I recently installed a new Shower head, Diverter, and tub spout w/ diverter. When filling the tub shower head also sprays water. I removed the tub spout and turn the water on and the problem went away. I figured something was wrong with the tub spout, so I tried a different one and still had the same problem. It seems like the tub spout is adding the backpressure needed to make this happen. Is there a solution to this?
