Magnet Plumbing removes your old water heater in O'Fallon, MO carefully — draining the tank, disconnecting all utilities safely, and hauling the unit away. We inspect the installation area for any issues that should be addressed before the new unit is installed.
Our licensed O'Fallon plumber installs the new water heater with all code-required components — proper supply line connections, gas or electrical hookup, T&P valve and drain tube, expansion tank if required by local code, and correct venting.
We fill the tank, start the unit, check for leaks at all connections, and verify the water reaches the correct temperature. We walk you through the controls and any maintenance the manufacturer recommends.
What O'Fallon homeowners want to know about water heater replacement — answered by our licensed plumbers.
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.
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. For most O'Fallon families, a quality tank unit in the correct size is the most cost-effective choice. Our plumbers help you compare the total cost of ownership for your specific situation.
Most O'Fallon jurisdictions in MO 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.
Standard tank water heater replacement in O'Fallon typically takes 2 to 3 hours including disconnection, removal, installation, and testing. Tankless water heater installation may take 3 to 5 hours depending on the venting and gas or electrical work required. Magnet Plumbing completes most water heater replacements in O'Fallon in a single visit with same-day or next-day scheduling.

"Bought a new house and had a pre-purchase sewer camera inspection done. The plumber walked me through the footage and pointed out one section that would need attention in a few years. Honest assessment, no upsell pressure."
"Our main line backed up on a Saturday night and the Magnet Plumbing crew showed up within the hour. They cleared it, camera inspected it, and gave us a quote to fix the damaged section. Professional from start to finish."
"Magnet Plumbing fixed a leaky kitchen faucet and installed a new toilet in the master bath on the same visit. They were in and out in a few hours and cleaned up everything before they left. Will absolutely use them again."
