I am attempting to remove an old Standadyne spout. This spout is hollow through the majority of its length and appears to be connected at the end. I cannot see or feel a set screw so I assumed it is a screw on spout. I was able to break the spout loose, but it does not screw off after many rotations. In fact, as it turns it vibrates as if there is a set screw.
Spout was very cheap. The plastic shell had broken away from the copper screw on coupler, so the shell was just turning in my hands. I ended up cutting the plastic off to expose the coupler. From there, I could loosen the coupler with help of liquid wrench. Not very elegant, but the job is done. Now to replace it with a better spout.
