Hey guys! I'm new to the forum and hate asking for help right off the bat BUT I'm currently stone walled. I am remodeling a master bathroom and I installed a Kolher Master Shower 3 way diverter to control a shower head, rainfall head in the ceiling, or both at the same time. I plan on running the lines to the fixtures with pex by installing a shark bite fitting at the copper tubes coming out of the diverter. I'm not sure how to run the lines to make the shower head and rainfall work at the same time. I have 3 outlets coming out of the diverter. One for the Rainhead, one for the shower head, and I don't know what I need to do with the third one. Are there any diagrams out there so show me what I need to do? See picture
