Hi, I wish to replace my shower head only. It is a fixed head so just want to unscrew the old head (not the arm) and replace. Ordered a new one which was slightly different and it is too big to screw on. I contacted the supplier and they said I do not have a BS pipe. Mine is a tiny bit smaller. Is there anyway I can connect a fitting to make it BS at all or should I just send it back.?
