I suffer from allergic asthma not nice at all and this is a huge issue for me, water leaking from your heater can have health issue. Wet or dampen areas can grow mold that creates allergic reactions this affects asthma suffers just like my-self. Mold and mildew spores are harmful and can even result in severe illness this has shown in results from the EPA – damp and Mold in the house. Water heater leaks do not disappear or vanish as time progresses this will simply become worse, so my best advise is to resolve this issue and fast and take care of the issue.

Your First steps!

  • Determine whether the water heater really is the course.
  • Turn off the power to the water heater
  • Turn off the supply of water to your tank
  • Determine the location of the leak

Step 1: Is the water heater the real culprit of your leak?
It’s not always the case that a tiny drizzle of water at the bottom of your water heater essentially is responsible for a serious water heater leak. There can be a number of issues along with water pipes, appliances normally located nearby can develop condensation, and then it will soon gather and also fall to the main floor specifically when in the basement or during the rainy season. Below are the most common water heater leaks are;

  1. Worn Pipe fittings
  2. Damaged and worn heating element
  3. Drain valve leak
  4. Pressure relief valve blocked
  5. Water tank corrosion

Heater system drainpipes, Furnace drain lines and various other plumbing issues could can be a source of the water leak. If you do find water under the water heater, wipe it and find where it has come from with simple and straightforward observation of your water heater tank and pipes. Inspect as much of your water heater as possible as well as its plumbing installations for obvious indications of damages or breaks for a leak to appear. If nothing appears to be wrong, inspect various other close-by appliances or water pipes. Water consistently obeys the regulations of gravitational force, so pay attention to everything you can even above, specifically plumbing and water pipes in the surrounding appliances.

Even if not a single drip of water is discovered, lay down a kitchen paper or a newspaper over the spot that was wet return to assess it every hour. A day after check if the issue has not appeared, it’s most probably not a problem to be disturbed about. If, on the other hand, water does turn up once more and you can not find any other water leaks, a water heater leaking most probably what your problem is.

Step 2: Shut down the electric to your main water heater
When you have identified that the water heater does have a leak, you must insure the you shut down the power at the mains. With electric water heaters find the circuit breaker, turn off the circuit breaker.

  • Electric water heaters you will need to find your circuit breaker and turn off the correct switch
  • Gas water heaters turn the gas supply valve off

Electric and water are a dangerous mix, so it’s crucial you turn off any live electric before going forwards. Using other types of water heaters like a natural gas water heater? then you have another option? more thank likely have a simple on/off power switch. I personally like to stay clear of shutting the gas off valve, most of the valves are and can be difficult to turn on and tend to fail often, leave these as they are.

Step 3: Shut off the main water supply to your tank or home.

WARNING: Water from within your heater tank generally is set to a factory-setting of 125° F, this will give you first degree burn. When turned the up highest temperature level. Always take safety measures to prevent coming in to contact with hot water.

If you have a considerable and evident amount of water leak, Shut down the main water supply remember that turning the supply of water is the best way to carry out maintenance. Almost all water heaters do have a plug valve located on top by law this will allow you to turn off the main water supply.

To turn off the main water supply you should have one of two a gate valve or a ball valve, gate valves consist of wheels or knobs and required turning clockwise to close. Ball valves have handles and need to be turned 90 degrees to close.

You will need to close the supply of water using this valve , you can either turn it clockwise or pull it down depending on your water valve style but ensure your close it completely. Insure there are no hot water pipes or fixtures near while you reach out to this water valve as you will incur a serious burn.

Locate Water Shut-Off Valve, Pressure Release Valve & Water Drain

If there is a major leak and it is not possible to reach out to the main supply of water try to find the primary shut-off water tap form the main of the house this sometimes can be outside. Shutting the main water supply off ought to decrease and might stop the water leak but this all depends where the water leak source is. If the leak is not huge, leave your water supply to your home on this will help support in locating the leak.

Step 4: Find the leak Location
There are issues that lead to a hot water heater leaking there are a few simple procedures to conduct an easy assessment. An appropriate diagnosis even before you call a water heater professional can make for a less complicated situation problem. Lets take a look below at some of the most common reasons you may have the leak.

