Answers to frequently asked water heater replacement questions from O'Fallon homeowners.
Replace your water heater in O'Fallon when it is over 10 to 12 years old, produces rusty or discolored water indicating internal corrosion, leaks from the tank body, requires frequent repairs, or no longer meets your household hot water demand. A water heater approaching these conditions often fails unexpectedly — replacement before failure avoids an emergency.
Yes. Magnet Plumbing converts tank water heater systems to tankless in O'Fallon, IL. The conversion requires confirming adequate gas supply capacity or electrical service, installing proper venting for the new unit, and making connection changes. Our plumbers assess your existing infrastructure and advise on what is required for a successful tankless conversion at your O'Fallon home.
Most O'Fallon jurisdictions in IL require a permit for water heater replacement to ensure the installation is inspected for code compliance. Magnet Plumbing handles the permit process for O'Fallon water heater replacements as part of our installation service, so you do not need to navigate the permit office on your own.
Tank water heaters cost less upfront and are simpler to install. Tankless units provide endless hot water on demand and typically have lower operating costs, but cost more initially.
