Answers to frequently asked water heater replacement questions from Oshkosh homeowners.
Replace your water heater in Oshkosh 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 Oshkosh 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 Oshkosh in a single visit with same-day or next-day scheduling.
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 Oshkosh home.

"Fast response, fair price, and they cleared a stubborn bathroom sink clog I had been fighting for a week. Will definitely call again."
"Had a new tankless water heater installed and could not be happier. The plumbers were punctual, clean, and walked me through the warranty and maintenance before leaving. Highly recommend for any water heater project."
"Been meaning to write this for a while. Our sewer line collapsed and we had three quotes — two wanted to dig up the whole yard, Magnet recommended trenchless. They finished in two days, no damage to the lawn, and the price came in thousands under the other guys. The Magnet team knows what they are doing and I will not hesitate to call them again."