  • Heater drain valve: Inspect the drain valve and do it well! It’s situated near the base of your water tank. Make certain that it is closed entirely, also check the entry point to the tank should be watertight leaks from here are not critical issues and are easily fixed.
  • The hot and cold water outlet and inlet connectors: This is a simple but annoying issue to fix. At the top insure you examine all the inlets and the water pipe links to the main water heater. Leaks here may need a simple tightening the connection.
  • The lowest part of a hot water tank: Due to the fact that the tank is rolled up within insulation then covered in a light skin see photo above, a leak inside wont be apparent from the out-side of your tank. If you think there is an interior leak then usually the water probably will be released from the base of the tank. Almost all water heater leaks arrive from the water unit tanks, these leaks are usually brought on about with age. The only solution for this situation is to have it replaced when possible.
  • Pressure relief and Temperature valves: Yet this is just darn annoying but each water heater has a pressure and temperature relief valve situated on the side of the tank this usually had an extra pipe, this pipe usually runs down to the base of the floor. This valve is in place to make sure that if water is warmed up to extreme temperatures, or there is an increased pressure within the tank, the valve can then release water out from the water tank releasing that extra tension. Water heater leaking from side needs to be inspected usually at the top, check for watertight sealing. Evaluate the valve as this can be the root of many of these types of leaks, water will definitely be moving down the pipe secured to it. This indicates that valve is defiantly damaged, or it is getting the job done properly and excessive pressure from within the water tank pushing it to open. Leaks from here are generally a pain especially for me but they are fixable.

Water heater leaking from the Pressure and Temperature relief valve?

Below we look deeper into leaks from the top and bottom of your water heater read my tips and tricks on solving most leaking issues.

A simple leak is coming from the T&P relief valve or also known as the T&P valve can be triggered by too much compression within the water tank or heating up too much. This stress on the temperature and pressure valve will continue to trigger water to leak. To find out if the main cause to the leak, scale down the temperature by reducing the thermostat. Turn on the water then your gas/power back and monitor it for some time. Is the problem persists,close the whole thing off straight away.

If you establish substantial overheating or even a deal high pressure is not creating the issue, then you could have a defective valve. Use a container or bucket beneath the discharge pipe and then open your tanks temperature and pressure valve by opening out the tab so it’s facing right out. By opening this you will rinse the water out and take out any blockages that lead to your problem. If after washing the valve and you still have some leakage I do recommend that you remove and replace the T&P valve.

Having troubles with hot water tank leaking from the bottom? Before upgrading the temperature and pressure valve you’ll have to empty the hot water tank completely of water. Not familiar with the best ways to carry this out, I will have a in-depth article on maintaining a water heater soon: Simply just make sure this is under the valve and open your main valve then there is absolutely no water emerges then you are OK.

As soon as your warm water tank is emptied, head to your kitchen sink or bath tub open your tap to permit air inside the tank. Take hold of the temperature and pressure valve with channel locks then turn it very slowly counter-clockwise so till it has come off. Then with a brand-new valve, roll up the valves threads with a few wraps of Teflon strip (I highly recommend you do this) it will really help seal off it against future internal leaks. Ensure you wrap this tape around the threads properly right in to the notches. is completed, screw the brand-new valve onto the heater until safely in position.

Right after you can switch on the water source to fill up the tank with pure water. Don’t turn the main power to your water heater back up after you have ensured your tank is entirely full. Check your kitchen or bath tub tap you recently opened the second water is showing at normal speed from your taps you have then recognized that the water tank is full with water, you can then start to turn the electricity back on.

Be sure to connect a discharge tube to your brand-new temperature and pressure valve. Doing this assures that any water released from the valve drops to the ground level.

Still have concerns about how you can remove and replace the temperature and pressure valve? watch this video below to help:

Possible pressure and temperature leak issues: Water leaks from temperature and pressure valve then you will need to replace the valve refer to the information as described above. Look for any decay or deterioration if any type of oxidation or deterioration your water heater needs to be changed. Maybe your water heater tank seems healthy, but what would be good practice is to wrap the valve’s threads in a few strips of Teflon tape then screw it sealed to how it was and ensure a secure seal from any leakages. Monitor your water heater over time and check once again if this has dealt with the problem.

One more reason for leaks come from the main Temp&Pressure valve can be due to backlog around the primary shutoff point or even internal high water pressure. If you replaced your temperature and pressure valve and notice no other visible signs of erosion within the valve and noticed no sings of improvements you’ll need to have a certified plumber to determine and deal with this.

Warning: The T&P valve is a very important safety feature changing this with no experience can lead it to explode unexpectedly. modifying the T&P will also defect any current warranties you currently have .

