Strap your water heater
A full tank water heater can weigh several hundred pounds. In a quake it can tip over and tear its gas and water connections. California requires water heaters to be braced with two straps, one in the upper third of the tank and one in the lower third, anchored to the wall.
Tip: Look at your water heater now. If you don’t see two metal straps wrapped around it and fastened to the wall, have it strapped.
Use flexible connectors
Rigid connections can snap when a water heater or appliance shifts. Flexible gas and water connectors allow a little movement without breaking. Old flexible gas connectors, especially uncoated brass ones, should be replaced with modern coated connectors.
Consider an earthquake gas shutoff valve
An earthquake shutoff valve mounts at your gas meter and automatically stops the gas during strong shaking, which helps prevent fires from broken gas lines. Some cities require one for new construction or major remodels, and it should be installed by a licensed plumber.
If the valve trips, check for gas smells and damage before resetting it. Pilot lights will need to be relit afterward.
Know your shutoffs
- Main water shutoff: usually at the front of the house, or at the meter by the curb.
- Gas shutoff: at the gas meter. It takes a wrench to turn it a quarter turn.
- Electrical panel: know which breaker controls the water heater.
Only turn off the gas if you smell gas, hear a hiss or see damage. Once it’s off, SoCalGas needs to turn it back on and relight your appliances.
Store emergency water
Your water heater tank holds clean water you can use in an emergency. Keep a few days of bottled water too, at least one gallon per person per day.
After a quake: a plumbing checklist
- Smell for gas. If you smell it, leave and call SoCalGas or 911 from outside.
- Check under sinks, around the water heater and along visible pipes for leaks.
- If you see sewer or drain damage, don’t flush toilets until the lines are checked.
- Look at the water heater straps and connections.
- Call a licensed plumber for anything leaking, damaged or uncertain.
