Hot water is one of those modern conveniences we often take for granted-until it’s gone. Whether you’re jumping in the shower, washing dishes, or doing laundry, your water heater plays a vital role in your home’s comfort and functionality. But like all appliances, it has a lifespan.
Recognizing the early signs your hot water heater is failing can save you from an icy surprise and prevent major water damage or energy waste. Here are five key signs your hot water heater is failing-and what you should do about it.
1. Inconsistent or Lukewarm Water
If you’ve noticed that your hot water just isn’t as hot as it used to be-or worse, it fluctuates mid-shower-you may be dealing with a failing heating element or sediment buildup in the tank.
Why it happens:
Over time, minerals from hard water can accumulate inside your tank, insulating the heating element and reducing its efficiency. In electric heaters, this buildup can cover the heating coils entirely. In gas models, sediment can block the burner or reduce heat transfer.
What to do:
Call a professional from Pipeworks to flush the tank and inspect the elements. If the water heater is more than 8–10 years old, replacement might be the most cost-effective solution.
2. Strange Noises from the Tank
Is your water heater making rumbling, popping, or banging sounds? Don’t ignore it. These noises are usually caused by hardened sediment in the tank creating hot spots or trapping water beneath it.
Why it happens:
Sediment buildup is common in areas with hard water. As it accumulates and hardens, it causes your heater to work harder, which not only creates noise but can also lead to overheating and internal damage.
What to do:
If you catch this early, a professional flush and cleaning can extend the life of the unit. However, if the noises are accompanied by leaks or temperature issues, it’s likely time for a replacement.
3. Rusty or Discolored Water
When rusty or cloudy water starts flowing from your hot water tap, it’s a clear red flag.
Why it happens:
The inside of your water heater tank contains a sacrificial anode rod that helps prevent rust. Once that rod is fully corroded, the tank itself starts to rust. This can lead to water discoloration-and eventually tank failure.
What to do:
Try draining a few gallons from your water heater into a clear container. If it’s discolored, contact Pipeworks. We’ll determine whether the issue is in the tank or your home’s piping. If it’s the tank, replacing the anode rod might help, but if rust has taken hold, replacement is the safest option.
4. Water Around the Base of the Heater
If you find moisture, puddles, or corrosion at the base of your water heater, don’t wait-this can indicate a serious issue.
Why it happens:
A small crack or loose connection could be leaking intermittently as the metal expands and contracts with heat. Over time, those cracks get worse, and what starts as a slow leak can quickly turn into a flood.
What to do:
First, turn off the power or gas supply and call Pipeworks immediately. A leaking water heater often needs to be replaced. We’ll inspect the tank and plumbing connections to confirm the source and provide a clear, honest recommendation.
5. Your Water Heater Is Over 10 Years Old
Even if everything seems to be working fine, age matters. Most traditional tank water heaters last between 8 and 12 years. After that, you’re living on borrowed time.
Why it matters:
Old units are not only more prone to failure-they’re also less efficient, which means higher energy bills. Modern high-efficiency units heat faster, retain heat longer, and use less energy.
What to do:
Check the manufacturer’s label for the installation date (usually located on the side of the tank). If your unit is past its prime, schedule an evaluation with Pipeworks. We can help you choose between gas, electric, or tankless options based on your home and budget.
