Struggling with stuck brass extension piece and white thing on tub plate – any DIY tips for upgrading without hiring a plumber?

Hey there! I’m currently trying to replace the tub faucet, but I’m having some trouble with this big brass extension piece that seems to be stuck on the pipe. I’m not sure how to remove it.
I also noticed another white thing when working on the tub plate, but I got a bit stuck and ended up putting everything back together. I’m hoping to upgrade without having to call in a plumber, so any help or suggestions would be greatly appreciated!
I’ve attached photos for reference – the first one shows where I’m having trouble, the second one is the new hardware, and the last one is the trim/knob plate.
You can use a torch and pliers to heat up the adapter and remove it.
It’s definitely soldered on, and that replacement spout is no good. I’ve been a Trade Master Plumber for 42 years
I agree with .
Moen has trim kits available that will work with the soldered adapter. I suggest returning your current purchase and finding a replacement that fits the existing setup.
If you can’t find a set screw for an Allen key, it’s probably soldered on. Heat up the yellow (brass) adapter with a torch, then pull it off with pliers. Sand down the copper stub and debur the pipe. Upgrade to a higher quality spout, like a matte black “split spout”. And don’t forget to use a delta trim for the finishing touch
Save yourself the trouble of making a huge mess with a torch and call a professional to do the job right
I’m pretty sure these are all soldered onto the pipe
Instead of trying to salvage it, cut off the old piece and swap out the entire faucet with a new fitting
That’s a delta adapter. Keep it and just purchase another delta or reach out to them and they might send you a replacement for free
Check out Amazon or a supply house for a tub filler from Happy Time Panda Company, recommended by . 🤷♀️
What are you talking about, ?
Before you resort to cutting, check if there’s a set screw on the brass piece. If you do cut it, you’ll need to solder on a new piece that may not fit over the coupling
Simply return the new tub spout and exchange it for a Delta in the finish of your choice
You’ll need a pipe wrench to detach the outer pipe, or two if you want to play it safe (one on each pipe, turning in opposite directions), as well as a cartridge puller to take out the white piece (the cartridge). Remember to turn off the water first because that white piece is holding back a ton of water.
