How to Spot the Signs of a Failing Water Heater

Spot the Signs Before Water Heater Replacement Is Imminent

Losing the water heater can be a major problem for a home or business. Without hot water, restaurants can’t wash dishes, and the family can’t bathe comfortably at the end of the day. Unfortunately, most owners will miss the signs that the water heater is failing, and they will end up in an emergency when the water heater fails. 

When owners know the signs that the water heater is failing, they can take action before the unit stops providing hot water completely. Here are the three biggest signs that the water heater is nearing the end of its useful lifespan. 

Corrosion

It may seem obvious, but water and metal don’t play well together. Water tends to accelerate the corrosion of copper and steel, both of which are important components of water heaters. Water heaters have a special lining and a device called an anode rod to combat corrosion. Between these two features, corrosion can be prevented for years. However, at some point, these protective measures will fail and leave the tank vulnerable to corrosion. 

When corrosion attacks the tank, an owner can spot a few signs. First, if corrosion occurs in the tank, the water will take on a visible rusty color. If the corrosion is in the piping or nearby fittings, it may look green. It may also have a metallic taste from the iron or copper oxide. Secondly, water in contact with corrosion may have a distinct odor. 

The Water Runs Cold

If a water heater has completely failed to provide hot water, then the problem is already an emergency. However, water heaters usually fail more slowly, allowing owners time to notice the loss of hot water volume and respond appropriately. This will be especially evident in homes where everyone fights over the shower at the end of the day so they don’t run out of hot water. 

As water heaters age, they lose efficiency and the ability to recover quickly. This means the overall capacity to provide hot water will be diminished. If the tank can’t keep up, a new water heater installation can restore lost performance. 

Old, Costly Water Heater 

Maybe the best indicator of the likelihood that a water heater is about to fail is its age. Water tanks typically last around a decade, while some tankless water heaters can last for two. Finding the model and serial number of the water heater and contacting the manufacturer is a great way to figure out the unit’s age. Also, it is a good habit to write the installation date of the water heater on the unit to avoid future confusion. 

If the water heater’s age is unknown, the next best thing is to pay attention to repair bills. Water heater repairs shouldn’t be necessary too often until the unit starts to age. At some point, as repair bills start adding up, it will be a better investment to replace the water heater instead of scheduling repairs.
