Faulty diverter
As described by in a previous review, the inline diverter does not completely shut off the water from the rain head when diverted to the hand shower attachment. There is constant dripping on your head while your using the hand shower. The rail was installed in 2017 when we had a professional remodel done. The dripping started about 6 months ago. The valve was replaced and the dripping continues. I guess it is a flaw in design and we’re stuck with a drippy rainhead.
