Water heater replacement in San Diego
A tank water heater typically lasts 10 to 15 years, according to the U.S. Department of Energy. In San Diego, hard water adds sediment to the bottom of the tank, and once a tank starts leaking from the bottom it cannot be repaired, only replaced.

Replacement is not just a swap. In the City of San Diego it needs a plumbing permit, and the new heater has to meet current California rules: earthquake straps, a drain pan where a leak could cause damage, and thermal expansion control on closed water systems.
Signs it is time to replace
- The heater is 10 years old or more (check the date on the label)
- Water is leaking from the tank itself, not a fitting
- Rusty or discolored hot water
- Rumbling or popping from sediment in the tank
- Hot water runs out much faster than it used to
How a replacement is done
Choose the type and size
Like-for-like tank replacement is simplest. Switching to tankless or a heat pump water heater changes the gas, venting or electrical work and the permit type.
Pull the permit
In the City of San Diego, a standard tank replacement qualifies for a simple "no-plan" plumbing permit. Tankless units need a plan-required permit. Other cities issue their own permits.
Install to current code
The new heater is strapped for earthquakes, gets a drain pan where a leak could damage the home, and an expansion tank if the water system is closed by a regulator or check valve.
Inspection and haul-away
The permit is closed with an inspection, and the old tank is removed and disposed of.
Questions about water heater replacement
How long do water heaters last?
The U.S. Department of Energy puts tank water heaters at 10 to 15 years and tankless units at up to about 20. Hard water and skipped maintenance shorten that.
Do I need a permit to replace a water heater in San Diego?
Yes. In the City of San Diego, a standard tank replacement uses a simple "no-plan" plumbing permit; tankless installations and historic properties need a plan-required permit. Other cities in the county have their own permit offices.
Should I replace it before it fails?
If the heater is past 10 years and showing signs like rust or rumbling, planning the replacement is usually cheaper than an emergency swap plus water damage cleanup.
