Water Heaters
What Is Seismic Strapping (Oregon Code)?
Definition
Seismic strapping is a code-required bracing system — typically two metal straps anchored into wall studs — that keeps a tank water heater from tipping over during an earthquake, which could shear off the gas line or water connections and create a fire or flood hazard.
Why it matters for your home
Oregon building code requires seismic strapping on water heater installations, so it isn't optional trim on a quote — it should already be included on any legitimate installation or replacement in this state.
What to do about it
If a water heater quote doesn't mention strapping, ask directly whether it's included — it should be, on every install here.
