Like all appliances, water heaters have a limited service life. Knowing how long you can expect your water heater to last and when you need to replace it can help you avoid a catastrophic water heater failure. These answers to frequently asked questions can help you take care of your unit.
How Long Do Water Heaters Last?
Most water heaters last about 8 to 12 years if properly maintained. Homeowners who keep their water heater longer than this time run the risk of a water heater failure that could result in a flood in the house.
What Can You Do to Make Your Water Heater Last Longer?
Most water heaters need minimal maintenance throughout the year. However, homeowners with hard water can extend the life of their water heater by installing a water softener. Water softeners can prevent scale buildup inside the water heater, thus helping to preserve the efficiency of the unit.
Inspecting your water heater on a regular basis can help as well. When inspecting your unit, look for signs of rust, corrosion, moisture damage, or water stains on or around the water heater. If you see any of these signs, contact a plumber right away.
Some homeowners protect and preserve their water heater by draining the sediment regularly from the bottom of the tank. Draining the sediment can prevent the water heater from working harder than necessary to do its job.
To do this task, turn off the power to the unit as well as the water supply to the tank. Then follow these steps:
- Turn on hot water in a bathroom or kitchen sink to prevent a vacuum from forming in the pipes.
- Hook a hose up to the spigot on the bottom of the tank.
- Open the spigot.
- Let the dirty hot water at the bottom of the tank drain into a bucket. Be careful at this stage because the water may be very hot.
- Empty the bucket periodically.
When the water runs clear, the tank has been drained of sediment. When the process is finished, turn off the spigot on the water heater, then turn on the cold water valve leading to the water heater to refill the tank. Once the tank is filled, turn off the hot water faucet in the house and restore power to the water heater tank.
The sediment should be drained on an annual or bi-annual basis. If the home has very hard water, it should be performed even more often.
Is Your Water Heater Nearing the End of Its Service Life?
If you're not sure how much life your water heater has left in it, there are some signs you can look for that it's nearing the end of its usefulness. Your water heater may develop a small leak or corrosion around the top edge of the tank. It may also lose efficiency or be unable to heat water as well as in the past.
How Can You Tell How Old Your Water Heater Is?
Many modern water heaters come with stickers that give the date that the water heater was manufactured. Some water heater manufacturers simply encode this information into the serial number. If you cannot find a sticker with the date on the water heater, look in the owner's manual to decode the serial number, or contact the manufacturer for help.
Is It Possible to Replace a Water Heater as a DIY Project?
Although a water heater may be replaced by a knowledgeable DIYer, it's best to contact a professional. Hooking up your water heater incorrectly could result in a flood or could even cause damage to the new tank.

When a water heater tank fails, the result can be disastrous. Depending on the location of the water heater in the home, tank failure can cause hundreds or thousands of dollars in damage. However, performing regular maintenance on your water heater can help you keep the heater in good condition and can even help catch water heater problems before they become serious.
Inspect the Water Heater Quarterly
Inspecting your water heater on a quarterly basis is a good way to catch problems before they damage the house. When inspecting your water heater, check for the following:
- Corrosion. Corrosion on the tank or around the pipes feeding into the tank could be a sign of an impending leak.
- Soot. Soot around the electrical parts of the water heater or in the location of the pilot light could be an indication of a short or a malfunction.
- Temperature. For many water heaters, the recommended temperature setting is 120 degrees Fahrenheit. If the temperature is higher than the manufacturer recommends, the water heater is forced to work harder than necessary to do its job. This can reduce the service life of your water heater. Check the temperature of the water heater with each inspection and make changes as necessary.
If you notice anything questionable about your water heater during the annual inspection, contact a plumbing expert for help. Your plumber can help you determine whether or not your water heater is in need of repair.
Flush the Water Heater
Sediment buildup happens naturally in tank water heaters and is especially common in homes with hard water. Sediment buildup can block the heating elements in the bottom of the tank, forcing the tank to work hard to heat the water.
Some homeowners might notice a popping noise in the bottom of their water heaters. This sound is an indication that the sediment in the bottom of the water heater is roiling and broiling when the water heater is turned on.
You can flush the water heater on an annual basis to help keep this sediment out of the bottom of the tank. To drain the sediment from your water heater, do the following:
- Turn off the cold water valve at the top of the tank.
- Cut the power to the appliance.
- Open up a hot-water faucet somewhere in the house to prevent a vacuum from forming in the pipes.
- Give the water in the tank time to cool. This step is technically optional, but homeowners who choose not to do this step must be very careful to avoid serious burns.
- Thread a hose onto the spigot located at the bottom of the water heater.
- Place the open end of the hose into a five-gallon bucket.
- Turn on the spigot at the bottom of the water heater.
- Fill the bucket with water until the water runs clear. You may need to fill the bucket more than once before the water is clear.
- Carefully dump the water from the bucket.
When the water coming out of the water heater is clear, the water heater has been fully drained of sediment. When the process is finished, close the spigot at the bottom of the water heater and turn on the cold water valve at the top of the tank.
When water begins to flow freely from faucets in the house once again, this is a sign that the water heater is full. Turn on the power to the water heater and turn off the hot-water faucets in the house.
