Water Heater Safety Check: Straps, Valves, Venting, Pan

Seismic strapping

California requires water heaters to be braced or strapped against earthquake movement.

Two straps are visible around the tank, one in the upper third and one in the lower third
Straps are attached firmly to the wall framing, not just drywall
The tank does not rock when gently pushed

Relief valve and discharge pipe

A pipe runs from the temperature and pressure relief valve toward the floor or outside
The pipe end is open, not capped or threaded shut
No water is dripping from the pipe end
No rust or mineral crust around the valve

Gas units: venting and combustion

The vent pipe on top is connected and not loose or rusted through
There is no soot or scorching around the burner access
Nothing is stored against or on top of the heater
The area around the base is clear of paint, solvents and boxes

Leaks and corrosion

No water in the drain pan or on the floor
No rust stains running down the tank
Pipe connections on top are dry
The drain valve near the bottom is not dripping

What to do with the results

Anything marked 'needs attention' is worth showing a licensed plumber, ideally on a normal weekday visit. Missing straps and a blocked relief valve pipe are safety items rather than cosmetic ones. Rust or moisture at the tank body can mean the heater is nearing failure, which is easier to plan for now than at midnight.

Common questions

Do tankless heaters need straps?

Wall-mounted tankless units are installed differently. Ask a plumber what applies to yours.

The relief valve pipe drips occasionally. Is that normal?

It can mean pressure or temperature is too high, or the valve is worn. Have it checked.

How often should I do this check?

Once or twice a year is a reasonable habit, and after any earthquake.
