A water heater rarely quits out of nowhere. Most of the time, it gives off warning signs—small at first, then increasingly hard to ignore. Catching those signs early can save you from cold showers, higher energy bills, and even water damage.
Here are the five most common signs your water heater is failing and when it’s time to call in a professional.
1. Your Water Isn’t Getting as Hot as It Used To
If your showers don’t stay warm or you’re running out of hot water quicker than normal, it’s often a sign of:
-
A failing heating element
-
Sediment buildup in the tank
-
A water heater that’s nearing the end of its lifespan
This usually starts gradually. If you’ve already tried adjusting the thermostat and nothing’s improved, it’s time to have it inspected.
2. Strange Noises Coming From the Tank
Hissing… popping… rumbling… none of these should be coming from your water heater.
These noises typically mean there is sediment buildup at the bottom of the tank. When the burner heats water trapped beneath the sediment, it creates popping or rumbling sounds. Over time, this causes:
-
Reduced efficiency
-
Overheating
-
Damage to the tank
Ignoring this can shorten your water heater’s lifespan dramatically.
3. Rusty or Discolored Water
If your hot water looks rusty, cloudy, or discolored, it may mean:
-
Corrosion inside the tank
-
A failing anode rod
-
Rust forming on the inside of your unit
Once rust begins inside the tank, the only real solution is replacement—because rusted tanks eventually leak.
Tip: If only the hot water is discolored (not the cold), the issue is almost always the water heater.
4. Leaks Around the Base of the Water Heater
Even a small puddle around the bottom of your water heater is a red flag. Causes include:
-
Loose connections
-
Faulty pressure relief valve
-
Cracks from years of heating and cooling cycles
A leaking tank cannot be repaired. If the tank itself is compromised, replacement is necessary to prevent water damage.
5. Your Water Heater Is 10+ Years Old
Most tank-style water heaters last 8-12 years. Once yours passes the 10-year mark, you’re more likely to experience:
-
Inefficiency
-
Frequent repairs
-
Sudden failure
Tankless water heaters can last longer, but they also show signs of wear over time.
If you’re not sure how old your water heater is, the serial number on the label will tell you.
