Hi there - thank you in advance ~
Should be a fairly easy question - I am installing a new tub spout in a remodeled bath. I had a plumber install a new shower valve - for the tub spout rough in, he just left copper pipe protruding from the wall with no threaded pipe to screw the spout into.

What do I need to do to get the threaded piece on the copper in order to be able to thread the tub spout on?

Thanks again!
