How long do water heaters typically last in St. Louis?
Most tank water heaters last 8-12 years, but two local factors shift that window in St. Louis: the climate (humid continental climate with hot, humid summers, cold winters, and frequent severe weather) and the local housing stock (dense historic brick neighborhoods with aging plumbing alongside extensive suburban development across two states). Storm season power interruptions can affect water heater performance across St. Louis.
What's the most common water heater problem in St. Louis?

Should I repair or replace my water heater in St. Louis?
It depends on the unit's age, the cost of the specific repair, and whether it's failed before. As a general guideline, a repair costing more than roughly half the price of a new unit — or a tank already past 8-10 years old — usually favors replacement. A local specialist in St. Louis can give you a straight answer after a quick inspection rather than guessing from age alone.
