Hi, we need to replace our shower arm because the old one was leaking. After taking off the shower arm there is a pipe protruding from the wall that doesn't allow us to screw a new one in. Can someone help diagnose what this is and what we need to do. I bought a screw fit one from Amazon but can't screw it into the wall, and have just bought this push fit one (link below) but having just received it the parts which I thought would go on over the pipe don't fit so I'm back to square one.
