Common Issues
Common Water Heater Problems
No Hot Water
A tripped breaker, a bad heating element or a failed thermostat are the usual suspects.
Not Enough Hot Water
Sediment buildup reduces the effective tank capacity over time.
Rusty or Discolored Water
This often signals the tank itself is corroding from the inside and nearing the end of its life.
Leaking Tank
Once the tank itself leaks, the unit typically needs to be replaced rather than repaired.
Strange Noises
Popping, rumbling or knocking sounds are usually caused by sediment buildup at the bottom of the tank.
Pilot Light Won't Stay Lit
A faulty thermocouple is a common and usually inexpensive fix for gas water heaters.

Prevention
Maintenance Tips to Avoid Bigger Problems
Flush the Tank Yearly
Draining and flushing sediment once a year helps the unit run efficiently and last longer.
Check the Pressure Relief Valve
Testing this valve annually helps prevent pressure buildup and protects the tank.
Set the Right Temperature
120 degrees is typically hot enough for household use and reduces strain on the tank.
Know Your Tank's Age
Most tank water heaters last 8 to 12 years. Knowing your unit's age helps you plan ahead instead of facing a surprise failure.
