5 Signs That It’s Time to Replace Your Water Heater

Hot water is a necessity that most people cannot live without. Most households around the world rely on water heaters on a daily basis. From taking a hot shower after a tiresome day to washing dishes and laundry, the average person can utilize a water heater for up to 20 times per day. When you multiply that consumption by the number of people in a household, the demands placed on a water heater are immense. After some time, your water heater may fail, thus necessitating a replacement. But how do you determine the right time to replace your water heater? Here are some five signs to consider.


Every mechanical device has a certain lifespan. Even if you buy the best tankless water heater on the market, it will require a replacement when its lifespan is over. If your water heater has exceeded its lifespan, various things can occur. For example, it can crack, parts may fail, or corrosion may develop. Majority of the tanked water heaters available today have a lifespan of ten years. It’s therefore important to know its age to ensure timely replacement. If you are not sure about its age, then you just need to check its serial number. Most of the serial numbers on water heaters include the month and the year when it was made. Visit your manufacturer’s website to ascertain these numbers.

Unusual Noises

A water heater can produce various noises when it’s operational. Most water heaters are fitted in areas where the homeowner rarely visits, such as basements or in a corner. However, it’s advisable to spend a few minutes in the area regularly to determine whether the water heater is making any unusual noises. If your unit is producing unusual noises, there is a high possibility of sediment build up. As the sediments form at the bottom of the tank, they begin to grow thicker and harden. If your water heater is making noise due to sediment buildup, there are high chances that it will leak eventually. To prevent this situation, flush the tank regularly to drain the sediments. An annual flush is highly recommended. If the unit is still making noise, then there might be other issues.

Rusty water

It’s advisable to check the anode rod of your water heater regularly. If it’s damaged or worn out, then you should replace it immediately. Doing so will extend its life. The anode rod plays a significant role towards the water purification process. It attracts corrosive materials present in water, thus ensuring you end up with clean and healthy water for your needs. However, it also rust away slowly during the course of its time. Therefore, if you fail to replace it on time, the corrosive materials will eventually start damaging the entire unit. If you notice rusty water flowing through your faucet, there is a high possibility of corrosion taking place due to a dysfunctional anode rod. Replace it immediately to prevent leaks and water contamination.

Cold or Lukewarm Water

If your water heater is only discharging cold or lukewarm water, then you should consider replacing it right away. Nothing is more disappointing than jumping in the shower expecting to take a hot bath, only for cold water to hit your body. Different things can go wrong. First, the burner may be dysfunctional. Second, the pilot light may also need repair. A defective thermocouple can be another issue. Most of these issues require a professional plumber to diagnose the problem. Your plumber will advise you on whether to repair or replace the entire unit.

Leaking Water

As your water heater comes to the end of its life, you will start noticing some water collecting around the tank. If you see water, the chances are high that the tank is leaking. If your water heater is installed inside the house, leaking water can cause extensive property damage. Leaks usually occur as the tank contracts and expand. If the leaking issues are not addressed on time, the holes will continue increasing in size, leading to further damage. The entire tank can even break, thus leading to major flooding.

Water is one of the most important resources in a household. Hot water is needed in various situations during the day. Therefore, it’s important to ensure your water heater is in great condition. If you notice any of the above signs, then it’s time to replace your water heater. Always ensure a professional plumber handles the entire project.
