Water Heater Replacement FAQ — Chesterfield, MO

What Chesterfield homeowners want to know about water heater replacement — answered by our licensed plumbers.

How do I know when to replace my water heater in Chesterfield?

Replace your water heater in Chesterfield 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.

Do I need a permit to replace my water heater in Chesterfield, MO?

Most Chesterfield 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 Chesterfield water heater replacements as part of our installation service, so you do not need to navigate the permit office on your own.

What size water heater do I need for my Chesterfield home?

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 Chesterfield home.

How can I extend the life of my new water heater in Chesterfield?

Extend the life of your new water heater in Chesterfield 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 Chesterfield to keep your unit running efficiently.

★★★★★

"We noticed our water bill doubling month over month and could not find anything visible. These guys came out with the leak detection equipment and located a slab leak under the living room in about thirty minutes. The repair was minimally invasive — small access cut, patched afterward, and the bill is back to normal. Really impressed with the professionalism."
