I wonder if someone could advise me. I am replacing old Groche shower handle wall integrated bracket. The pipe was secured somehow but came loose behid the tiled wall (see photo). The connector has to be pushed back and stay in for the bracket to be nice and flush (see photo) but the pipe pushes it out so strongly that it's hard to hold it in place by hand. Is the a way to secure it somehow? I did try to wedge something and glue it perhaps but everything I tried just slides out. I want to avoid drilling as they are extremely hard porcelain tiles ( wasted 4 diamond drill bits to secure a radiator!) Any ideas? TIA
