I am remodeling a shower and will be installing a Kohler k-303 Three valve shower valve (Hot, Cold & diverter).
For some reason the instructions say that I cannot use this valve with ceiling supplies.
I could certainly re-route the copper and bring the supplies in from below, but, for the life of me I can't figure out why they say not to use the three valve yoke with ceiling supplies.
(The also make a two valve yoke {without the diverter} and there is no such warning for this one).
Any ideas?
