Turn off the water to the house then open the valve then turn on a cold water faucet somewhere lower to get the water out of the line. If this is not possible keep the valve open and be prepared for the water in the copper line to have to boil off partially before the solder will melt. MAP gas helps as well since it burns hotter in the “water in the line” scenario
