Top 5 Signs Your Water Heater Needs Repair Jul 12, 2025

When it comes to home maintenance, your water heater often doesn't get much attention until something goes wrong. However, recognizing the signs of a malfunctioning water heater early can save you from costly repairs or even replacement. As one of the leading plumbing service providers in Minnesota, Suburban Plumbing MN is dedicated to helping homeowners identify when their water heaters need attention. Here are the top five signs your water heater needs repair.

Firstly, if you're experiencing inconsistent hot water supply, it's a clear indicator that something is amiss. If your once-dependable water heater begins to produce water that fluctuates between hot and cold, it might be a signal of mineral deposits building up around your water heater's heating elements. These deposits limit the heater's performance, making routine water heater maintenance essential.

Next, pay attention to any unusual noises coming from your water heater. A humming or hissing sound is typically a sign of sediment buildup. As this sediment heats up and expands, it can cause rumbling or popping noises, indicating that your water heater isn't operating efficiently. This might not only increase energy expenses but could lead to overheating, posing a safety risk. Regular flushing can mitigate this issue.

Moreover, visible leaks or pooling water around your unit are unmistakable signs of trouble. Even a small leak can escalate, causing significant water damage to your home. Leaks often occur due to internal issues such as faulty valves or a corroded water tank. Ignoring these problems can lead to more severe damage, emphasizing the importance of timely water heater repairs.

Another indicator that your water heater may need attention is the water's unusual color or odor. If you notice rusty water coming from your hot water faucets, it could suggest that your tank's interior is corroded. Corrosion often leads to rust, which can contaminate your water supply. Likewise, a metallic-smelling water suggests the presence of bacteria, which might require a thorough cleaning or even replacement of the anode rod.

Lastly, consider the age of your water heater. Most units last about 8 to 12 years. If your system is within this age range and you're noticing problems, it might be more economical to replace rather than repair it. An old and outdated system not only struggles with efficiency but can also be a significant drain on energy costs, leading to higher utility bills over time.
