Gas Water Heater Valve Replacement

The pressure-relief valve on my gas water heater drips constantly from the side port, so I need the valve removed and a new, properly rated one installed. Please bring the replacement T&P valve, fit it without damaging the tank threads, restore the water line, and fire the heater back up to confirm that there is no seepage under normal operating pressure. A simple photo set of the completed work and a short confirmation that the leak has stopped will close the job.
