Replacing older Moen tub faucet
First, let me say I'm plumbing challenged, so I hope I can explain this correctly. The Moen tub faucet with diverter that was installed new in my new house 7 years ago has broken. I went to the store to buy a new one but can't find a similar one anymore. The broken one has a 3/4" attachment (according to the Lowe's guy) and the newer ones are all 1/2" attachments. The end of the pipe that comes out of the wall where I will attach the faucet has a round 3/4" threaded metal piece on it that I can't undo. I think there is plumbers putty on it and I don't know how to get it off. Just past the metal piece there is a PVC nut that appears to be glued on.
My questions: Is there anywhere to get a Moen faucet just like I have? Failing that, how do I remove metal attachment that has the plumbers putty on it and will that then work with new faucet.
I would appreciate any help. Again, sorry if this isn't very clear!
