Why is my water heater leaking from the bottom? Property owners dread moments like this, brace themselves, and start to mentally check their bank account balances. Immediate action may be needed to protect your home. Regardless of what is causing the leak, priority one is protecting you and your home. For an electric water heater , look for the breaker on the main electrical panel.
Hopefully, this is labeled. Turn this to the OFF position. Usually located toward the bottom of the heater, turn this into the OFF position. The water heater will just keep refilling itself unless you stop the supply. This means an endless amount of water will continue to run until the supply is off. Exactly why we recommend turning off the water to your home when going on vacation! There should be a lever or valve toward the top of the water heater.
This is the water supply inlet and is exactly what it sounds like — how water gets into the heater. It is not strictly necessary to turn off the gas on a gas water heater. To turn the gas off, look for a smaller lever towards the bottom of the heater. The handle might be red, blue, or yellow. These steps keep the water from flowing in your house like the rivers of Egypt. However, you still have a tank full of water.
If the leak is very aggressive and already filling the overflow pan, tart bleeding the tank of remaining water. Look for the drain valve at the bottom of the tank. It will look similar to the hose bib on the side of your house.
This may actually be where the leak is coming from, but should still function for this purpose. This will keep the remaining gallons in your water heater from leaking all over the area where the water heater is stored. The tank will eventually drain. Now that the leak is under control and there is less concern about damage to your home, we can start to figure out where this water heater leak is coming from.
Before you call a licensed plumber , try to self-diagnose the repair. The steps below will help estimate the severity of the issue and give you something to talk about with your plumber.
Bad news first. If the water heater is leaking from the bottom of the tank itself there is no getting around a water heater replacement. The tank has rusted out, likely due to sediment build-up.
There is no way to repair the tank without replacing the entire thing. The leak will start out small — likely a pinhead but tank pressure will force that leak to get bigger and bigger.
If a tank leak is your issue, immediately turn off the water heater supply and call a licensed plumber. Every tank-style water heater has a drain valve at the bottom. These are intended for use during maintenance and replacement of the water heater.
Sometimes, the drain valve can become loose or fail. If the drain valve is leaking, try tightening it by hand first. It is possible that the valve was just knocked loose.
Never use a tool to close this valve. It is designed to close by hand. Continued dripping, once tightly closed, indicates something is wrong. You may make a bad situation worse by over-tightening and could even break the valve off completely!
Very handy folks may feel comfortable replacing the drain valve on their own. Once the tank is drained, a little Teflon tape , a wrench, and elbow grease is all it takes. The valve itself is usually towards the top of the water heater, but a tube may be attached running to the bottom pan of the heater. This neat little piece of technology is actually what keeps your water heater from shooting off like a rocket when things get too hot.
So, we obviously want that to stay in good working order. It could also mean that the pressure in your house is too high a common problem here in the Upstate or it might mean the temperature is too high on the heater itself. You never want to block, close, or otherwise disable a Temperature and Pressure Valve for reasons listed above. They can go off without warning and release very hot water. If you do not, checking your water pressure is a good start.
A water pressure gauge can be purchased inexpensively. Water pressure higher than 75 PSI is cause for concern. For the overall health of your plumbing, this should be addressed by installing or fixing a PRV.
Next, check is the temperature settings on your water heater. Too high or too low, each come with a unique set of risks. Too high is an obvious safety concern. Scalding can happen quickly and is extremely risky for small children and the elderly. Sometimes the configuration of your plumbing requires a slightly higher temperature, due to thermal loss.
Meaning that water cools down quickly on the way to the fixtures, requiring a higher starting temperature. This is very dangerous and can lead to the development of Legionnaires Disease in your water.
Very dangerous and not something you want to tangle with. Trust us. You will want it replaced immediately. Luckily this is a minor repair typically completed in about an hour.
The parts cost is also minimal. All-in-all, not a bad ordeal. Eventually, age will ravage your water heater one way or another.
The life expectancy of a water heater is typically seven — twelve years. Keeping up with regular maintenance on your heater is a good way to ensure you get the longest use of the appliance. Keep in mind that a yearly draining of your water heater and checking of the anode rod can extend the life of your water heater in several ways, not the least of which is preventing the rust which causes tanks to fail.
This is a fairly simple process, which includes unscrewing the anode rod from the top of the tank. Check the level of build-up on that rod. Replace it once it starts looking like an artifact from the Titanic.
Draining the heater is as simple as attaching a hose to the drain valve or placing a bucket underneath the open valve. Watch the water and turn off the drain valve once it is running clear. The purpose of a yearly draining is just to get that sediment out, which all sits in the bottom of the tank. Sediment and mineral deposit build-up actually take up space in your water heater meaning that your gallon tank might actually only have 20 gallons of water in it!
