Hot showers are easy to take for granted, until your water heater suddenly stops working. In Wichita, Kansas, hard water, seasonal temperature swings, and normal wear can all shorten the lifespan of your system.

At Benjamin Franklin Plumbing of Wichita, we often get emergency calls that could have been prevented if the warning signs had been caught earlier. Here’s how to tell if your water heater is about to fail, before you’re stuck with cold water.

How Long Do Water Heaters Last?

Most traditional tank water heaters last 8-12 years. Tankless systems can last longer, but still show signs of wear over time. If your unit is approaching (or past) this age range, it’s smart to watch for trouble and consider a water heater replacement.

Not sure how old yours is? Check the serial number on the tank, or have a local plumber take a look.

8 Warning Signs Your Water Heater May Be Failing

1. Your Hot Water Runs Out Faster Than It Used To

If your showers are getting shorter and you’re running out of hot water quickly, sediment buildup may be taking up space inside the tank or the heating element may be wearing out.

2. Rumbling, Popping, or Banging Noises

Strange sounds from the tank are often caused by hardened sediment heating and shifting around. This forces your water heater to work harder and can lead to overheating or tank damage.

3. Inconsistent Water Temperature

Water going from hot to lukewarm (or suddenly cold) could mean a failing heating element, thermostat issues, or heavy sediment buildup.

4. Rusty or Discolored Water

If only your hot water looks rusty, your water heater tank may be corroding from the inside. This is often a sign the system is nearing the end of its life.

5. Leaks Around the Base of the Tank

Even small amounts of water pooling around your unit can signal internal tank fractures. Once the tank itself starts leaking, replacement is usually the only option.

6. Rising Energy Bills

An aging water heater loses efficiency. If your utility bills are climbing without a clear reason, your system may be working harder than it should.

7. Your Unit Is Over 10 Years Old

Age alone doesn’t mean immediate failure, but the risk increases significantly after the 10-year mark, especially in Wichita homes with mineral-heavy water.

8. Frequent Repairs

If you’re calling for repairs more than once a year, replacing the unit may cost less in the long run than continuing to fix an aging system.

Why Wichita Water Conditions Matter

Wichita-area water can contain minerals that lead to sediment buildup inside water heaters. Over time, this buildup reduces efficiency, stresses components, and shortens the life of the tank.

Routine flushing can help, but once corrosion or tank damage begins, replacement is often the safest option.

Should You Repair or Replace Your Water Heater?

Here’s a simple rule of thumb:

  • Minor issue + newer unit → Water heater Repair may make sense

  • Major issue + older unit → Water heater Replacement is usually more cost-effective

A professional inspection can help you avoid putting money into a system that’s already on its last leg.

Don’t Wait for a Cold Shower Emergency

Water heaters rarely fail at a convenient time. Catching the warning signs early can help you plan ahead instead of dealing with a burst tank or no hot water.

If you’ve noticed any of these symptoms, Benjamin Franklin Plumbing of Wichita can inspect your system and help you decide whether repair or replacement is the best move.
