What Do I Do If My Hot Water Heater Is Leaking From The Top?

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.

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.

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.

When your water heater specialist arrives to begin work, they will drain your tank. However, if your tank is leaking excessively, you may want to drain it promptly to avoid water damage to your property. The following actions should be followed if you need to empty your water heater before a professional arrives: After you’ve shut off the water and electricity, follow these steps:

  1. Connect a garden hose to the drain valve at the bottom of the tank and run it outside on the ground to remove the water. Make certain that the tank is drained to an appropriate area, such as a gutter drain or a sink. It is not recommended to discharge the water onto your lawn or driveway since the silt and rust from the tank might hurt your grass and discolor your driveway.
  2. Activate the drain valve that is connected to the hose.
  3. Pulling up on the pressure release valve on the tank’s top will allow it to be opened.
  4. Allowing the water in the tank to drain is recommended.

Again, unless you are concerned about catastrophic damage to your home, you do not need to be concerned about draining your water heater.If you need assistance, our professionals would be pleased to assist you.Following these initial procedures after discovering a leak can be quite beneficial in preventing water damage from accumulating.Any inquiries or concerns you may have should be sent to (866) 264-9642, which is our toll free number.

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.

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

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.

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.
  1. What to do is as follows: If the TPR valve is leaking, it should be replaced by a professional.
  2. This is a critical safety feature that prevents your water heater from rupturing as a result of excessive pressure.
  3. 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.
  1. 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).
  2. 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.
  1. What to do is as follows: The expansion tank should be inspected to establish the location of the leak.
  2. 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.
  3. 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.
  1. In most cases, a hissing noise is produced by a TPR valve that is discharging its contents.
  2. What to do: Have your water heater inspected by a professional as soon as possible.
  3. 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 Bottom (Tips to Fix & Prevention)

  • A leaking water heater from the bottom may cause a great deal of harm.
  • Anyone who has ever seen water below a water heater knows that it is a sight that no one enjoys.
  • A leaky water heater, on the other hand, does not always indicate that you need to replace it.
  • Throughout this article, you will learn how to identify a leaky hot water heater from the bottom up.
  • We will also reveal to you some simple procedures to do in order to resolve the issue.

What to Do When Water Heater is Leaking From Bottom

Step One: Trace the Leak

Water heaters that leak from the bottom might be caused by a variety of different problems in the unit’s various components. Because of this, you must determine what caused the leaks in order to repair or replace the faulty component, if necessary. Here is a list of the areas you should pay attention to.

1. Temperature & Pressure Relief Valve

  • It is necessary to keep an eye on your T&P valve if you are not utilizing a tankless gas water heater.
  • When the water becomes too hot, the temperature and pressure valve opens, releasing the pressure.
  • The purpose of this tube is to guarantee that any water that leaks from the bottom of the water heater is routed away.
  • This keeps the environment safer by reducing the likelihood of water breakouts.
  • If you discover that your water heater is leaking from the bottom, thoroughly inspect your discharge tube for any leaks that may exist.
  1. If there is standing water on the floor, the problem is most likely caused by the T&P relief valve.
  2. If, on the other hand, the problem is caused by the temperature and pressure valve, you will need to call in a plumber for assistance.
  3. You have two options: either contact a handyman to address the internal pressure issue or have the valve completely replaced.
  4. Many experienced plumbers have indicated that you should inspect the T&P valve on a regular basis since it is a safety feature for a water heater and should be checked regularly.
  5. The majority of the time, when the pressure in the tank is too high, the temperature and pressure valves begin to leak.
  • 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.
  1. If you notice water on the floor near your tank, it is most likely due to a leak in the drain valve.
  2. 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.
  1. If you are unable to replace it right away, you should cover it to prevent more leaks from occurring.
  2. This procedure will assist you in preventing water damage until you have the funds to repair it.
  3. Installing a water sensor alarm to inform you whenever there is a leak will help to alleviate some of the tension.
  4. 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.
  1. With time, this flaw will result in leaks being produced.
  2. In certain cases, a leak from the hot water tank indicates that you require a whole new water heater installation.
  3. 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.
  1. To be sure you didn’t miss anything, lower the temperature on your thermostat and switch on the gas or electricity again.
  2. 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.

