[468] First Gen Kohler Derry Urinals at UMA Engineering Lab

I was always wondering if Kohler had an older generation of the Derry urinal. I always knew Standard had the Expello, Crane had the Expedio, and Eljer had the Terminal. All of which went back into the 30s and 40s. Here's Kohler's answer to those. The first generation of the Derry. The right one has a lot more pressure than the left one here. Unfortunately stuck with a Placidus and an Afwall with hopeless flushometers.
