Small pipe attached to shower head broke off
We were changing the shower head and the 3-4 inch pipe attached to the shower head broke off and parts of it corroded into the 3 -4 inch pipe in the wall that . I don't want to damage the threads to get the very thin lining of the other pipe in so we can screw a new shower head in. It had not been changed in 15 years and I guess the water corroded the pipe, so that the copper pipe that is in the wall has a little bit of the shower head pipe in it? Is there an easier way to get the metal out so we don't have to cut off the top of the pipe in the wall and sodder it? Thank you for any help !:) Marjorie
