Hey guys I have an old delta faucet from 88 that just messed the bed. The diverter gave out and well...This is not a diverter that can be just changed out. It's a whole spout replacement deal. Here's the issue my spout is a 3/4 inch spout and all I can find are 1/2 inch replacements. I tried getting a delta faucet (universal) replacement with no luck either. It had all the fittings but...Here's the kicker...The fitting thats on the pipe looks or feels like it may have been soldered on. There is not a set screw so I'm not sure how to remove this. I tried applying heat from a torch and it didn't budge. I have a pic below of the setup. Any ideas or any way to point me in the right direction of just leaving the fitting on there and replacing the spout?
