A tub filler spout with a diverter is installed in my spa tub. It doesn't have a shower. I want to add a hand-held shower, but the diverter prevents me from doing this (it is one of those pull-down from the spout types). How do I remove the spout, twist or pull? I have gently tried both, but it is very sluggish. I don't want to damage the pipe connection.