Step Two: Mitigate Future Water Damages

After you’ve discovered the leak, switch off the water and electricity to the device and press the emergency shutdown button. If your water heater does not have this function, the instructions outlined below will take you through the process.

Switch off the power

  • Finding and turning off the main switch on an electric tankless water heater is the first step.
  • The primary switch has a label on it to make it easier to find.
  • The majority of water heaters are equipped with a 240V circuit breaker.
  • This circuit breaker is intended to shut down the device in the event of an emergency.
  • The on/off switch or button on the unit of a propane tankless water heater should be easily accessible.
  1. This switch may be found at the base of the heater; simply press the off button to turn it off completely.

Switch Off the Water Supply

  • The water heater will only cease replenishing itself when the water supply is turned off.
  • To put it another way, your water will not stop flowing until you turn off the main supply.
  • As a result, it is recommended that you switch off the water supply when traveling or going on vacation.
  • To cut off the water supply, turn the valve or lever to the right until it is completely closed.
  • This valve may be found on the top of your water heater, near the evaporator.
  1. This valve acts as a switch, allowing water to enter your home while also turning off the water supply.
  2. The majority of individuals who use a gas water heater believe that turning it off makes them feel safer.
  3. It is possible to turn off the gas by turning off the switch or lever, albeit this is not required.
  4. This lever, which is placed at the bottom of the device and comes in a variety of vibrant colors, may be adjusted.
  5. To switch off the gas, turn the knob to the off position.
  • If you follow these measures, you will be able to prevent water from entering your house, but this does not imply that your tank is empty.

When Leak Get Out Of Hands

  • A water heater that is leaking from the bottom is something that should be taken carefully.
  • The first step to do if the leak gets too bad and has flooded the overflow pan is to completely empty the tank.
  • The drain valve may be found at the bottom of the tank, and it should be accessible.
  • Examine the valve to see if it is the source of the leak (85 percent of the time, the fault comes from the drain valve).
  • Get a hose and connect it to the valve, then route the water to a drain.
  1. After that, turn the valve to the open position.
  2. Instead of allowing the water heater to leak from the bottom, this will totally drain the water that has accumulated in the tank over the course of time.

Step Three: Think Of the Next Step to Take

  • Your degree of technically, the amount of comfort you desire, and the gear you possess will determine whether you require the services of a professional plumber or whether you can complete the job yourself.
  • It is not possible to repair or replace your internal tank if your water heater is not functioning properly.
  • However, if the problem stems from the drain valve or pressure valve, it may be possible to repair it.

How to Prevent Water Heater Leaking from the Bottom

  • It becomes increasingly difficult to keep the water heater from leaking after a while.
  • Nonetheless, a water heater, like all other equipment, has a limited lifespan that must be exhausted eventually.
  • A conventional water heater has a lifespan of 8 to 12 years, but with regular care, it may last for many years longer than its expected lifespan.
  • However, it is important to note that regular examination of the anode rod and an annual drain of your unit might help to extend the life of your water heater.
  • Draining it once a year will also help to avoid rust and cracking of the steel inner tank and other metallic components of the tank.
  1. Keep in mind that tank failures are frequently caused by corroded tanks.
  2. The procedure for replacing the anode rod is straightforward.
  3. All you have to do is climb to the top of your tank and carefully detach the anode rod from its mounting.
  4. After that, look for any accumulations.
  5. If the degree of build-up has grown too severe, you may want to consider having it replaced.
  • Isn’t it simple?
  • The simplest method of emptying a heater is to place an empty bucket directly beneath the valve that allows water to flow out.
  • This, on the other hand, can also be accomplished by connecting a hose directly to the valve in question.
  • It is not necessary to remove the water from the tank until the tank is completely empty.

When the water begins to flow smoothly, you may choose to halt the procedure and turn off the valve.The tank temperature and water pressure are two more critical parameters to which you should pay particular attention.Keeping track of these details might assist you in preventing water heater leaks from the bottom.When it comes to tank wear and tear, the degree of water pressure and tank temperature are important factors to consider.The amount of care you devote to these two elements will influence the length of time your water heater will last.

