Symptoms of a Faulty Water Heater

Faulty Water Heater Warning Signs 

When a water heater starts to go bad, it can be frustrating. Sometimes these issues happen randomly, but most of the time, they occur because the unit has become too old. A water heater that is ten years old or more will often start having issues, resulting in the need for a replacement. 

In addition, if a water heater begins needing frequent repairs, runs out of hot water too fast, or has inconsistent temperatures, it may point to a water heater that is going bad and needs to be replaced.  

Homeowners who notice any symptoms of a hot water heater going bad should immediately contact a professional for a consultation. Sometimes these issues may be able to be repaired, but often they will require a replacement, so it’s important to talk to a professional to determine the best course of action. 

What’s That Noise? 

soundsHot water tanks sometimes make noises – especially electric hot water tanks where an occasional crackling or hissing sound is normal. However, some sounds should be cause for concern. These sounds are usually loud and consistent and will sound like a rumbling noise inside the hot water tank. 

This rumbling sound happens when minerals such as calcium and magnesium become sediment particles that cling to the tank’s bottom. The rumbling noise will follow when this occurs, signaling a need for water heater maintenance. 

For the most part, getting rid of sediment buildup is easy and requires flushing the tank and checking or replacing the anode rod. Even if there is no sediment present, it’s important to flush the system twice a year to help prevent it from occurring in the first place. If maintenance is neglected, the sediment will cause the tank to corrode and need a replacement. 

Water is Discolored and Smelly

waterIf the water produced from the faucets connecting to a hot water tank happens to be discolored, looks rusty or musty, is unclear, or smells bad, then signs point to a hot water tank that is on its last leg. Unfortunately, these issues can occur when the unit or the pipes are corroded, leading to less-than-appealing colors and smells. 

Corrosive materials are drawn in by an anode rod to protect the water heater. However, if the anode rod is too old or worn down, the corrosion cannot be avoided as it would with a working anode rod. If the anode rod is faulty, then the tank should be drained and the rod replaced. However, in severe cases, the tank may have suffered wear and tear that is too great to be repaired, and an entire water heater replacement may be necessary.  

Faulty Heaters and Leaks 

Suppose a hot water tank is suddenly leaking. In that case, the tank should receive immediate attention from a professional plumber who can determine the problem's source and advise on the best way to proceed. Leaks that are left without attention for too long can lead to worsening damage to the water heater. 

Professionals can locate and repair leaks quickly and efficiently. However, the hot water heater will need to be replaced if the tank has suffered a crack or too much corrosion. By calling a professional as soon as possible, homeowners may be able to avoid more expensive repairs or a replacement.
