Review on Kohler 1014049 KOHLER K 1014049 Adapter by Brian Shakey

This is a stem driver. The part that comes out of the wall at the valve is connected to the handle. The shower valve handle has a plastic part that looks like a socket wrench. The stem driver broke, and after months of trying to locate the part, I called Kohler and emailed them a photo of the broken part. I was told right away that this is a STEM DRIVER. They sent me for free but I ordered one here as it was the holidays. The spare part is much heavier. So here's the deal. If you turn the knob on your Kohler shower and it doesn't work, this might be the little detail you need. STATE DRIVER.
