

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.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.Turn the valve control counterclockwise to ensure that the bottom valve is entirely closed.

If necessary, replace the bottom valve.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.

  1. 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.
  2. Drain the tank by opening the drain valve and allowing it to empty.
  3. Replacement valves for hot water heaters are readily available at most hardware stores and may be easily installed with a simple socket wrench.
  4. To remove the existing valve, turn it counter-clockwise from its position.
  5. 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

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.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.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.

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.If the temperature is normal, it is probable that the pressure relief valve will need to be replaced.

Leaking Tank

Water heaters that are not cleaned out on a regular basis might develop silt buildup in the tank.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.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.

A leak in an inside closet has been reported in the past, resulting in a consistent supply of water under the crawl space.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.

  1. A leaky tank is an evident symptom that a water heater needs to be replaced and should be addressed immediately.

  4. 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.
  5. 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.


In some cases, condensation on the water tank of the water heater will be present.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.Allow the tank to lie idle for many hours while the electricity and gas are shut off to conserve energy.

Having the leak cease indicates that you are experiencing condensate in your home.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.

  1. To show exactly how well-insulated modern models have grown, look no farther than our list of suggested water heaters.
  2. 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.
  3. Condensation is frequently caused by a temperature differential between the inside of the tank and the outer air outside the tank.

what to do with a leaking water heater

Water heaters are built to last a long period, but even the greatest ones can develop leaks over time.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.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.

First and foremost, determine the source of the leak.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.

  1. Are any of the fittings dripping or are there any other symptoms of leakage that you’re aware of?
  2. Make a thorough search of your surroundings for any other potential water sources.
  3. Where did you find the water?
  4. Was it near a window or another water pipe?
  5. 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.

Please contact us at (866) 264-9642 if you need assistance working through this.If the valve in your home is damaged, you can turn off the water supply to your home.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.

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.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. Alternatively, if the leak is coming from the bottom of the tank, it is possible that the tank itself is damaged, in which case it will need to be replaced.
  • Make that the drain valve is working properly.
  • The drain valve, which is located towards the bottom of the tank, should be entirely closed, so ensure sure there is no water flowing from this place. If it is leaking, it is possible that the washer inside has become worn and has to be replaced. If you are still unable to locate the source of the leak, please contact us and one of our professionals will be able to assist you
  • No matter what you discover, it is always recommended that you have a professional evaluate your water heater if you discover any leaks.

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:

Hot water heaters are constructed using a storage tank that is coated with glass.Over time, the natural minerals in the water might calcify and deposit on the interior of the tank, causing it to get clogged.These have the potential to fracture the glass lining of your water heater, causing it to leak.

Additionally, water expands when it is heated.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.

  1. 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.
  2. 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

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.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.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!

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.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.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.

  5. Continue reading to learn how to inspect your system for leaks and other problems.

2. Inspect the Drain Valve

You are undoubtedly aware that all water heaters are equipped with drain valves, which are located around the base of the tank.Drain valves allow you to do maintenance on a tank by emptying the contents of the tank.If you discover that the water heater is leaking from the bottom drain valve, you may repair the problem using this procedure.

Simply said, you should empty your tank on a regular basis, as this will aid in the removal of dirt and other material that has accumulated inside your tank.Failure to drain it to remove sediments will result in harm to the interior component of the machine.If you notice water on the floor near your tank, it is most likely due to a leak in the drain valve.

  1. Due to the following circumstances, we are experiencing this issue:

Damaged Drain Valve

Leakages from the valve nozzle might occur from time to time, as well.If this is the case, double-check and make certain that it is securely closed.To put it another way, before replacing the valve, make sure the nozzle is working properly.

It’s possible that tightening the knob with your hand will resolve the issue and spare you the hassle.If, on the other hand, the leak persists even after you have tightened the knob, the drain valve is defective and should be replaced.If you are unable to replace it right away, you should cover it to prevent more leaks from occurring.

  1. This procedure will assist you in preventing water damage until you have the funds to repair it.
  2. Installing a water sensor alarm to inform you whenever there is a leak will help to alleviate some of the tension.
  3. These water sensors are excellent investments in the long run.

Is the Drain Valve Leaking?

If water is leaking out of the drain valve from the bottom, this indicates that the valve is unable to contain water. You have no choice but to purchase a fresh new valve because the situation may worsen in the future unless you act quickly. For a replacement, you may either call a repair firm or attempt it yourself if you know what you’re doing.

3. Internal Tank

The majority of leaks occur as a result of a defective hot water tank.If this is the case, then there is an issue with the inside part of the tank, which is described below.When there is an issue like this, water leaks out slowly and collects at the bottom of the tank.

The majority of the time, this is caused by dirt accumulation within the internal tank.When dirt collects in a tank and is not flushed out on a regular basis, it causes the tank to rust and corrode.With time, this flaw will result in leaks being produced.

  1. In certain cases, a leak from the hot water tank indicates that you require a whole new water heater installation.
  2. However, it is recommended that you contact a well-trained plumber as soon as possible to come examine your tank or have it replaced.

4. Condensation

Condensation on the outside of your tank can be caused by a variety of factors.Condensation can occur when an item has reached the end of its useful life and is unable to perform properly.Additionally, this might occur when the thermostat has been programmed too high or when the insulation has deteriorated.

You may resolve this issue by cutting off the gas or electricity supply to your water heater for 6 hours and then re-connecting it after that period.While your water heater is turned off, you should check to see if there is any condensation on the outside of the unit.To be sure you didn’t miss anything, lower the temperature on your thermostat and switch on the gas or electricity again.

  1. It is possible that you have damaged insulation and may need to purchase a new water heater if you continue to experience leaks and dampness.
