Don’t Wait for a Flood: 7 Critical Signs Your 10+ Year Old Water Heater Is About to Fail
Your water heater is one of the hardest-working appliances in your home, quietly heating water 24/7 to keep your family comfortable. But like any mechanical system, it won’t last forever. The average lifespan of a water heater is between 9 to 10 years, and ENERGY STAR® recommends replacing your storage water heater if it’s more than 10 years old. If your water heater has crossed the decade mark, it’s time to watch for warning signs that could save you from an expensive emergency replacement and potential water damage.
Why Age Matters More Than You Think
Water heaters over 10 years old should probably be replaced, with most units lasting around 10 to 12 years, and if you’re lucky, maybe 15. The older the unit is, the greater the chance it has of starting to leak or suddenly failing, and this can lead to inconvenient breakdowns, especially during peak usage times, and can result in costly emergency repairs or replacements.
Ignoring these issues can lead to sudden failure of the water heater, cold water, and in some cases, tank rupture and water damage to the floor and carpets. The other downside to sudden failure is that you may have to schedule an emergency replacement with the plumber, which can be more expensive, and typically limit your replacement options to inefficient models with high operating costs.
7 Warning Signs Your Water Heater Needs Immediate Attention
1. Visible Rust and Corrosion
Corrosion is a sign that the water heater is breaking down. If you notice orange-hued water coming from one or more fixtures in your home, this is a sign of excess rust in the tank. Water discoloration is a clear sign your unit is underperforming. Rust-colored water or water with a metallic odor can mean 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.
2. Leaks Around the Base
If your water heater is above 10 years of age, you may begin to notice leaks at the bottom of your tank. To avoid damage to your flooring, furniture, and equipment, we recommend replacing the water heater. If your water heater is leaking, it must be replaced immediately. Leaks are usually the result of pressure buildup inside the tank, and neglecting a leak can lead to a tank explosion.
3. Inconsistent Water Temperature
If the water from your kitchen or bathroom sinks is cold or room temperature, this may be a sign its time to replace your water heater. This issue may be caused by a broken or malfunctioning heating element. One of the first signs of a failing water heater is inconsistent water temperature.
4. Strange 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. These sounds indicate your water heater is working harder than it should, reducing efficiency and shortening its lifespan.
5. Metallic Taste or Odors
A metallic taste in your water may be caused by corrosion on the inside of the water tank. These metals aren’t safe to consume, so it’s best to replace your water heater entirely to prevent further ingestion by your loved ones. The prominence of strange odors in your water may be an indicator of a deteriorating tank. When the interior of a water tank begins to break down, the likelihood of finding dangerous chemicals and materials in your water increases.
6. Rising Energy Bills
If you notice a spike in your utility bills without a significant change in your hot water usage, it could be caused by your water heater. As water heaters age, they may struggle to maintain the desired water temperature, causing them to run frequently and consume more energy. Older water heaters are significantly less energy-efficient than modern models. As they age, they consume more energy to heat the same amount of water, leading to higher utility bills.
7. Frequent Repairs
Frequent breakdowns and repairs can be costly and inconvenient, and they often occur more as the water heater gets older. When the cost of repairs begins to outweigh the benefits of keeping the existing water heater, it may be time to consider replacing it. If you find yourself repeatedly calling for repairs while observing a continued decline in your water heater’s performance, you might just be prolonging the inevitable. This is especially likely to be true if your water heater is also fairly old already. When you reach this point, starting fresh with a new water heater will usually be more cost effective than continuing to pour money into one that’s dying.
The Cost of Waiting Too Long
A failing water heater can cause substantial water damage if it leaks or bursts. Water damage can lead to expensive repairs, mold growth, and damage to personal property. Proactively replacing an aging unit can prevent these risks. The concern once the steel has started to rust through is that the rust can weaken the tank to the point where the pressure of the hot water causes it to suddenly burst and create a major flood. If this happens and you’re not there to immediately shut the water off, it can result in thousands of gallons of water flooding the entire area and causing extensive water damage.
