I soldered a pipe on the downstream side of a ½ in ball valve and found a pinhole leak after turning on the valve. I drained the line and let the pipe dry, then heated the connection and removed the pipe from the valve body. How clean does the inside of the connection on the valve need to be before it can be re-soldered? If enough solder is removed to allow the pipe to fit, will that be good enough assuming I then sand and flux the connection? Or does the solder have to be removed to the bare brass?
