Greeting's, I have a Kohler 11748 bath/shower valve which with built in diverter. I was planing to install it with the tub port to the shower and shower port to the tub. This was to make the water go to the shower without pressing the diverter. However shower port hole is smaller than the tub port hole. I'd like to know if I increase the smaller port hole size will I get more water out of it?
