A typical gas water heater has a lifespan of 10 to 12 years with proper maintenance. Factors like water quality in San Leandro, such as hard water causing mineral buildup, and usage patterns can influence its longevity.
Absolutely. Modern gas water heaters are much more energy-efficient than older models, especially if your current unit is over 10 years old. Upgrading can lead to real savings on your monthly utility bills by reducing gas use.
Tankless can make sense if you want endless hot water and plan to stay long term, but upfront costs are higher. We can price both options so you can weigh them side by side.
It is risky. Gas leaks, poor venting and incorrect relief valve installation can create fire and carbon monoxide hazards. A licensed plumber also takes care of permits and inspection.
Replacing a gas water heater involves working with gas lines, water connections and venting, which can be dangerous if not done correctly. It is strongly recommended to hire a licensed professional like FBL Plumbing for safety and code compliance.
