Common Water Heater Issues in Summerville
Sediment Buildup
Hard water minerals accumulate in tank-style heaters, reducing efficiency and causing rumbling noises. Annual flushing helps.
Leaking Tanks
Corrosion from age (especially in homes built around 1999) leads to leaks. Replacement is often the only solution.
Inadequate Capacity
Older 40-gallon tanks may not meet household demand. Upgrading to a larger tank or tankless unit can help.
What to Expect During a Water Heater Replacement
A licensed plumber will pull a permit and inspect the existing setup. They'll disconnect and remove the old unit, install the new one per IPC code, and add an expansion tank if needed. The job typically takes 4–6 hours. After installation, they'll test for leaks and proper temperature. Expect upfront pricing before work begins.
