How do you know if you need a replacement? If your tank water heater is more than 10 years old, it may be time to consider replacing it.  A common sign of trouble with any water heater is often a higher utility bill. If your unit is using extra energy to provide the same amount of hot water, it’s time to take a closer look at it. 

What to look for:

• Leaks: If your water heater is leaking, it must be replaced immediately. Leaks are usually the result of pressure buildup inside the tank. This happens when the water pressure or temperature is too high, or when the unit’s relief valve is not working properly. Neglecting a leak can lead to a tank explosion. Signs of leaks include moisture or puddles around the water heater’s base and water corrosion on the side of your tank. Contact a trusted professional immediately if you notice these warning signs.
• Knocking Noises: Loud noises are an indication of sediment buildup. As sediment hardens, it can move around the tank and cause knocking, rumbling and gurgling sounds. To preserve your water heater and prevent unnecessary wear and tear, have it flushed regularly to remove any deposits from the tank’s heating elements.
• Rusty Water: Water discoloration is a clear sign your unit is underperforming. Rust-colored water or water with a metallic odor can mean a few things. Either the sacrificial anode rod needs to be replaced or the tank itself is beginning to rust, often due to corrosion at the steel lining. A corroded tank must be replaced as soon as possible.
• Cloudy Water: When you see cloudy water, it may indicate you have a sediment buildup in your water heater.
• Cold Water: If your water remains cold even after you turn on the hot water tap, a heating element may be broken.
