Upon inspection, the gas valve was identified as the source of a leak at the orifice. I carefully disassembled the valve to access the internal components. After identifying the faulty orifice, I replaced it with a new one, ensuring a precise fit. I then reassembled the valve and conducted a thorough test to confirm the leak was resolved. The system was checked for proper operation, and all safety protocols were followed to ensure the job was completed efficiently and safely.
