I will try to explain this as best I can so hopefully it will make sense. Kitchen sink, right side, copper pipe goes down to plastic goose neck, about the middle of the copper pipe was a welded/solder connection of a 1/2" copper line coming from the dishwasher, part of the run from the dishwasher is copper not the entire thing. I was changing the faucet last night and I hit that 1/2" pipe near the connection and it busted loose. So now I can't use that drain because water would come out.

My question: I wont solder it back myself so I am considering just calling a plumber and have them do it. I considered cutting the copper pipe above and below the old connection and inserting a plastic/rubber Y of some sort. I didn't know if they even make a Y with a large main diameter for the drain that would have a 1/2" dia stem on it for he dishwasher connection

I haven't messed with plumbing much so I know very little about the subject.
