Water Heater Repair? Or Is It Time To Replace?

Sometimes a small issue can be solved with a repair such as a malfunctioning pilot light, thermostat, or minor valve issues. But, if your header is aging (over 8-12 years), tank leaks, or having recurring issues, a full replacement is usually the more cost-effective path.

FAQs About Water Heaters

How long should a water heater last?

Standard tank water heaters typically last 8–12 years. Tankless systems can last longer with proper maintenance.

Do I need a permit to replace my water heater in St. Louis?

Yes, permits are required for water heater installations. We handle that for you to ensure everything meets code.

How can I tell if I need a new unit or just a repair?

Leaks from the tank body, rust-colored water, and rising utility bills are often signs it’s time for a replacement. If it’s a small issue like a pilot light or thermostat, a repair may do the trick.

Is a tankless water heater worth the upgrade?

If your household uses a lot of hot water or you want to save space and energy, a tankless unit is a great long-term investment.

Can I get hot water faster?

Yes! Ask us about installing a hot water recirculation system to reduce waste and wait time.
