Did you actually pull the cartridge out and look on the bottom for the small steel tab? I know that I initially tried just turning the cartridge and it didn't help. I had to actually take the metal tab off of the bottom of the cartridge and turn it 90 degrees and then the handle rotated the correct way. Well, the handle would rotate the right way *and* the water would come on/off appropriately.
Yeah, take a picture with the handles off and also a picture of the cartridge.