Other than regular water heater tank maintenance , water pressure and tank temperature are the two things to keep an eye on. Just like when you drive a car aggressively, it may shorten the lifespan of the product. A drain valve is relatively easy to fix on your own. While it is possible to repair on your own, there may be serious consequences to a bad repair.
Replacing an entire water heater is always something that a licensed plumber should complete. There are very real safety and property concerns that make a DIY job risky.

Water heater bottom. The temperature and pressure and relief valve
To help other readers we've copied your question and posted a longer reply at the Debris article cited just above - Editor. The dip tube is a tube that extends from the inlet to the bottom of the water heater to prevent the incoming cold water from mixing with the hot water causing a rapid reduction in temperature of the water going out of the tank. This was also the subject of a class action lawsuit for which the claims period is now over.
AO Smith was one of the companies and the manufacture date is in the middle of the defect period I have no doubt your dip tube is bad. That's also where hot water exits to the building - from the top of the tank at the hot connection. Now the whole water heater is "hot". When the water heater is in use cold water is entering at the tank bottom out of the end of the dip tube but also somewhat mixing up water in the tank.
Smith water heaters has an excellent service handbook that explains these operating modes and instead of flip-flop they call it "non-simultaneous operation" of the electric water heater elements. It is possible to convert some flipflop electric water heaters to operate the two elements simultaneously but as AOS points out you can't do that if the total amperage draw exceeds the circuit and equipment rating say 40A. Watch out : setting any water heater to deliver temperatures above F can cause dangerous burns.
Smart repair people and owners use a neon tester or multimeter to absolutely confirm that electrical power has been turned off before ever touching electrical components. We removed the upper panel metal cover two screws , lifted off the styrofoam insulating cover, and revealed the water heater control in our photo at left.
Also located behind each panel is the actual upper or lower heating element. Our photo above right is the same location as we showed above, but we removed a plastic safety cover to show the electrical connections and other controls available here.
If setting the water temperature to a lower setting does not work there is a problem with the control and it probably needs replacement. I changed the element on my fathers boiler it only has a single top element The old one was set to max so that's how I set the replacement.
If you installed a mis-matched electric water heater element it may indeed be overheating. There is also a slight metallic smell in the water and slight odd taste. Can you help us determine what's going on. This water heater is set to its maximum output temperature, degF.
If water leaves a faucet at degF. Typical settings are to degF. Beware that any temperature above degF. Our two photos above are of the lower heating element on this electric water heater.
You can see from the burned and melted plastic that there was a problem with the lower heating element on this unit. But if you see this condition on an electric water heater whose history is unknown, do not assume that this is a current problem. On this water heater we replaced a burned-out bottom heating element several years ago, leaving the burned plastic cover and insulation cover on the unit.
Wiring details provided with these water heater controls are. The red reset button works for my electric hot water heater but after a few days I have to reset it again. I drained the water heater until it was clear, and I know both heating elements are working. No hot water at all, not even luke warm. Or just normal. Thank you for you help. My reset button light is very dimm and the water is not heater. I have replaced the upper element and the control board and the still no hot water and the reset light is dimm.
Water tank manufacturers do NOT want anyone to add insulation to the exterior their water tanks safety concerns and may even void the warranty if someone does so. To find the reset button on a water heater element if there is one you'd need to - turn off electrical power to the heater. Before replacing a water heater element I'd check to confirm that it is defective. Test and replace one or both bad heating elements - if they're bad.
Also, there was evidence that a short had occurred in lower element region as there were burn marks on or near cover or where there was an electrical malfunction, both elements have been replaced, and still no hot water, both elements appeared to be normal when removed.
I have an 80 solar water tank with electric backup, mixing valve, upper heating element only, PT valve and solar panels upper manifold air release valve.
Occasionally, the water reaches boiling and the PT and air valves do their job but the red element reset switch pops off too. This means going up into the attic.
Can I in any way disconnect the red reset switch? I presume this switch is not electrical but a bimetal strip mechanism, right? Watch out : I would never disconnect a safety device.
A combination of multiple errors could still lead to an overheated exploding water pressure tank - a catastrophe search InspectApedia for BLEVE to read what can happen.
I just wouldn't take a chance. How can I tell which water heater has burned out, the upper or the lower unit? Usually if the upper element has burned out you'll find that the quantity of hot water has not been reduced as much as you'll observe that the water provided by the heater is tepid.
