Is there a way to bypass a shower pipe, i.e. convert a tub/shower diverter spout to a plain tub spout, such that the water will not go up the pipes in the wall to the shower head? It seems the shower pipe is leaking; no drips below when the diverter is set to tub, and drips when set to shower. I'd rather not have to get a plumber to open the wall to replace the shower pipe. I tried connecting a handheld shower hose to the existing spout, and attaching a ball valve before the shower head; the drip slows down but there is still water going up the shower pipe in the wall (when I turn the ball valve open, water comes out of both the shower head and tub). I was hoping that gravity would cause water to stay down out of the shower pipe and to go only into the handheld shower head. Apparently the resistance provided by the handheld shower head is enough to force the water up the shower pipe in the wall. (BTW, appearance is not a big concern, so any solution that would stop the drip would be appreciated.)
