Turn off electric and gas, let heater cool, and remove the drain plug. You need to create an air pocket at the top of the water heater. That will stop the drip from the PRV. We only run on both when we know we will need more hot water in a short time. It is perfectly normal for the dripping, doesn't really hurt anything. We are fulltime, so shutting down the water heater for a little drip is a waste of time, so it drips sometimes.
