The DSA details do not apply to every situation, but they are a minimal guide to start with. There are other manufactured systems available. Their installation instructions should be complied with. We also suggest that you consult with a licensed Structural Engineer for any atypical situations or if you questions/concerns regarding your current water heater seismic restraint. Remember, a loose water heater is a dangerous water heater!
