I have read multiple articles across the web regarding changing the spout on a tub. They all claim this is a straightforward, relatively easy process. However, that hasn't been the case with me.
I'll refer to this web site, since yet has photos included: How to Replace a Bathtub Spout | The Family Handyman
This web site claims there are two types of spouts: spouts with a setscrew and slip onto the pipe, and spouts that have a threaded base that screw on to the pipe. My current spout is a screw on.
The site claims if you have a screw-on spout that you simply unscrew the old spout, and screw on the new spout. However, I have purchased two spouts that don't work. My current spout (pictured below) has a threaded base that goes all the way from the rear of the spout to the front of the spout. The only spouts I can find in a store have one single threaded base at the rear of the spout.
The problem with these types of spouts on my tub is that the pipe coming from the wall has some type of large apparatus attached to it. Thusly, the new spouts are too small to fit around this apparatus and screw on at the rear of the pipe.
I'm not sure if I'm supposed to detach this apparatus before attaching the new spout or what? I've included pictures below. Any help would be very, very much appreciated!
Photo 1: The old spout. Notice how the threaded base goes all the way from the rear of the spout to the front of the spout. This threaded base narrows as it moves towards the front of the spout. I assume this is to fit a variety of pipe sizes.
Photo 2: The pipe. Notice the large, bulky attachment. This is preventing any new spout from fitting.
Photo 3: New spout. Notice the difference in the threaded base compare to the old spout. The threaded base on this spout does not fit over the apparatus on the pipe coming from the wall.
