Safety items
- Two seismic straps wrapped around the tank and anchored to the wall, as California requires for water heaters.
- A temperature and pressure relief valve near the top of the tank.
- A discharge pipe from that valve running down to a safe location, not capped or plugged.
- On gas models, a vent pipe connected at the top and not loose or rusted through.
- Nothing stored against or on top of the heater, especially paint or solvents.
Condition items
- No water on the floor or in the drain pan.
- No rust streaks or white crust around fittings.
- No rumbling or popping when it heats, a common hard-water sediment sign.
- Hot water lasts about as long as it used to.
- The label shows the age; note it for your records.

Parts on the checklist
- Seismic strap
- A metal strap that holds the tank to the wall so it is less likely to tip in an earthquake.
- T&P relief valve
- A valve that opens if pressure or temperature in the tank gets too high.
- Drain pan
- A shallow pan under some heaters that catches small leaks.
- Sediment
- Minerals from hard water that settle at the bottom of the tank.
Common questions
How often should I do this check?
Once or twice a year is a reasonable habit, and after any earthquake.
Does replacing a water heater need a permit?
Usually yes. Check with the City of Fullerton or have the contractor handle it.
Can I add straps myself?
Strapping must be done correctly to be effective. Many homeowners have a plumber install or check it.
