A water heater is one of the most important pieces of equipment in any home, but they also tend to be some of the most overlooked appliances. It’s easy to put off repairs on smaller appliances like washing machines or dryers, but a broken water heater can have serious consequences if not addressed quickly. Luckily, most water heaters last between eight and 15 years, so it’s not something you need to think about replacing every couple years like you do with other appliances. However, there are signs that your water heater is beginning to break down. These might be obvious to you, but it’s important to inform any potential new tenants about these things ahead of time so they aren’t caught off guard when they move in. A broken water heater is inconvenient at best, but it can also lead to serious damage and health risks in the long run if left unaddressed. Here are some signs that might mean it’s time for a new water heater in your home:

You begin to experience frequent water outages.

If your water supply begins to run dry more frequently than usual, it could be an indication that your water heater is beginning to break down. The water heater keeps the water supply hot and flowing by using electricity to warm up the water inside it. If your water heater is beginning to break down, it might not be able to keep the water flowing at a consistent temperature. This can cause your water to run cold even when the flow of water coming into your home is uninterrupted. If a water outage isn’t inconvenient enough, it could also be a sign that your water supply has been contaminated. This is especially true if your water is coming out of the faucet a murky color or smell.

Your water bill is unusually high.

Water bills will always vary from one month to the next, but if your water bill suddenly spikes, it could be an indication that your water heater needs replacing. As mentioned above, water heaters typically last between eight and 15 years, but some older models are more susceptible to high water bills. If your water bill is unusually high, consider having it checked by a water meter reader. They can tell you what’s going on with your water supply and help you figure out the best course of action going forward.

Your neighbours experience a drop in water pressure.

If your neighbours begin to experience a drop in water pressure, this could be an indication that your water heater is experiencing an issue and needs servicing. Depending on the type of water pressure regulator you have installed, this could be due to the fact that your water heater is running out of hot water, or it could be a sign that your regulator is broken. If this happens, it’s important to inform your neighbours right away so they can turn the water supply back on as soon as possible.

You experience water-cooler-like water at the end of the day.

If your water has a distinctively cool and wet feeling to it when you turn off the water supply at the end of the day, you might have a broken water heater. This is because most water heaters don’t have an automatic shut-off feature. This means that the water supply will continue to run until someone turns it off manually. If your water supply has been running all day and you have a family or house full of kids, this could lead to serious health risks. The best thing to do is to install an automatic water shut-off device. This can be installed as part of installing a new water heater, or you can purchase a stand-alone model.

Water is coming out of the faucet black and murky.

If you begin to notice that your water is coming out of the faucet black and murky, it could be an indication that your water supply has been contaminated. This is particularly true if your water is coming out of the faucet black. Black water is typically a sign that your water supply has been polluted with sewage. This can be caused by a variety of issues, including a faulty water heater that isn’t keeping the water heated consistently.To be sure, you should have your water tested to make sure it’s safe to drink. This can be done at a variety of locations or online.

Summing up

A water heater is one of the most important appliances in any home. It’s important to remember to properly maintain and repair appliances to keep them running smoothly. By keeping an eye out for signs that a water heater may be beginning to break down, you can address the problem before it escalates. Before beginning repairs, make sure to research the best way to approach the job. This will help ensure that your water heater is fixed properly and safely.

Frequently Asked Question

While you technically can install a hot water heater yourself as a homeowner, the likelihood that this is a good or safe idea is very slim. Trust the professionals with your hot water heater installation to make sure it's done correctly. You wouldn't want to cause yourself or your family any harm.
The higher cost is a result of a more labor-intensive set-up, as new gas and water lines are required for installation. For a new tankless water heater, new electric wiring will need to be installed.
Turn off all water supplies in the house. Turn on all the hot water faucets in the house in order to drain what is left in the existing hot water heater. Then, disconnect the water line that connects the water heater to the rest of the house. There is often a connection on a hose that you can simply unscrew.
  • Your older water heater is getting up there in age
  • It's making strange noises
  • You're getting rusty water out of the tap
  • Your hot water doesn't last as long as it used to
  • There are water puddles around the unit
120 degrees Fahrenheit is the safety recommendation against scalding, but 140° is the common default setting. Most experts agree that anything below 120 degrees creates a risk for bacteria to develop inside your water heater from stagnant water, such as legionella that causes Legionnaire's disease.
Turn up the thermostat on the hot water heater. One of the easiest ways to make a hot shower last longer is by using less hot water while it's at a higher temperature. To do this, turn up the temperature on the thermostat that's attached to the hot water heater tank. (Not the thermostat on the wall.)
Sediment buildup shortens the life of your water heater and adds to your energy bill by reducing its efficiency. Draining two or three gallons of water is usually enough to flush out sediments, but always let the water flow until you no longer see particles in the bucket. Regular water heater maintenance will always extend its lifespan.
These heaters can be fueled by electricity, gas, or liquid propane and installed in many areas of your home. The national average cost to replace a 50-gallon water heater is $1,100 to $2,800, with most people paying around $1,800 for a direct replacement of a 50-gallon gas hot water heater using the same model.
  • You're overusing hot water.
  • The water heater tank size is too small for your household.
  • Your hot water heater is tankless.
  • Sediment or minerals have built up in your water heating system.
Soft water can actually corrode the water heater anode faster. When the anode wears down, the corrosive elements will move on to the tank. So if left alone, a water softener system can actually shorten the lifespan of a water heater.
