Magnet Plumbing installs your new water heater in Chelmsford, MA to code — making all gas or electrical connections, installing the T&P relief valve and discharge tube, adding an expansion tank if required, and ensuring proper venting for the unit type.

Answers to frequently asked water heater replacement questions from Chelmsford homeowners.
Replace your water heater in Chelmsford 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 Chelmsford 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 Chelmsford jurisdictions in MA require a permit for water heater replacement to ensure the installation is inspected for code compliance. Magnet Plumbing handles the permit process for Chelmsford water heater replacements as part of our installation service, so you do not need to navigate the permit office on your own.
Extend the life of your new water heater in Chelmsford 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 Chelmsford to keep your unit running efficiently.
