Magnet Plumbing removes your old water heater in Rochester, NH 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 Rochester 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.
Answers to frequently asked water heater replacement questions from Rochester homeowners.
Replace your water heater in Rochester 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.
Standard tank water heater replacement in Rochester 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 Rochester in a single visit with same-day or next-day scheduling.
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 Rochester 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.
Extend the life of your new water heater in Rochester by flushing the tank annually to remove sediment, replacing the anode rod every 3 to 5 years, setting the thermostat to 120°F to reduce mineral buildup and tank stress, and inspecting the T&P valve annually. Magnet Plumbing offers annual water heater maintenance service in Rochester to keep your unit running efficiently.
