Homeowner called us out due to a gas smell coming coming from the water heater in the garage. After further inspection, I found that the water heater vent hood was completely disconnected from the flue. I also found that there was a small gas from a connection on the heater. I replaced and adhered the vent hood along with new b vent connections to be heater, and I also replaced the sediment trap connecting to the water heater. Further work for the heater were recommended. Tested and check for leaks.