  1. So, what should you do if you notice water leaking from the top of your water heater to prevent more damage?
  2. 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.
  3. Before we get started on the remedies, let’s take a brief look at some of the likely reasons of the problem.
  4. 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.
  5. 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.
  2. Wipe down the damp places on the top of your water heater with paper towels to ensure that it is completely dry.
  3. 2.
  4. Next, pay attention to where the water first appears to be coming from.
  5. 3.
  • 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.This may be tested by placing a bowl just below what is known as the overflow tube.2.Next, lift the tab on the pressure relief valve to release the pressure.

  1. You’ll want to be certain that it is pointing directly out.
  2. The valve should then be opened, allowing any material that may have been hiding to be flushed away.
  3. 3.
  4. If you discover that the valve continues to leak after doing these steps, you will most likely require a replacement.
  5. 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.

If Your Hot Water Heater Is Leaking from the Top, Follow These Tips

  • When your hot water heater is leaking from the top, it’s critical that you address the problem as quickly as possible to avoid more damage.
  • What is the reason for the urgency?
  • A leak at the top of your water heater can allow the water to drain down, causing electrical difficulties and other unneeded hassles as the water heater cools.
  • In addition to this, a leaking water heater tank can cause structural damage to the surrounding area.
  • This can include destroying your carpet, causing damage to the lowest portion of your walls, and allowing mold to grow beneath your flooring.
  1. The very first thing you’ll want to do is switch off the water supply to the building.
  2. The next step is to pinpoint the source of the leak.
  3. The situation might become complicated because there are a variety of factors that could be triggering the leak.
  4. Once you’ve determined where the leak is coming from, you may proceed with the rest of the necessary repair work.

Faulty water inlet valves

  • An issue with the water input valve on your hot water heater is one of the most prevalent causes of top-of-the-line leakage in hot water heaters.
  • Examine the top of your water heater for any signs of leaks.
  • If you see a pool of water, this is almost certainly the source of the problem.
  • In order to properly tighten the water heater handle, first find and tighten the nut that is linked to it.
  • In the vast majority of situations, this will resolve your issue.
  1. Even after the nut has been correctly tightened, you may notice that your device is still pouring.
  2. If this is the case, your valve is most likely broken and will need to be completely replaced.

Your pipe fittings are loose

  • Another reason your hot water heater may be leaking at the top is that a pipe fitting may have come loose.
  • Make a visual inspection to check if any of your water intake and outlet fittings are leaky or otherwise compromised in any manner.
  • To correct this situation, you’ll need to arm yourself with a wrench and tighten the loosened pipe.
  • Unless the fittings are broken beyond repair, they will need to be changed out.
  • For the majority of homeowners, replacing the fitting is not a difficult task.

The joints on the water heater are leaking

  • When inspecting your water heater tank, look for a stripped threaded nipple or a loose connection that may indicate the equipment is malfunctioning.
  • Remember that a tank with copper tubing is considerably more difficult to repair than a water heater with threaded plumbing, so keep this in mind.
  • It is possible that you will need to hire a professional if you do not have the requisite skills to do the necessary repairs.
  • If you want to make future repairs easier, you may also invest in water-rated PVC or threaded tubing and re-plumb the tank yourself to save money and time.

Faulty pressure valves

  • The temperature and pressure relief valves on many water heater tanks are located on the side of the tank, which is convenient.
  • Some types, on the other hand, have these valves situated right at the very top of the machine.
  • If your hot water heater is constructed in this manner, it is possible that this is the cause of your water heater leaking at the top.
  • Take a look at: In the event that your water heater’s pressure relief valve leaks, there are several things you may do.
  • Begin by visually evaluating the two valves to determine if there is any leaking or leakage.
  1. Look for fractures and breaks in the threading of the valve, as well as any other flaws or defects.
  2. It’s usually preferable not to waste time trying to remedy a problem with either your temperature or pressure valve, and instead simply replace it with a new valve in the majority of circumstances.
  3. Begin by removing a little amount of water from your tank before attempting to replace any of these valves.
  4. It’s only necessary to empty it to a level that is just below the two control valves.
  5. Turn on the hot water in either the kitchen or the bathroom by going to the appropriate location.
  • While you are replacing the valves, leave the engine running.
  • Prepare yourself with a pair of channel locks and begin unscrewing the defective valve as soon as possible.
  • However, it is critical that you thoroughly inspect the area for rust and corrosion before proceeding.
  • If you do discover rust or corrosion around or in the area where the valve was removed, you’ll want to replace your water heater with a fresh new one right away.

