Answers to frequently asked water heater replacement questions from Fairfax homeowners.
Replace your water heater in Fairfax 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.
Extend the life of your new water heater in Fairfax 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 Fairfax to keep your unit running efficiently.
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 Fairfax home.
Standard tank water heater replacement in Fairfax 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 Fairfax in a single visit with same-day or next-day scheduling.
Our reputation is built on results. Here is what our customers have to say.
"Our 1970s galvanized pipes were failing one joint at a time. Got three bids on a whole-house repipe and these guys were competitive on price and had the best timeline. Seven days start to finish, minimal drywall damage, and water pressure is dramatically better throughout the house. Worth every dollar."
"They are the best. They come when they say they will, fair pricing, are attentive to detail, protect the floors, are friendly and professional. Very different from plumbers we have used in the past. Thank you Saul!"
"Main water line burst and we had a river in the front yard. They isolated the break, got the water back on within a few hours, and replaced the section cleanly the next day. Excellent emergency response."