And if the lower electric water heater element has burned out you'll find that the water supply may be plenty hot, but less in quantity. It's a good idea to purchase a water sensor alarm to alert you of any future leaks. Water sensors can save you a major headache, and for the price, they are an excellent investment.
If you notice water seeping from the base of the valve, you'll need to replace the drain valve. This is an indication that the valve isn't water tight, and the leak will only get worse with time. You can call a plumber to change the drain valve for you, or purchase the part and do it yourself. Step 3 will show you how. The majority of leaks come from the hot water tank itself. If the tank is leaking, there's an internal problem that's causing water to slowly leak out and pool at the bottom of the tank.
Usually, the root cause, is a build-up of sediment within the tank. When sediment isn't drained from the tank on a regular basis, it'll begin to cause the steel tank to crack and rust. Over time, a leak will eventually develop.
Flushing your water heater and checking the anode rod once a year will help prevent sediment build-up and add years of service life. Now that you've located the leak, the next step is to turn off the water and power to the water heater, this will help prevent further water damage. Refer to your emergency shutdown procedure sticker located on your water heater. If your water heater does not have this sticker, follow these steps:.

Why is my water heater leaking from the bottom? | Greenville Plumber, All Clear Plumbing
When it comes to water heaters, a little maintenance goes a long way. Learn how to spot the signs of water heater failure. Is your shower water lukewarm? Does it take a long time to get hot water from the tap?
As the water is heated usually by a gas or electric source , water minerals separate and settle at the bottom of the water storage tank. Over time, these mineral deposits build up in the tank and create a barrier between the burner and the water.
This means that less heat reaches the water — and your showers get colder! Eventually, the heater will fail — either leaking or ceasing to operate altogether. The result? A costly water bill caused by leaking and a heater that needs to be completely replaced! Schedule an annual flushing of your water tank.
Water heater noises are another common culprit of water heater failure. Hard water and mineral buildup are also to blame when it comes to water heater noises. The distinct popping water heater noise is caused by minerals forming a layer on the surface of the water heater. The sound is caused by pockets of air in the sediment layer boiling along with the water in your tank.
The best alternative is a replacement before the tank causes a costly leak. Does your water look cloudy? Do you detect a metallic scent — or even taste — in your tap water?
Murky water and funky-smelling water are both signs of a failing water heater. Mineral deposits travel out of the water heater, clouding up the hot water flowing from your taps.
A metallic odor and even taste can accompany these deposits. These mineral deposits can impact faucets, clogging elements that control the flow of water. Additionally, a cloudy orange or reddish color in water could mean your water heater tank or house pipes are rusty. If cloudy or rusty water bother you, you can filter water for a short-term fix. While it does not look appealing, the EPA reports that rust in water does not does not cause any immediate health concerns.
But once rust has reached your tank or pipes, the only solution is to replace them. Take a proactive approach to replacing tanks or pipes before corrosion causes a leak. There are two major symptoms to pay attention to when it comes to the pressure relief valve on your water heater.
Is your temperature and pressure relief TPR valve leaking? Or, does hot water not flow through the pipe when you test the valve? The TPR valve opens to release pressure buildup in the water heater when the temperature or the pressure get dangerously high, preventing a possible explosion. A buildup of mineral salt, rust, and corrosion can cause a TPR valve to freeze and fail to function. While rare, a failed safety relief valve can cause catastrophic damage.
If your water heater TPR valve malfunctions, water in the tank could exceed boiling point, expand into steam, and propel the tank like a rocket through multiple floors, reports the International Association of Certified Home Inspectors. This can cause both personal injury and extensive property damage. To test the TPR valve, raise and lower the test lever several times so it lifts the brass stem that the valve is fastened to.
Hot water should rush out of the end of the drainpipe. If no water flows through the pipe or you get just a trickle, consult a plumber to replace the valve and ensure that debris or equipment malfunction is not causing a malfunction. Temperature and pressure relief valves should be professionally tested once a year to assure they are working properly.
If you notice a leak, or if the valve does not respond to your test, call a plumber immediately. Is water pooling beneath your tank? Corrosion within the water tank can lead to fractures and cracks. Leaking hot water from the tank is an obvious sign of trouble and requires replacement of the water heater. A leaking water heater can flood your entire home if not replaced immediately.
Remember, if the leak is from the TPR valve, it could be caused by excessive pressure inside the tank or overheating. If the tank leak is severe, turn of the water supply at your water shut-off valve.
While this is only a temporary fix, it will at least prevent a basement flood and not to mention, gallons of wasted water. The water heater tank will have to be replaced. The good news?