Rusted or corroded hot water heater tank

  • If you have a lot of rust or corrosion on the inside of your water heater tank, this might be the source of your problems.
  • Tanks that are just out of date or that have been neglected tend to have a plethora of issues and should be replaced as quickly as possible.
  • Another sign that your water heater needs to be replaced is if you observe water starting to shoot out of the top of the appliance.
  • When this occurs, you’ll want to shut down the water supply to your water heater as soon as possible.
  • This is often accomplished by rotating the knob for the cold water in a clockwise direction.
  1. Look just above the water heater for this knob, which is located just above the water heater.
  2. When your water heater sprays, it is most likely due to rusty or corroded pipes in the system.
  3. If you find yourself in this predicament again, you’ll want to replace the entire unit.

Other potential issues

  • Even if none of the concerns listed above apply to you, the fact that your hot water heater is leaking from the top seam might be the consequence of one of a few additional difficulties. If your water heater is fueled by gas, you’ll want to check to see if there’s any possibility that rainwater may have found its way into the flue pipe of your unit. This sort of event can occur during severe storms and high-wind storms, for example. It is possible that this is the case, and you will see a pool of water on the top of your unit. It is critical to clean your water heater tank at least once a year in order to remove the sediment that has accumulated at the bottom. If your water heater is between two and three years old, now would be a good time to inspect the anode rod for corrosion. To accomplish this, gently remove the gadget and thoroughly examine it. There may be some pitting and rust visible. That is completely OK. If, on the other hand, you notice huge chunks of metal gone from the surface, this is a very strong sign that the rod will need to be changed. If your water heater does not have the capacity to meet the hot water demands of your home, you will most likely see condensation on the outside of your water tank. It’s important to note that while some condensation is totally natural, excessive amounts can be considered a source of concern. Condensation occurs as a result of the moisture in your tank being unable to dissipate owing to a lack of available space in your tank. The answer to this problem is straightforward. A tank that can provide enough hot water to meet the demands of your entire home is an excellent investment. Recent Posts by the Author

Why Your Water Heater is Leaking from the Top (How to Fix It)

  • Water leaking from the bottom of your water heater is something you definitely don’t want if your water heater is going to leak.
  • Although a water heater leaking from the top is not necessarily a good thing, it is better than a water heater that leaks from the bottom.
  • But, what is the source of the leak, and how can you stop it?
  • If you don’t take care of the leak right away, you’re likely to have more issues in the future, like electrical shorts in your heater and water damage to everything that is in the surrounding proximity.
  • And don’t assume that just because your water heater is leaking that you won’t have to replace the entire unit – it may be as easy as a simple repair.
  1. The good news is that if you find a leak early enough, it is nearly always possible to repair it.
  2. Water follows the least amount of resistance, which means that any water entering the tank from the top will flow down the side of the tank, causing electrical shorts and other water damage issues.
  3. This is why you should contact a professional as soon as you see a problem.
  4. In this article, we’ll take a look at some of the most common causes why your water heater is leaking from the top.

Common trouble areas

1) Loose fittings

  • Take a detailed look at the water intake and outflow fittings for leaks.
  • This is a frequent spot where water leaks, and you’ll typically notice the leak at the point where the fittings meet the water heater, as shown in the illustration.
  • You can try to tighten the fittings with a wrench if you have one.
  • This may entirely halt the leak, so resolving your problem..
  • Furthermore, rusting is not unheard of in this environment.
  1. The most effective way to deal with corrosion is to replace the fittings.
  2. This is also a simple procedure unless your fittings are made of copper, in which case they must be connected together using solder, which is nearly always a job for a professional plumber to do.

