Q."I have a diverter tub spout and whenever I fill my tub with water from the tub spout only, I also get some dripping out of my shower head. What can I do to stop that?" A. There could be many reasons why this is happening. One possible solution is to install a twin ell which is designed to help prevent the showerhead from dripping while the tub spout (diverter style) is filling the tub.
