Magnet Plumbing installs your new water heater in Cottage Grove, WI 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 Cottage Grove homeowners.
Replace your water heater in Cottage Grove 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 Cottage Grove 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.
For a tank water heater, the right size depends on the number of occupants: 30 to 40 gallons for 1 to 2 people, 40 to 50 gallons for 3 to 4 people, and 50 to 80 gallons for larger households. For tankless units, the required flow rate in GPM determines the correct unit size. Magnet Plumbing assesses your household demand and recommends the right unit for your Cottage Grove home.
Most Cottage Grove jurisdictions in WI require a permit for water heater replacement to ensure the installation is inspected for code compliance. Magnet Plumbing handles the permit process for Cottage Grove water heater replacements as part of our installation service, so you do not need to navigate the permit office on your own.