2) Faulty inlet/outlet valve

  • In the event that you notice water accumulating on the top of your unit, this is a solid indication that your input or outlet pipe is leaking.
  • In most cases, there will only be a loose fitting around the pipe, in which case you will only need to tighten the bolts that attach the handle to it.
  • Alternatively, if after tightening the nut you discover that the valve continues to leak, it is likely that the valve itself has failed entirely and must be replaced.

3) T&P valve

  • The temperature and pressure relief valve (T&P) is sometimes found on the top of the water heater tank, but that is not always the case.
  • This is a safety device that is activated if there is an excessive amount of pressure inside the tank.
  • The release of steam will allow the pressure to return to normal after it has been activated.
  • It is necessary to remove the valve and replace it with a new one if water is leaking from the threads of the valve.
  • You should begin by cutting off the water supply to the unit and draining it until it is below the water level of the valve.
  1. If you are confident in your ability to solve this problem, you should proceed to step 2.
  2. You’ll need to let some air into the tank, so turn on a nearby hot water valve.
  3. To remove the valve, use your channel lock tool to unscrew it.
  4. Give your valve and tank a thorough check to see if there is any corrosion present.
  5. Whenever you notice signs of rust in your unit, it’s time to replace it completely.
  • As long as your tank is modern, there should be no rust and no need to replace the tank; however, you will need to cover the threads of your T&P valve in Teflon tape and reinstall it on your unit to prevent corrosion from occurring.

Other issues

  • If your hot water heater is electric, it relies on up to two heating elements to heat the water before it is released into the system.
  • The heating components are extended into the tank and come into touch with the liquid inside.
  • Gaskets are fitted at the point of entrance to prevent leaks from occurring.
  • These gaskets, on the other hand, might become faulty, resulting in leakage.
  • A cover plate and maybe some insulation must be removed in order to obtain access to the gasket.
  1. Before anything else, cut off the electricity to the heater and the water supply to the heater.
  2. Before you can replace the element gasket, you must first drain the tank completely.
  3. Whether your hot water heater is leaking from the top or from anyplace else on the unit, Old World Plumbing will get to the bottom of the issue and get you back up and running in no time.

Should a Leaking Hot Water Heater Be Repaired or Replaced?

  • A leak does not always spell the end of a hot water tank’s life.
  • In certain cases, you may be able to repair the leak before having to dispose of the tank completely.
  • The position of the leak is sometimes clear, but a pool of water might sometimes appear some distance away from the source of the leak.
  • Determine the cause of the leak before making a decision on whether to repair the problem or replace the hot water heating system.


  • It is possible that a puddle on the floor is the consequence of condensation that collected on the outside of the storage tank.
  • Condensation happens when the majority of the water in the tank is below freezing.
  • This is more likely to occur during periods when hot water use in the home is very high.
  • Condensation is caused by the cold tank interacting with the warmer air inside the house.
  • The water then drops from the tank and onto the floor, giving the impression that the tank is leaking.
  1. Make an effort to evenly distribute hot water needs around the family so that less than half of the tank is filled with cold water at any given moment.


  • In most cases, a hot water heater is connected to two pipes: one for the cold water supply line and another for the hot water line.
  • The pipes are frequently equipped with elbow joints, which allow them to bend in the direction of the water heater.
  • Either of these water lines has the potential to leak, especially around the junctions.
  • If water is sprayed out of a fitting or pipe, the issue is obvious to see.
  • A leaking pipe or joint is less obvious than a dripping joint.
  1. To prevent leaks, tighten any loose fitting joints.
  2. If this does not resolve the problem, switch off the water supply and the electricity, and then separate the fittings from the pipes.
  3. Allow for a cooling down of the temperature of the hot water pipes before working on them.
  4. Plumber’s tape should be applied to the threaded end of each fitting before reconnecting the joints.


  • Heat is generated by one or two heating elements in electric hot water heaters in order to warm the water.
  • Gaskets are used to prevent leakage since the elements protrude into the tank and must be sealed.
  • Depending on how worn or broken the gaskets get to the point of leaking, water may pool beneath the tank.
