Upon entry into the home, customer brought me into the master bedroom bathroom. Customer informed me that the existing showerhead continuously leaks. This is a warranty job and I changed out the existing Kohler shower cartridge with a new Kohler shower cartridge and tested the system. As per video taken, I explained to customer that a majority of this water is trapped inside the flexible showerhead.. I proceeded to unscrew the showerhead to show him that no water was coming out of the shower arm, so the dripping is from the flexible shower line connected to the handheld shower head.
