If I have an existing electric/gas water heater in or accessible from the garage, and need to replace it, must I get a permit and must I raise it 18 inches above the floor?
Yes, codes have been changed to prevent accidents. The water heater thermostat energizes the heating element when the water temperatures within the tank falls below a certain selected level. At the instant the thermostat activates, a spark results. This spark is a source of ignition for flammable or combustible vapors (i.e., gasoline) that may have accumulated along the floor of the garage. The 18-inch elevation is intended to keep ignition sources above these vapors that are heavier than air and settle to the garage floor. The permit is to ensure the water heater has been installed properly.Plumbing Permit Application
