How to Know When It’s Time to Replace Your Water Heater
Helpful Tips for Homeowners in DuPage County, IL
At Herman Services Home Repairs, I believe in the value of preventative maintenance—but like many homeowners, I don’t always get around to it. For example, I have a 40-gallon gas water heater with a 12-year warranty. It’s now 15 years old and still running, but I know it’s living on borrowed time.
Recently, a customer asked me how long water heaters actually last. She mentioned that in her condo building, some of the electric water heaters were over 30 years old! That may be rare, but it reminded me how important it is to understand the warning signs of a failing unit—so you’re not caught off guard.
Here’s what every homeowner in DuPage County should know about hot water heaters:
1. How Old Is Your Water Heater?
Most standard 40-gallon gas water heaters last 8 to 12 years, especially in areas with hard water like DuPage County. If your unit is over 10 years old, it’s time to start watching for signs of failure. You can usually find the manufacture date on a label or encoded in the serial number.
2. Rusty or Discolored Water
If you’re noticing brown or rusty water when running hot taps, the inside of your tank may be corroding. This is a common warning sign that your water heater is nearing the end of its lifespan.
3. Water Around the Base
Finding moisture or puddles near the bottom of your water heater can indicate a slow leak. Even minor leaks can grow quickly and lead to significant water damage if ignored.
4. Strange Noises
Popping, rumbling, or banging sounds often come from sediment buildup inside the tank. This not only reduces heating efficiency but can also damage the tank over time.
5. Inconsistent or Cold Water
Running out of hot water too quickly or dealing with fluctuating water temperatures is another red flag. This could mean your heater is struggling to function due to age or internal damage
6. Higher Utility Bills
Older water heaters lose efficiency, which can lead to higher gas or electric bills even if your usage hasn’t changed. If your energy costs are creeping up, your water heater might be the culprit.
DuPage County Homeowner Tip
Our local water tends to be moderate to hard, which means mineral deposits form faster. To extend the life of your water heater:
Flush the tank annually
Check or replace the anode rod every few years
These small steps can make a big difference in your water heater’s performance and longevity.
Don’t Wait for a Cold Shower
Your water heater may not be top of mind—until it fails. Knowing the signs of wear can help you plan ahead, avoid costly water damage, and keep your home running smoothly.