A Water Heater Leaking from Top: Best way to fix it

Take a good look into these pipes, particularly at the point where they link to the water heater and all other fittings. If the trouble is only a loosened connection you could just need to tighten up using a pipe wrench.

If the pipe has broken or you discover any erosion then the issue may be more severe and you really should call an expert plumber to handle it as they will replace a section of the damaged pipe..

# 2: Your Temperature and Pressure Relief Valve actually isn’t water tight
If you discover water leaking down the side of your tank then inspect the Temperature and Pressure, positioned on the side of the tank. Have a good feel and look over the edges to see if there is any sort of water leaking out. If water is leaking from the threads of your T&P valve then you’ll need to have it replaced and examine it even more.

Empty the tank till the base of the valve (read more on the best way to Drain the Tank and Wash Out Sediment) then open a nearby faucet to allow air into the tank. Use a pair of channel locks to loosen the valve from the tank. Investigate at the opening where the valve originated from and look for any decay or wear on the tank. If there is no obvious decay of deterioration wrap the threads of the valve in Teflon tape to assist waterproof the valve more effectively and tighten it back into the tank.

# 1: Temperature and pressure relief valve can cause this Leaking
The water heater pressure relief valve is created to deliver water around you home if there where to be excessive pressure within the internal tank, other reasons can occur from water getting extremely warm then you are exposed to leaks. These valves are prepared with an outpouring pipe to the floor. The prime feature of this pipe is to allow over flow water to flow out of the tank then to the ground, instead of an inwards direction where maybe damaging your tank. If you have water at the base of your leak hot water tank check with the discharge pipe for any dampness. If you discover some dampness, the issue is probably the temperature and pressure valve. Often there is a bit too much pressure from within the water tank you would also need to check the T&P valve as this can be week and will need replacing. This is replaceable and can be done your self by changing the valve or if this is too advanced for you should phone a plumber to manage the interior pressure problem.

Leaking temperature-pressure.
It is not typical for water to drop from the temperature-pressure (TP), which is designed to discharge water when it detects extra pressure. Extra pressure can possibly be due to the temperature being set too high.

In many cases, the TP relief valve in itself may be damaged if it is, it will have to be changed promptly. Consult with your owner’s manual for guidelines to carry out and see the best way to Replace a Water Heater Pressure-Relief Valve, or consult with a plumber who deals with water heaters. A working TP valve is certainly necessary to avoid severe buildup of steam that could cause a water heater tank to erupt.

Drips from water heater drain valve.
You can handle some water leaks generally by stiffening the drain valve. If the valve itself is malfunctioning, you will require removing and replacing it.

Condensation drips.
In many instances, condensation can emerge when cold water saturates the tank and after that the condensation leaks downward. This issue usually shows up when the tank filled up or during a nippy season but then this problem eventually disappears when the water has had the opportunity to warm, this typically suggests condensation and you should not be alarmed.

On gas water heaters.
Condensation will also come from the air vent. Look for barriers in the vent. If you identify any, shut down the water heater and clean the vent. If the problem lingers, get in touch with a plumber or water heater repair professional.

Leaks from water heater’s Gasket.
With certain electrical water heaters, leaks can come from gaskets. Shut off the electric power, turn off your water supply, and empty all the water the heater before removing and replacing the gasket as detailed mentioned earlier. Also, before flipping the power back on, ensure to activate the supply of water to the heater and run warm water into your home to discharge air that has been retained in the water heater tank. Failure to do so could quite possibly ruin your heating element.

# 2: Leak from the drain valve

This should really eliminate any dirt. If shortly after cleansing the valve and you still have a leak you will need a full replacement.

Replacing the drain valve, empty the tank entirely, follow the steps described earlier for replacing the temperature and pressure valve.

Suggestion: In contrast to the temperature and pressure valve, the heater drain valve is not a safety and security feature. If you are uncertain about replacing the valve your own self or really don’t have time to obtain to it straightaway, simply purchase a brass garden hose end cap you will need to screw this onto the valve threads. This should really help to stop the leak.

# 3: Leak from the tank
The majority of leaks stem from the tank. This suggests an interior problem with your water tank. Some of its elements have sprung a leak which in turn has leaked the tank and is gradually leaking outside.

Generally, the reason for this is debris build-up inside of your tank. If this sediment is left enough time it will start to break and corrode the tank, ultimately resulting in a leak.
