Water heater replacement in Lakewood, CA means removing the old tank and installing a new gas, electric or heat-pump unit with current code items: seismic straps, a relief valve discharge line, proper venting and gas connections, and often an expansion tank. In Lakewood, a water heater replacement is plumbing work that usually needs a permit, and heaters outside or in a garage may also involve planning review.
Choosing the right replacement
Most Lakewood households replace like with like: a 40- or 50-gallon gas tank in the garage or a closet. Consider household size, peak use (several showers back to back), fuel and space. Heat-pump water heaters need more room and air around them, and may need an electrical circuit.

Expect new seismic straps (required by California Health and Safety Code 19211), a properly routed relief valve discharge line, correct vent connector and clearances for gas units, a sediment trap and a new gas flex connector, and often a thermal expansion tank when the home has a pressure regulator. Garage gas heaters typically have to be raised so the ignition source sits at least 18 inches above the floor, unless the unit is listed as flammable-vapor-ignition resistant.
How long replacement takes
A like-for-like tank swap is often done in a few hours once the provider is on site. Relocating the heater, changing fuel type, upsizing the vent or adding an electrical circuit adds time. Inspection is scheduled separately with the city. Our water heater replacement cost guide lists published national ranges with dates and limitations.
