Water Heater Replacement (Tank)
A water heater usually fails at the worst time, and the leak can damage a floor within hours. A replacement takes a few hours when done by a licensed plumber who handles the old unit, the new connections and the safety devices. NorTech connects you with vetted plumbers who set their own price, pull the permit and make sure the new heater meets current code.

Replace or repair, and what to choose
Tank water heaters generally last 8 to 12 years, and rust, leaks at the base or sediment-filled tanks mean replacement. A plumber can compare repair and replacement and recommend a size based on your household. Warranties, efficiency ratings and recovery rates differ between models, and a larger tank is not always better. If you are considering a tankless or heat pump unit, mention it when you book, since that is a different installation with different costs and requirements.
Code requirements that affect the install
Modern installations require seismic strapping in California, a pressure relief valve piped to a safe location, and often an expansion tank. Gas units need proper venting, combustion air and a sediment trap, while electric units need correctly sized circuits and disconnects. In garages, ignition sources may need to be raised or enclosed. A permit and inspection are part of the process, and a licensed plumber handles both and explains what the inspector will check. Clear a path to the heater and move stored items away from it before the visit, since the crew needs room to haul out the old tank safely.
What to expect on the day and after
The plumber shuts off water and gas or power, drains the old tank, removes it and sets the new heater, then makes connections and tests for leaks and proper venting. You will lose hot water for part of the day, and the new tank takes time to heat. Afterward, they will explain the temperature setting, the drain valve and the relief valve. Keep the permit sign-off and warranty registration, and flush the tank once a year to extend its life. Take a photo of the nameplate and the date code on the old unit, which helps with warranty questions and with disposal records.
