Is a drain pan required for the replacement of existing water heaters?
RP2801.5 Required pan. Where water heaters or hot water storage tanks are installed in locations where leakage of the tanks or connections will cause damage, the tank or water heater shall be installed in a galvanized steel pan having a minimum thickness of 24 gage (0.016 inch) (0.4 mm) or other pans listed for such use. All new water heater installations require a drain pan and drain. Existing water heater installation that was approved under a previous code and does not have an existing drain pan and drain, which is installed in a location where leakage from the water heater will not cause structural damage, will not be required to have a drain pan and drain installed when replaced.
