Found the two handle moen shower valve has a diverter stem that distributes water from the shower head and sprayer arm Customer education on the valve stem and a little on the operation of the valve and diverter, Customer was unaware the diverter valve could pull out or close shut, fairly the main assumption was the left to right turning to displace water from sprayer to shower head Customer had questions abojt the installation of a raul shower head The existing shower head has a female threaded adt in the wall and the new shower head is a female thread Cutting open the drywall in the opposite wall to remove the existing shower arm 90 and install a male shower arm 90 to further install the Raul rain shower head
