Common water heater issues in Normal homes
Sediment buildup
Hard water and sediment accumulate in the tank, reducing efficiency and causing rumbling noises. Regular flushing can extend the heater's life.
Leaking tank
Corrosion from age (typical 10-15 years) leads to leaks. In Normal's humid climate, this can happen faster if the unit is in a damp basement.
Pilot light or burner problems
Gas units may have issues with the thermocouple or gas valve, causing the pilot to go out or the burner to fail, especially in older models.
What to expect during a water heater replacement in Normal
A licensed plumber will first obtain the required permit from the local building department. They will disconnect the old unit, drain it, and remove it. The new water heater is installed according to the Illinois Plumbing Code, including an expansion tank if needed. The plumber will test for gas leaks (if gas) and proper operation. The job typically takes 2-4 hours, and the old unit is hauled away.
