6 Signs You Need a Water Heater Replacement

signs to replace water heater

Unlike other appliances in your home, your water heater has little to no moving parts. It is a quiet unit, which can be good and bad. Although it doesn’t add to the noise in your house, it also doesn’t let you know when something is wrong – particularly as it ages. For this reason, it’s a good idea to schedule annual water heater maintenance. 


As your water heater ages, maintenance becomes more frequent and repairs more expensive. Eventually, you will need to schedule a water heater replacement in Alexandria, Virginia. If you observe ongoing problems with your current water heater, contact a plumber in your area. Below are six signs you need a water heater replacement in your home.

1. Your Water Heater Is Old

Considering it is the most used appliance in the house, your water heater is resilient, with an expected lifespan of eight to 12 years. A Common problems with an old water heater include can last up to 20 years with preventative maintenance and care. 


Once your water heater reaches its expected life, it will show signs of wear. Common problems with an old water heater include


  • Loose connections
  • Worn or broken parts
  • Cracked tank
  • Chronic water leaks
  • Inconsistent performance
  • Inefficient performance (higher water bills)


If you notice any of these problems and repairs do not work, it may be time to replace your water heater.

2. You Have a Noisy Water Heater

Manufacturers design water heaters to be super quiet. However, a unit can make noises, indicating that you need a new heater. 


Electric water heaters, mostly hear sizzling, hissing, and crackling sounds. They point to sediment build-up in the base of the tank, which can be addressed by annually flushing and draining the water heater. These sounds occur when sediment buries the lower heating element.


In most cases, addressing a noisy water heater is a simple fix. However, your water heater may not be repairable if the noise persists or you hear banging or rumbling noises. You may want to contact a plumber for water heater installation services and consider getting a new water heater.

3. There Isn’t Enough Hot Water

There are several reasons why you are not getting enough hot water. You may have a larger family and a unit that doesn’t accommodate your needs. You may have appliances that consume a lot of hot water. Your water heater may need repairs. 


Regardless, you don’t get enough hot water from your water heater. If so, it may be time for a water heater upgrade. 


  • New standard water heaters have tank reservoirs that can hold up to 120 gallons of non-water, ready to disperse when you need it. Larger heaters should provide enough hot water for a family of four with multiple appliances in the house.
  • Tankless water heaters contain a heating element that heats water as it flows through the unit. You never run out of water, regardless of how much you use. It’s ideal for a home with several occupants and appliances. Contact a local plumber in Alexandria, Virginia, for tankless water heater services to learn more about the benefits of tankless water heaters.

4. The Water Is Rusty and Tastes Funny

Rust-colored hot water occurs due to bacteria growth, pipe corrosion, tank water heater corrosion, or mineral deposits in the water supply. 


If the cause is aging plumbing, replacing those pipes or appliances could fix the issue. If there is corrosion in or outside of the tank’s surface, it almost always means the water tank or the whole water heater needs a replacement. There’s no easy way to fix this corrosion, which will spread, leading to leaking.


Remember that a little rust in water is not a health concern. However, as your water heater deteriorates, it will produce more rust, leading to health problems over time. Don’t wait to replace your water heater. 

5. Chronic Leaks Keep Reoccurring

There are plenty of opportunities for leaks from a water heater due to the pipes and connections going in and out of the unit. 


  • Valve and gasket leaks
  • Busted water tank
  • Dip tube leak
  • Inlet and outlet pipes


Water leaks can cause massive structural damage long before you realize there is a leak. These leaks can occur sporadically or simultaneously at any given time. Some leaks are fixable. Others are not. If your water heater is suffering from chronic leaks, it may be time to schedule a water heater replacement. 


Remember that not all leaks are obvious. Some hide beneath the unit. Look for signs of a leaky water heater, such as high water bills, mold, rusty pipes, discoloration on the floor or walls, and a musty smell. 

6. Your Utility Bills Have Skyrocketed

An inefficient water heater is not just a water bill concern. It’s also an electric bill concern.


Often, the first warning sign that a water heater is using too much energy comes from an electricity bill much higher than normal. For example, if your monthly electric bill is normally $100, it has shot up to $250 over the last few months, the problem may be a water heater that uses too much electricity. 


You may want to schedule a water heater inspection or energy audit to determine whether your unit is too old, damaged, or inadequate for your water consumption needs. If so, a newer, high-efficiency water heater may solve the issue and reduce your energy and water bills.
