Don’t get left in cold water—you can take steps early and often
Your water heater inspection should happen every two months to catch leaks, corrosion, and performance issues before they turn into emergency repairs.
Water heater repairs cost $220 to $980 on average, while replacement ranges from $880 to $1,800 when your system reaches the end of its life.
Check your hot water supply daily, listen for unusual noises, and watch for temperature fluctuations to spot problems before they worsen.
Hiring a local water heater repair professional provides reliable support with pressure relief valve testing, anode rod inspection, and tank flushing to keep your system running smoothly.
If you’ve got hot water running, you’re likely not concerned about the water heater. After all, it works properly, so why should you worry about it? Unfortunately, that line of thinking can allow maintenance to slip by, causing your water heater to break unexpectedly. And unexpected breakdowns seem to happen at the worst times—something you don’t want to deal with.
Fortunately, inspecting your water heater can help keep it running smoothly. Luckily, there are some easy tasks that you can do yourself to give your water heater a checkup without breaking a sweat. We have a handy water heater inspection checklist that’ll guide you through what to look out for and what a professional would do during an inspection.
You should plan on inspecting your water heater every two months to avoid any major plumbing problems, such as leaks or burst pipes. However, you can do a quick inspection any time you enter the room to ensure that everything is in tip-top shape. Even more simply, you can do some of the inspection during your daily living tasks, like doing dishes or taking a shower.

Check your faucets for a supply of hot water.
Check the color of your water.
Listen for banging or unusual noises.
Check your faucets and shower for decreased hot water pressure.
Check for scorch marks on the base of the water heater.
Check for the proper ventilation of a gas water heater.
Confirm the drain pan is under the water heater and empty it if necessary.
Clear debris away from the water heater.
Check for signs of leaks, like water on the floor.
Check the water bill to see if there is a large increase in utility cost without an explanation.
To prevent carbon monoxide exposure from a water heater, make sure it is properly ventilated. You should also have it inspected and cleaned every year and install a carbon monoxide detector nearby. If you smell gas—which can mimic the scent of rotten eggs—evacuate immediately and call your gas company.

Inspecting your water heater yourself is a great way to notice the first sign of trouble, but sometimes it’s best to call in a water heater professional to take a deeper look. A pro can help diagnose any problems as they appear but can also inspect other facets of the water heater that you might not want to do yourself for safety reasons.
Your local water heater repair contractor will do the following during an inspection:
Perform visual inspection for leaks, damage, or corrosion.
Test the pressure relief valve (TPR valve).
Check for hidden leaks that are not easily visible.
Flush the tank.
Inspect the anode rod.
Check the gas line for gas heaters.
Examine the venting system for gas heaters.
Test the heating element for electric heaters.
Check water quality for proper PH levels.
During this inspection, the plumber will recommend any repairs that may be necessary or might suggest a new water heater altogether if yours is aged and starting to wear. It’s recommended to have a professional inspect your water heater once per year to ensure proper operation.
Beyond keeping up with your DIY and professional water heater inspections, there are other maintenance tips that you can use to extend the life of your water heater. Some of these will be done by your water heater pro, but if you feel up to the task, you can do these yourself to make sure you don’t run out of hot water any time soon:
Turn your water heater to vacation mode (if applicable) to allow it to run in an energy-saving mode if you’ll be away for a vacation. Likewise, you can turn down the water heater's temperature during this time.
Insulate your tank by using thermal wraps to reduce energy consumption. This will help keep the heat in the tank, causing the water to stay hot longer.
Flush your water heater every six months to clear any sediment from the bottom.
Inspect the anode rod for signs of rust or corrosion.
Check your temperature control setting; if an adjustment is made and you still don’t have hot enough water, this could indicate a sensor or regulator issue.
Taking precautions, along with inspecting your water heater for proper operation, will help keep your showers hot and your dishes clean. It’ll also help eliminate the need for a frantic call to a water heater pro when there’s no hot water.
There are many signs, both big and small, that indicate your water heater is starting to break. Noticing these signs right away is an important step in preventing the loss of hot water altogether. Some signs of common water heater problems you want to look out for include:
Tapping or knocking sounds
Lack of hot water
Temperature fluctuations
Leaks around the water heater
Odor in the water
Rust or brown-colored hot water
In addition to the above noticeable signs, you want to also be aware of your water heater’s age. If it’s older than 10 years, you’ll want to consider replacing it soon, especially if it’s showing any of the above signs. Water heaters normally last between 6 and 12 years unless they’re tankless, which can last around 20 years. When it reaches double digits, it’s not unlikely that you’ll start to have trouble with it sooner than later.
A water heater inspection is a job best handled by a water heater installation and repair pro near you. In-depth water heater inspections are not normally included in a home inspection, so instead of hiring a home inspector, you’ll want a pro who specializes in water heaters. If your water heater needs to be repaired, a water heater specialist will often be able to perform minor repairs on the spot. Water heater repair costs an average of $220 to $980, depending on the type of repair.
Your water heater inspection may reveal that it’s time for a replacement. On average, replacing a water heater costs between $880 and $1800. It’s better to plan a replacement before your current heater has a catastrophic failure so you don’t find yourself without hot water for an extended period of time.
As usual with ECO, tech Jordan was outstanding, very professional, very knowledgeable, and very thorough with repairs made to tankless water heaters. Very highly recommend ECO!!!
Did a great job replacing the ice maker and water regulator on my refrigerator. He was quick and thorough, very friendly and professional. If I needed a heart transplant I'd want him to do it!!!
We had a gutter blockage that was causing water to sheet down the side of the house and ultimately it started to come in at a window (need mortar people next). Called around 7:30am, and he responded by 8am. He was able to come out the same morning and do a look over and clean out. He also...
Scott checked our large crawl space for mold and water infiltration and recommended a viable solution. The crew was efficient and they cleaned up well after the job. The job was expensive but I am confident that I won't have to deal with the problem again. Highly recommend.
Chaz, the owner, was very responsive and he communicated with us throughout the entire process. The overall cost was in the middle compared to the three estimates we received. The installation crew was very professional. Chaz was considerate enough to send a crew back to our home to repair...
They were the most through inspecting the water system in my house. Even going the extra mile to get the water professionally tested for contamination.
It went very well. The drain is absorbing all the access water. I had other estimates a year earlier and Hughes was right on. I will use them, again.
We had water in our basement and Roto Rooter was original contact to evaluate the situation. We were informed that our sewer main was fractured and needed repair. We received their estimate and then looked for counter offers. Ohio Basement Authority came with the best quote for the work. Once...
Carpets came out very well, as usual (we have used them before). The price was right and the service was great. When we had an issue with water spots on our hardwood stairs from dripping equipment, they made it right immediately, and were very professional about it. Great company to work...
My painting job was a tricky one, with 18' walls and large ducts to work around near the top, in a downtown condo with its associated parking and unloading challenges. Brad and his crew did a great job in a short amount of time. My walls look great, with even paint and clean lines,...
