The diverter in my bathtub spout has stopped working, and I want to replace the spout. When I removed it, I found this adapter, which appears to be soldered to the copper pipe (or at least I was unable to remove it, and I don’t see any threads behind it).

Can anyone identify what type of adapter this is, or help me find a spout that might fit? Otherwise, I’m afraid I’ll need to bring in a plumber to give me a more standard setup with a 1/2” nipple coming out from the wall. Really hoping I can avoid that expense.

Bath tub spout adapter

The outer diameter of the threaded part at the back is about 1-1/4”. I’ve been unable to find any spouts that fit that. All the ones I’ve found fit only 1/2” or 3/4” pipe.

There are no marking on the adapter or the old spout, so I’m not sure what brand they are.

    Looks like solder at the front of it, too. Weird one. I'd guess the o-ring was removed and this was soldered over the pipe stub sticking out of the wall, o-ring replaced, spout slipped over and screwed on.

I don’t know the brand but a plumber is not needed you could do it with a 45$ torch if you don’t have one.

I would pull the o ring and heat the end with a torch using players to hold the outer brass (yellow metal), make Sure to put some wet towels down as you slip the fitting off you don’t want the hot solder to damage the tub. I like mapp Gas torches over propane they get hotter and make removal of sweated parts easier. Mapp has is the yellow bottle, my torch can use both types some built for propane can’t handle the higher heat of mapp gas. Then a new spigot for copper pipe could be installed.

  • I don’t have a torch, but could a heat gun do it?

  • No , that’s why I mentioned the type of torch that would be best in my opinion , much cheaper than a plumber and now you would have a tool that can be used for more than this one job at less than the cost of a plumber. A hair dryer or even a heat gun is not close to the 700 or so degrees Fahrenheit needed to melt solder.

  • Well, I had a plumber come out this morning, and they did... exactly this. (And yes, buying a torch would’ve been much cheaper. I basically called the plumber because I didn’t quite trust myself with a torch.)

  • Understandable but I hoped you could watch and possibly next time you can give it a try.
