If your water heater is having any issues, such as leaking or taking longer than expected to come to the right temperature, it’s important to get it fixed as soon as possible. Broken or malfunctioning water heaters can be dangerous in any home, but especially when you have young children or pets. Unaddressed issues with your water heater can also lead to much higher utility bills and more wear and tear on your home’s plumbing. If you notice any of these signs in your water heater, it’s time for a professional inspection and possible repair. If you notice any of these signs, contact your local plumber immediately so that you can avoid a dangerous situation. And if your water heater is new or less than five years old, read on for more information on when to replace it in the future.

Leaking Water Heater

The most obvious sign that your water heater is having problems is a significant amount of leaking in and around the area where it is installed. This could mean that a valve has come loose, or that debris is blocking the flow of water into the tank. The leaking water can cause extensive water damage to your home, which might require expensive repairs. It’s important to get water out of the area as quickly as possible, as it can lead to mold and mildew growth. If you notice a lot of water around your water heater, get it out of the house as quickly as possible with a wet towel; it might help to remove as much water as possible before calling a plumber.

Water doesn’t get hot enough

Another common sign of a broken water heater is that the tank doesn’t get as hot as it should. The temperature should rise above 170 degrees Fahrenheit, which is the point at which water is considered hot enough for use. If the water isn’t getting hot enough, it can be a sign of an issue with the thermostat, but it could also mean that the water is being shut off before it gets hot enough.

No hot water at all

Another obvious sign that your water heater is broken is if you have no hot water at all. This could mean that the water is not coming in contact with the heating elements, or that a valve is not fully open. It could also mean that the tank is completely empty, and that you will be receiving a service call very soon.

The water is black, orange, or green

If you have a water softener or water filter in your home, you might notice that your water is turning a strange color. This could mean that the water is not being heated enough to remove chemicals from your water supply, which is a serious issue that should be addressed immediately.

Bubbling sounds or leaks

Finally, if you hear bubbling sounds coming from your water heater, or if you notice a significant amount of water leaking from it, it’s best to call a plumber as soon as possible.

Bottom line

If you notice any of these signs in your water heater, it’s time for a professional inspection and possible repair. If you notice any of these signs, contact your local plumber immediately so that you can avoid a dangerous situation. And if your water heater is new or less than five years old, read on for more information on when to replace it in the future.

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.
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.
  • 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.
  • 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.
