Earthquake strapping, also called seismic strapping, secures water heaters and large appliances to a building’s structure to prevent tipping during earthquakes. Heavy-duty metal straps wrap around the unit and anchor into wall studs or framing. In seismic regions, building codes often require strapping to reduce risks of water damage, gas leaks, and electrical hazards.

Two straps and secure anchors reduce tip-over risk.
A homeowner in a seismic zone installs earthquake straps on a new water heater, anchoring to wall studs to meet local code and reduce damage risk during tremors.
Install one strap near the top and one near the bottom, tightened securely without denting the tank. Inspect straps periodically for loosening or corrosion.
“Install one strap near the top and one near the bottom, tightened securely without denting the tank. Inspect straps periodically for loosening or corrosion.”
Strapping requirements have significantly reduced fire and water damage after major earthquakes.
Is earthquake strapping required by code?
Many seismic regions require it for water heaters. Check local building codes for specific rules.
Where should the straps be placed?
Typically one strap in the upper third and one in the lower third of the tank, anchored into wall studs.
Can I install earthquake strapping myself?
Some homeowners do, but professional installation helps ensure proper anchoring and code compliance.
