Example Input: I have had this installed in my wall with a square rainfall shower head for only three months (almost to the day). This morning the pipe broke inside the wall where it screws into the brass plumbing. It rusted the threads and sheared of upon attempting to unscrew the pipe. Additionally the pipe shows rust damage all over. Due to the terrible quality of material I now have thousands of dollars worth of damage to my house to to this pipe breaking and leaking behind my wall, flooding the ceiling below as well as the wall.
