When your hot water runs out mid-shower, you're not just inconvenienced — you're facing one of the most common plumbing issues for North Metro Atlanta homeowners: water heater repair. Whether you live in Cartersville, Woodstock, Kennesaw, or Acworth, GA, knowing the main parts of a water heater that can fail (and the warning signs to watch for) can help you avoid emergencies and plan for a timely water heater replacement before disaster strikes.
🛠️ Key Water Heater Parts That Often Need Repair
Heating Elements or Gas Burner Assembly
Electric water heaters rely on upper and lower heating elements to warm water. Over time, these elements burn out or become coated with mineral deposits. Gas water heaters have a burner assembly that can clog or corrode.

Thermostat & Gas Control Valve
Faulty thermostats (electric) or gas control valves (gas) are frequent culprits when your water heater stops heating properly.
-
Water heater repair sign: Water that's too hot, too cold, or fluctuates unpredictably.
Anode Rod
This "sacrificial" rod protects the tank from corrosion. Once it's consumed, your tank starts to rust.
-

Temperature & Pressure Relief (T&P) Valve
This safety device prevents dangerous pressure build-up. Mineral buildup or corrosion can cause it to stick or leak.
-
Water heater repair sign: Persistent dripping, water pooling under the tank, or hissing sounds.
Tank Liner & Weld Seams
As your water heater ages, the steel tank and its lining can corrode or crack.
-
Water heater repair sign: Rust streaks, water leaking around the base, or damp flooring near the unit.
Drain Valve
Used to flush out sediment. Over time it can clog, leak, or seize shut.

🔎 How to Tell If You Need Water Heater Repair or Replacement
Most standard tank water heaters last 8-12 years in the humid Georgia climate. If you notice any of these warning signs, it's time to call a licensed plumber for water heater repair near you:
-
Inconsistent hot water or longer reheating times
-
Rust or corrosion around valves or seams
-
Rumbling or popping noises from sediment buildup
-
Leaks or moisture around the base of the tank
-
Higher energy bills because your unit is working harder
When your system is in the 8-10-year range and showing one or more of these issues, a professional water heater inspection can help determine if repair is worthwhile or if a full hot water heater replacement will save you money long term.
