Empty the grey into the black
Just wondering if anyone knows if both the black and the grey are mounted at the same height. We rarely use the black so it stays empty or close to (night time emergencies are the exception). My grey is full and I was thinking of keeping the cap on and opening both valves. I would just hate the little bit of black to overfill the grey into the shower. Thanks!!
