I bought this unit for a Roman tub set up. After installation the plumber and I realized the handles (valves) turn a half turn rather than a quarter, as specified. So now my handles interfere with each other. Plus, the diverter will not allow the hand held shower to come on unless there is a lot of water pressure and the hand held shower will not cut off unless the water is turned off. It cannot be operated with the plunger behind the spout.
