Hi everyone! I am at the point where I will be installing my travertine coping. I have a question regarding the capped pipe(aerators) that I have currently that’s pointing strait up. The shotcrete guys etched a space for it and my plumber said that I need to set it prior to putting the coping down. Question is do I use the current piping there and cut it add a 90 degree elbow? If so how much does the threaded piece need to stick out past the shotcrete? I can post pictures tomorrow if my description isn’t making sense... Thank you in advance!
