Water heater replacement cost by type.
Installed prices for Castaic, adjusted for local labor. Larger tanks and code upgrades move the number up.
In Castaic, where the median home was built in 1992, many water heaters are approaching or past their expected lifespan. Replacing a unit involves local costs ranging from $750–$1,850 for a gas tank to $1,700–$3,700 for a heat pump model.

Permits are also necessary under the California Plumbing Code. For most homeowners, a heat pump water heater is a strong fit due to federal tax credits (30% up to $2,000) and long-term energy savings, though upfront costs are higher.

Sediment buildup
Hard water minerals accumulate in the tank, reducing efficiency and causing rumbling noises. Flushing annually helps, but older units may need replacement.
Seismic strapping failure
Castaic is in an earthquake-prone region. Improper or missing straps can cause the water heater to tip during a quake, leading to gas leaks or flooding.
Expansion tank problems
Closed plumbing systems require an expansion tank to prevent pressure buildup. A failed expansion tank can cause the T&P valve to leak or the water heater to fail prematurely.
